A transfer RNA (abbreviated tRNA and archaically referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length, that serves as the physical link between the mRNA and the amino acid sequence of proteins. It does this by carrying an amino acid to the protein synthetic machinery of a cell (ribosome) as directed by a three-nucleotide sequence (codon) in a messenger RNA (mRNA). As such, tRNAs are a necessary component of translation, the biological synthesis of new proteins according to the genetic code.
The specific nucleotide sequence of an mRNA specifies which amino acids are incorporated into the protein product of the gene from which the mRNA is transcribed, and the role of tRNA is to specify which sequence from the genetic code corresponds to which amino acid. One end of the tRNA matches the genetic code in a three-nucleotide sequence called the anticodon. The anticodon forms three base pairs with a codon in mRNA during protein biosynthesis. The mRNA encodes a protein as a series of contiguous codons, each of which is recognized by a particular tRNA. On the other end of the tRNA is a covalent attachment to the amino acid that corresponds to the anticodon sequence. Each type of tRNA molecule can be attached to only one type of amino acid, so each organism has many types of tRNA (in fact, because the genetic code contains multiple codons that specify the same amino acid, there are several tRNA molecules bearing different anticodons which also carry the same amino acid).

Structure of tRNA
The tRNA has a cloverleaf like structure. It is synthesized in the nucleus on a small part of DNA. In 1965, R.W. Holley suggested the cloverleaf model of tRNA. Though tRNA molecule consists of a single strand, it assumes clover leaf like structure through folding. There are three folds in the clover leaf tRNA. It has four arms namely anticodon arm, D arm, T C arm and aminoacid acceptor arm. The tRNA molecules are made up of 73 to 93 ribonucleotides. The acceptor arm carries an aminoacid. The anticodon arm has three anticodon nucleotides, which will join with the complementary codon in mRNA during protein synthesis i.e. three nucleotides in the tRNA pairs with three nucleotides of mRNA. In certain tRNAs in addition to these four arms an extra arm called variable arm. The aminoacid acceptor ...

Thanks for stopping by, this is 2 minute classroom and today we are talking about RNA, specifically mRNA, rRNA, and tRNA.
Let’s start with mRNA or messenger RNA, so named because it acts as the messenger between DNA and protein production. And if you want to know the differences between RNA and DNA, I have a great video for that linked here and in the description.
When you discuss RNA in school, you are usually learning about mRNA. During transcription, DNA is “transcribed” into mRNA. This mRNA is then translated into protein. It serves as the genetic template of a protein since the DNA can’t leave the nucleus.
Next, we have tRNA or transfer RNA. This is my personal favorite and honestly one of the most fascinating molecules in genetics. RNA is generally single-stranded, but tRNA actually folds back onto itself to form a distinct “t” like shape. Without going too deep, transfer RNA is responsible for bringing amino acids together during translation to form the growing peptide chain that will become a protein.
Last but not least is rRNA or Ribosomal RNA. This RNA is a main component of ribosomes, which I have discussed in a previous video. rRNA combines with special proteins to form ribosomes which then “read” mRNA to form proteins. There was a lot in that sentence, so feel free to jump back and listen again if you need to. But essentially, ribosomes contain rRNA and help build proteins.
To bring it all together, sections of DNA are transcribed into mRNA, which is brought from the nucleus to the ribosome (composed of rRNA and protein) the mRNA is then read by the ribosome, which brings the tRNA in with the appropriate amino acids to build whatever protein the mRNA is a template for. It gets much more complicated, but that is a video for another time.

Vocabulary in this video includes DNA, mRNA, rRNA, and tRNA. This video mentions that proteins can be made of 1 or more polypeptide chains and that proteins typically experience folding and other modifications (to be functional proteins.) Codons and the amino acids they code for are represented by standard charts that can be found in the public domain. While the rectangle chart is the common format, there may be other ways to represent the information. P.S. If learning about mutations, check out this cool codon chart that includes mutations(!!) in the public domain: https://commons.wikimedia.org/wiki/File:Notable_mutations.svg
Our videos are designed to introduce basic concepts and hopefully to inspire students to stay curious about the content. We simply cannot include all of the exceptions and minute details in a video under 10 minutes, and this is why we so frequently remind people of this in our videos. We want students to go beyond our videos to explore the depth of the material.
P.S. On our website, we emphasize that our videos contain science comics- not scientific illustrations. In real life, amoebas don't look like our characters. Our illustrated cell cartoons are definitely not to scale. Nitrogen and carbon don't tap dance. DNA is right-handed (but there are exceptions- worth a google) and doesn't have eyes...a face...or a top hat...

The tRNA has a cloverleaf like structure. It is synthesized in the nucleus on a small part of DNA. In 1965, R.W. Holley suggested the cloverleaf model of tRNA. Though tRNA molecule consists of a single strand, it assumes clover leaf like structure through folding. There are three folds in the clover leaf tRNA. It has four arms namely anticodon arm, D arm, T C arm and aminoacid acceptor arm. The tRNA molecules are made up of 73 to 93 ribonucleotides. The acceptor arm carries an aminoacid. The anticodon arm has three anticodon nucleotides, which will join with the complementary codon in mRNA during protein synthesis i.e. three nucleotides in the tRNA pairs with three nucleotides of mRNA.

Vocabulary in this video includes DNA, mRNA, rRNA, and tRNA. This video mentions that proteins can be made of 1 or more polypeptide chains and that proteins typically experience folding and other modifications (to be functional proteins.) Codons and the amino acids they code for are represented by standard charts that can be found in the public domain. While the rectangle chart is the common format, there may be other ways to represent the information. P.S. If learning about mutations, check out this cool codon chart that includes mutations(!!) in the public domain: https://commons.wikimedia.org/wiki/File:Notable_mutations.svg
Our videos are designed to introduce basic concepts and hopefully to inspire students to stay curious about the content. We simply cannot include all of the exceptions and minute details in a video under 10 minutes, and this is why we so frequently remind people of this in our videos. We want students to go beyond our videos to explore the depth of the material.
P.S. On our website, we emphasize that our videos contain science comics- not scientific illustrations. In real life, amoebas don't look like our characters. Our illustrated cell cartoons are definitely not to scale. Nitrogen and carbon don't tap dance. DNA is right-handed (but there are exceptions- worth a google) and doesn't have eyes...a face...or a top hat...

A transfer RNA (abbreviated tRNA and archaically referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length, that serves as the physical link between the mRNA and the amino acid sequence of proteins. It does this by carrying an amino acid to the protein synthetic machinery of a cell (ribosome) as directed by a three-nucleotide sequence (codon) in a messenger RNA (mRNA). As such, tRNAs are a necessary component of translation, the biological synthesis of new proteins according to the genetic code.
The specific nucleotide sequence of an mRNA specifies which amino acids are incorporated into the protein product of the gene from which the mRNA is transcribed, and the role of tRNA is to specify which sequence from the genetic code corresponds to which amino acid. One end of the tRNA matches the genetic code in a three-nucleotide sequence called the anticodon. The anticodon forms three base pairs with a codon in mRNA during protein biosynthesis. The mRNA encodes a protein as a series of contiguous codons, each of which is recognized by a particular tRNA. On the other end of the tRNA is a covalent attachment to the amino acid that corresponds to the anticodon sequence. Each type of tRNA molecule can be attached to only one type of amino acid, so each organism has many types of tRNA (in fact, because the genetic code contains multiple codons that specify the same amino acid, there are several tRNA molecules bearing different anticodons which also carry the same amino acid).

Briefly, to get nucleic acid (DNA or RNA) into a cell, you need to transfect the cell. It’s how the mRNA vaccines work, by transferring foreign genetic material (RNA or DNA) into the cell – a process that should not normally happen.
RNA, or ... ribosomal RNA (rRNA), which helps “read” the mRNA instructions; and transfer RNA (tRNA) which brings individual amino acids to the ribosomes and puts them together into functional proteins.
It is clear that TRIM25, as a so-called ubiquitin E3 ligase, triggers the immune system's response to viral RNA by transferring the molecule ubiquitin to the protein RIG-I, which then activates the immune defense.
