how are RER is involved in peptide Bond formation ?
Answers
Answer:
The ribosomes peptidyl transfersof growing polypeptide chain from the p site tRNA to the amino group of the a site amino acid this creates a peptide bond between the c terminus of growing polypeptide chain and the A site amino acid
Answer:
So far, we've had a lot of practice with the process of translation. It's the second step in the central dogma, which involves converting the genetic code in mRNA into a chain of amino acids. During translation, tRNA molecules first match up with the amino acids that fit their attachment sites. Then, they attach to the mRNA strand by matching their anticodons to the mRNA codons. We know that amino acids are assembled in the correct order because of good codon recognition. But, how do we begin polypeptide assembly? Do the amino acids just magically bond together? How do we make sure we get the tRNA, the mRNA, and the amino acids all in the same place at the same time?
You may recall a tiny structure in the cell called a ribosome. Ribosomes are the little 'dots' that live on the rough endoplasmic reticulum surrounding the nucleus of a cell. They are very important organelles that make polypeptide assembly possible. In this lesson, we're going to focus on the ribosome and the role it plays in helping to begin genetic translation.
