TranslationMultiple Choiceinvolves formation of peptide bonds between adjacent amino acids.requires three types of DNA.requires the pairing of codons on tRNA with anticodons on mRNA.involves copying RNA from DNA molecules.All of the choices are correct.
Solution
The correct answer is "involves formation of peptide bonds between adjacent amino acids."
Here's the step by step explanation:
-
Translation is the process in protein synthesis where the information from a mRNA (messenger RNA) is used to create a polypeptide chain (protein).
-
This process begins when the mRNA leaves the nucleus and goes to the ribosome, the site of protein synthesis.
-
The mRNA carries the genetic information in the form of codons, which are groups of three nucleotides.
-
Each codon corresponds to a specific amino acid.
-
tRNA (transfer RNA) molecules carry the appropriate amino acids to the ribosome. Each tRNA has an anticodon that matches the codon on the mRNA.
-
The ribosome facilitates the pairing of the tRNA anticodon with the mRNA codon.
-
Once the tRNA is bound to the mRNA, the amino acid it carries is added to the growing polypeptide chain. This is done through
