Which does not occur during translation? tRNA pairs with complementary mRNA. A peptide bond is created between amino acids. DNA is transcribed into a complementary strand of mRNA. A chain of amino acids, linked by peptide bonds, is formed..

Sagot :

The transcription of DNA into a complementary strand of mRNA does not take place in translation.  

In genetics and molecular biology, translation refers to the procedure in which ribosomes in the Endoplasmic reticulum or cytoplasm produce proteins after the procedure of transcription of DNA to RNA takes place in the nucleus of the cell.  

In translation, the mRNA is deciphered in a ribosome to generate a particular chain of amino acid or polypeptide.  

DNA transcription into a complementary strand of mRNA does not occur during translation process.

Further Explanation

Translation  

  • Translation refers to the process by which proteins are synthesized in the cell. The process takes place in organelles known as ribosomes found either freely suspended in the cytoplasm or attached to the surface of the rough endoplasmic reticulum.
  • During the process of translate the genetic code carried by the messenger RNA is decoded by the help of a transfer RNA and is used to make sequence of amino acids and then proteins.
  • mRNA contains codons such that each codon codes for a specific amino acids.
  • Each codon is decoded to form an amino acid that is attached to another and so forth forming a polypeptide and consequently a protein.
  • Codon in this case refers to a three nucleotide bases that are read together during translation and codes for a particular amino acid.
  • tRNA is responsible for bringing amino acids to the ribosomes since it contains the anticodons that are complementary to the codons on the mRNA

Transcription

  • This is the process that occurs before translation in the nucleus of a cell. Information carried by the DNA is copied to a complementary messenger RNA.
  • The process of transcription is catalyzed by enzyme RNA polymerase which acts on DNA to produce a molecule of mRNA.
