Respuesta :

Iqta

Answer:

30.

  1. B. nitrogen bases
  2. B. It translates genetic information in mRNA

31.

  1. C. On a ribosome

Explanation:

Translation:

  • Translation is the final step in the central dogma of molecular biology that involves the decoding and translation of the codons on mRNA to amino acid sequence.
  • The genetic code is a scheme of 64 triplet nitrogeneous base codons that code for 20 amino acids.
  • A tRNA molecule reads this codon sequence with the help of complementary anticodons and helps transport an amino acid to the ribosome for addition to the growing polypeptide chain.
  • Protein synthesis occurs in the rough endoplasmic reticulum (RER) in the cytoplasm.
