Question

Which of the following is primarily responsible for the coding of the amino acids used in the synthesis of cellular proteins?

A.
Golgi apparatus
B.
transfer RNA
C.
ribosomes
D.
DNA

Answer 1

The right answer to this question is option D. Dna.

Step-by-step explanation:

The synthesis of cellular proteins is based on two main things, transcription and translation. The transcription is when the polymerase RNA reads a ribbon os DNA, changing the nucleotides. The nucleotide that is changed is only one in the new ribbon, DNA holds thymine, and this is changed to uracil, this ribbon is called mRNA. After that, this ribbon goes outside of the cell and the process continues with the tRNA and the ribosomes.

Answer 2

The DNA hold the code for the synthesis of the various cellular proteins. An mRNA molecule is first synthesised from the DNA. This mRNA holds the code for every amino acid present in the protein molecule in the form of a 3-base codon. When the mRNA is being read by the ribosome during the process of translation, these codons help the ribosome to correctly pick the amino acid in a defined sequential manner.
