Protein synthesis requires the use of mRNA, which Protein synthesis requires the use of mRNA, which carries the message to the nucleus to synthesize new DNA during cell division. is translated by the ribosomes into the amino acid sequences of proteins. is made in the nucleolus. must be made by the ribosomes.

is translated by the ribosomes into the amino acid sequences of proteins.

Explanation:

Protein synthesis is also called gene expression and it involves how the information in a DNA molecule to used to synthesize useful gene products called proteins. The process of synthesizing proteins in living cells occurs in two major stages namely: transcription and translation.

Transcription generally involves the synthesis of a mRNA molecule using a DNA template. The mRNA transcript is then used to direct the synthesis of Protein in the next stage (translation). Translation, which occurs in the ribosome, involves the use of the mRNA nucleotide sequence to produce an amino acid sequence, which will eventually become a protein.

Protein synthesis requires the use of mRNA, which is translated by the ribosomes into the amino sequences of proteins.
