Question

Where does the protien-building begin? A. enzyme B. cytoskeleton C. DNA D. cell membrane

Answer 1

Answer: Option C

Explanation:

Protein building begins on the DNA strand. Usually, the DNA contains genetic information which flows from nucleic acids to proteins in a series of steps:

1) Replication: this is the first step. It involves the copying of parental DNA into daughter copies.

2) Transcription: this is the second step. Here, parts of the coded genetic message in DNA are copied precisely in the form of RNA - in the form of messenger RNA (mRNA).

3) Translation: this is the third step. Here, genetic message coded in mRNA is translated, on the ribosomes, into a protein with a specific sequence of amino acids.

Simply put, DNA makes RNA, and RNA makes protein.
