Question

In order to produce many copies of a protein fast, the cell uses ______.

Options

• DNA replication.

• single-unit ribosomes for high-speed translation.

• codon-anticodon reciprocal duplication.

• many RNA polymerase molecules to produce mRNA transcripts at the same time.

Answer 1

In order to produce many copies of a protein fast, the cell uses many RNA polymerase molecules to produce mRNA transcripts at the same time.

Explanation:

To produce a large quantity of protein quickly, a cell maximises efficiency at two main stages. First, many RNA polymerase molecules can simultaneously transcribe the same gene, creating a high volume of mRNA transcripts. Second, once these transcripts reach the cytoplasm, multiple ribosomes, often referred to as a polysome or polyribosome, can attach to a single mRNA molecule to translate it into proteins at the same time. This parallel processing ensures that the cell can respond rapidly to environmental changes or growth needs without waiting for one protein molecule to be finished before starting the next.
