Question

5) Which of these explanations best describes how a gene is expressed to make a protein?

A) The instructions in DNA are used to produce an RNA molecule that is used to build a protein at the ribosome.
B) The DNA copies its entire genome into RNA, which is then broken into gene components that are translated at the ribosome.
The specific gene that codes for a protein leaves the nucleus of a cell and travels through the cytoplasm to the ribosome.
D) A specific gene is removed so that it can be copied and then transcribed into RNA, which is used to build the protein in the nucleus.

Answer 1

The best explanation for how a gene is expressed to make a protein is option A) The instructions in DNA are used to produce an RNA molecule that is used to build a protein at the ribosome.

How a gene is expressed to make a protein?

Translation and transcription are the two main processes. Gene expression is the combined term for transcription and translation. The information contained in a gene's DNA is transferred to a molecule called RNA (ribonucleic acid) in the cell nucleus during the transcription process.

The process of creating an RNA copy of a gene's DNA sequence is known as transcription in the context of genomics. The messenger RNA (mRNA) copy carries the DNA-encoded protein information of the gene.
