During the first step of gene expression, an RNA copy of a gene is made. Which of the following represents the correct sequence produced from a gene segment with the following sequence: GAACTAAGC?

Question

Quizplus · Accepted Answer

The first step of gene expression involves transcription, where an RNA copy of a DNA sequence is made. In RNA, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G). Therefore, the DNA sequence GAACTAAGC would be transcribed to the RNA sequence CUUGAUUCG, matching option A.
