The Reflection on Transcription Process

What is the process of transcription and how does it affect the sequence of bases in RNA?

Options: DNA, RNA, Transcription

Answer:

Transcription is the process in which an RNA molecule is synthesized from a DNA template. During transcription, an enzyme called RNA polymerase reads the DNA sequence and synthesizes an RNA molecule that is complementary to one of the DNA strands.

Transcription is a crucial process in molecular biology that allows the genetic information stored in DNA to be transcribed into RNA. This process is necessary for the expression of genes and the production of proteins in living organisms.

After transcription, the sequence or order of bases in RNA is complementary to the sequence on the unused non-template DNA strand of the original DNA molecule. This complementary base pairing ensures that the RNA molecule carries the genetic information encoded in the DNA.

Specifically, in RNA, adenine (A) pairs with uracil (U) instead of thymine (T), guanine (G) pairs with cytosine (C), and cytosine (C) still pairs with guanine (G), just as in the non-template DNA strand. This complementary base pairing is essential for the accurate transfer of genetic information during protein synthesis.

The RNA molecule transcribed during the transcription process, often referred to as messenger RNA (mRNA), serves as a template for protein synthesis during translation. The order of bases in the RNA is crucial in determining the amino acid sequence of the protein that will be produced.
