What is meant by the term "transcription"?

Short Answer

Expert verified

The transfer of genetic information from DNA by the formation of mRNA is called transcription.

Step by step solution

01

Introduction

The process of converting genetic information from DNA to mRNA is known as transcription.

DNA鈫�transcriptionmRNA

Transcription begins when the section of DNA containing the gene to be reproduced slides away. A polymerase enzyme inside of this unwinding DNA recognises the signal to start mRNA production. DNA nucleotides link to ribonucleotides in the following order:

G鈫�C,C鈫�G,T鈫�A,A鈫�U

02

Explanation

The polymerase enzyme forms bonds among nucleotides as it proceeds along undamaged DNA. The RNA polymerase reaches the termination site, signalling the conclusion of transcription. As a result, mRNA produces comparable nucleotides, thus DNA's double helix shape is restored.
