Transcription

Front

What is transcription?

Back

Transcription is the process by which the genetic information in DNA is copied into messenger RNA (mRNA).

Front

What are the base pairing rules in RNA transcription?

Back

In RNA transcription, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).

Front

What is the role of mRNA?

Back

mRNA serves as a template for protein synthesis, carrying the genetic code from DNA to the ribosome.

Front

How many nucleotides make up a codon?

Back

A codon is made up of three nucleotides.

Front

What is the significance of the start codon?

Back

The start codon (AUG) signals the beginning of protein synthesis and codes for the amino acid methionine.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of copying DNA into RNA, while translation is the process of synthesizing proteins from mRNA.

Front

What enzyme is responsible for transcription?

Back

RNA polymerase is the enzyme that synthesizes RNA from a DNA template during transcription.

Front

What is a DNA template strand?

Back

The DNA template strand is the strand of DNA that is used as a guide for synthesizing RNA during transcription.

Front

What is the function of RNA polymerase?

Back

RNA polymerase unwinds the DNA and synthesizes a complementary RNA strand during transcription.

Front

What is the role of introns and exons in mRNA?

Back

Introns are non-coding regions that are removed from mRNA, while exons are coding regions that are expressed in the final mRNA.
