Transcription

Front

What is transcription?

Back

Transcription is the process by which the genetic code of DNA is copied into a strand of RNA.

Front

Where does transcription occur in a cell?

Back

Transcription takes place in the nucleus of the cell.

Front

How is the DNA sequence GCTATA transcribed to mRNA?

Back

The DNA sequence GCTATA is transcribed to mRNA as CGAUAU.

Front

What part of a nucleotide accounts for genetic variation?

Back

The nitrogenous base of a nucleotide accounts for genetic variation between individuals.

Front

What base does RNA have instead of thymine?

Back

RNA has uracil instead of thymine.

Front

What are the three main types of RNA?

Back

The three main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Front

What is the role of mRNA in transcription?

Back

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

Front

What is the function of RNA polymerase?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.
