Transcription

Question 1

What is gene expression and what is it split into?

Answer 1

The way DNA controls characteristics is through protein synthesis.
Which is also called gene expression.
Transcription and translation and it involves RNA

Question 2

What is the purpose of transcription and translation?

Answer 2

These processes work together to create a polypeptide which folds to make a functional protein. Proteins carry many essential functions in cells

Question 3

What is transcription?

Answer 3

the process by which an RNA sequence is produced from a DNA template

Question 4

What is messenger rna?

Answer 4

A transcript copy of a gene used to encode a polypeptide

Question 5

What is transfer rna?

Answer 5

A clover leaf shaped sequence that carries an amino acid

Question 6

What is ribosomal rna?

Answer 6

A primary component of ribosomes

Question 7

Transcription model answer

Answer 7

a. DNA strands are separated by breaking hydrogen bonds
b. Transcription is the synthesis of an mRNA copy of a gene;
c. The copy is complementary to the DNA template/antisense strand;
d. RNA polymerase attaches to DNA
e. RNA nucleotides matched to exposed complementary bases;
f. Adjacent nucleotides are joined by a phosphodiester bond together to make a strand of mRNA;
g. mRNA molecule separates from DNA
h. Pre-mRNA is spliced to remove introns
i. Mature mRNA leaves the nucleus through nuclear pores
