Question 1

During which stage of the cell cycle are gene mutations most likely to happen?

Answer 1

Interphase

Question 2

Why are gene mutations most likely to occur during Interphase?

Answer 2

Gene replication and it is the longest stage

Question 3

2 differences between the structure of mRNA and tRNA

Answer 3

1. mRNA has no binding sites for amino acids whereas the clover leaf shape of tRNA has binding sites
2. mRNA has no hydrogen bonds whereas tRNA does have hydrogen bonds

Question 4

What is the proteome of a cell

Answer 4

The DIFFERENT number of proteins a cell can produce

Question 5

Why are hydrogen bonds important in cellulose molecules?

Answer 5

Many weak hydrogen bonds layered to make chains of microvilli, increasing the stability and strength of the cellulose molecule
