Question

I just need these three questions checked please. I answered them, but the wording of the answers are a bit tricky. I just want to make sure I wasn't tricked. My answers are in bold. Thank you to whoever can check my answers.

1) Human genes have di-nucleotide sequences at the 5’ and 3’ ends of the intron as 5’gt…ag3’. Which of the following most accurately describes the outcome if a mutation occurs at the 5’ splicing site (gt) of a human gene?

A. The mRNA will be longer

B. The mRNA will be shorter

C. The polypeptide will be longer

D. The polypeptide will be shorter

2) If the initiation codon is mutated in a gene (nonsense mutation), what will happen to the mRNA of this gene?

Nothing

The mRNA will be longer

The mRNA will be shorter

There will be more mRNA

There will be less mRNA

3) Individual genomes vary from each other including Indels, SNPs, Copy number variants, etc. Some of these variations do not affect gene function. Which of the following gene region will most likely carry these differences?

Promoter

Initiation codon

Termination codon

Intron

Splicing signals

Nothing

The mRNA will be longer

The mRNA will be shorter

There will be more mRNA

There will be less mRNA
