Unit 1 - Genes and Proteins in Health and Disease Flashcards
1
Q
What is a mutation?
A
2
Q
Explain Nonsense (In Biology terms)…
A
When a mutation occurs and a stop codon is coded prematurely, rendering the protein produced useless.
3
Q
What does Missense mean?
A
When a mutation occurs and changes the amino acids that are coded, thus producing a protein which doesn’t do the right job.
4
Q
Explain what Frameshift is…
A
When a nucleotide has been added or deleted, it effects all the sequences after it and thus all the amino acids coded for after the mutation are different. This is called frameshift.
