mutations

Question 1

what is a change to a base called

Answer 1

a mutation

Question 2

if a single base has changed what happens to the shape of a protein

Answer 2

a single base has changed this doesn’t change the amino acid sequence as different base triplets can code for the same amino acid

Question 3

if the protein has a different amino acid what happens to it’s shape

Answer 3

if the protein has a different amino acid its shape will change. This can change the function of a protein as the active site of an enzyme may change shape so it no longer fits its substrate

Question 4

what happens if the chromosomes also contain non coding parts of DNA

Answer 4

THESE REGIONS SWITCH GENES ON/OFF
AND TELL GENES WHEN TO PRODUCE PROTEINS

If mutated these non coding sections can affect how genes are turned on/off this means the cell could produce a protein that it’s not meant to at that time
