Consider the following DNA sequence:
3' -- -- 5'
Its mRNA transcript will be:
5' -- -- 3'
The resulting polypeptide will be:
(START) THR-GLY-ASN-VAL-CYS-TYR-ARG-GLN-VAL -MET-VAL (STOP)
POINT MUTATIONS are errors in DNA replication in which only on nucleotide base pair is
changed, there are different categories of point mutations:
Silent Mutations - changing the base pair doesn't affect the amino acid sequence of
the polypeptide. For example, in the above DNA sequence, what happens when you
substitute a G for the marked A in the triplet TTA?
mRNA codon:
Amino acid:
Overall effect:
Missense Mutations - changing the base pair affects the amino acid sequence of the
polypeptide, possibly with direct, traceable effects in the individual. For example, in
the above DNA sequence, what happens when you substitute an A for the marked T
in the triplet GTT?
mRNA codon:
Amino acid:
Overall effect:
CHAIN TERMINATION MUTATIONS - changing the base pair creates a stop codon
where there shouldn't be one. For example, in the above DNA sequence, what
happens when you substitute a T for the marked G in the triplet ACG?
mRNA codon:
Amino acid:
Overall effect:

Aresearcher designed an investigation to test what effect eating different types of food would have on blood insulin levels. she selected 10 male subjects who were all 25 years of age and in good health. the experiment took place over 3 days. at 8: 00 a.m. on each day, the subjects ate a meal consisting of only 1 type of food. they had their blood insulin levels measured after consuming the meal. on day 1 they ate a high fat diet, on day 2 they ate a high protein diet, and on day 3 they ate a high sugar diel what is the independent variable in this experiment? a the age of the subjects b the blood insulin level c the type of food consumed d the time of day the meal was consumed
