2024 AP Biology Final Questions and
Answers
The SRY gene
✓ ~~~is a gene found on the Y chromo that codes for male development
X Inactivation
✓ ~~~one of two X chromosomes is randomly inactivated and remains coiled as a Barr body
If there is 15% adenine in a cell, what is the percentage of cytosine?
✓ ~~~35%
5' to 3' and 3' to 5' means that DNA is

I can use a mRNA genetic code table to transcribe and translate a gene into an
amino acid sequence.
✓ ~~~should be true
Central Dogma
, ✓ ~~~DNA -> RNA -> Protein
Meiosis
