During DNA replication,
a. DNA polymerase is blocked by methyl groups, and methylated regions of the genome are therefore left uncopied.
b. methylation of the DNA is maintained because DNA polymerase directly incorporates methylated nucleotides into the new strand opposite any methylated nucleotides in the template.
c. methylation of the DNA is maintained because methylation enzymes act at DNA sites where one strand is already methylated and thus correctly methylates daughter strands after replication.
d. all methylation of the DNA is lost at the first round of replication.
e. methylated DNA is copied in the cytoplasm, and unmethylated DNA in the nucleus.
What would happen if you had a mutation that prevented the inclusion of exon 2 in the tra protein of Drosophila?
a. Genetic females would become males, and genetic males would become females.
b. Genetic males would become females.
c. Genetic females would become intersex flies.
d. Genetic females would become males. e. Genetic males would become intersex flies.
