DNA replication is semiconservative, which allows each of the 2 strands to serve as a
template for the new strands - ANSWER true
Recall that the DNA polymerase must bind a double-stranded polymer before it can
start making its own DNA polymer. What helps the DNA polymerase to overcome this
problem in DNA replication? - ANSWER RNA primers
Several components of cigarette smoke, including benzopyrene, insert themselves into
the DNA and lead to several types of mutations such as frameshift mutations, including
both insertions and deletion. Which repair pathway would be used to repair this type of
damage? - ANSWER Nucleotide Excision Repair
Maternal smoking during pregnancy is hazardous yet common in many places. Many
studies have associated prenatal smoking to unhealthy physical and psychological
outcomes for the baby. Researchers know that maternal smoking affects are epigenetic
in nature. Which event can be considered epigenetic in nature? - ANSWER Changes in
chromatin structure
Blood is what type of inheritance? - ANSWER codominance
What is the probability that a child will have an autosomal dominant disease if their
father is heterozygous for the allele and their mother is homozygous for the normal
allelle? - ANSWER 50%
