BioChem C785 - WGU - Module 1 - all
questions and explained answers
, DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the
new strands - 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? - 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? - 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? - Changes in chromatin structure
Blood is what type of inheritance? - 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? - 50%
What is the complementary DNA strand for the DNA sequence 5'-ATT CGG GCT CCC - 3' - 5'- GGG AGC
CCG AAT - 3'
A research scientist is trying to create a new strain of bacteria that can produce a protein needed for her
research. What molecule will act as a template in creating the new protein? - messenger RNA (mRNA)
What is 1 direct effect of inhibiting translation? - the production of proteins would stop
