hydro- gen bonding during replication, transcription, or translation. Which
of the fol- lowing pairs of molecules are complementary? (Select all that
apply): Answer- tRNA and mRNA
mRNA and template DNA
2. During DNA replication the parent strands and DNA poly-
merase .: Answer- separate, creates the new DNA strands

SNCA gene that codes for alpha-synuclein, a protein found in the brain.
5' ATGCGGTGACGG 3' Which of the following is the complementary
second DNA strand?: Answer- 5' CCGTCACCGCAT 3'

8. Beta thalassemia is a disease that causes low levels of hemoglobin. To
inherit this autosomal disease, an individual must receive two mutant
alleles. Which of the following likely represents the chromosome pairs of a
healthy parent who has a child with beta thalassemia? (The yellow band
represents the mutant allele and the green band represents the normal
allele.) *: Option 3- The chromosomes of a healthy parent who has a
child with beta thalassemia must be a carrier of the disease, i.e. the
parent must have one copy of the (dominant) normal allele and one
copy of the (recessive) mutant allele.
