BSC 108 Final Exam (Modules 9-12) Questions with
Detailed Verified Answers
What does DNA stand for? Ans: ✓ ✓ ✓ deoxyribonucleic acid
What is DNA composed of? Ans: ✓ ✓ ✓ nucleotide subunits
DNA has a sugar-phosphate backbone that is covalently bonded to a nitrogen-containing base.
What does this mean? Ans: ✓ ✓ ✓ it is made of a sugar called deoxyribose and a phosphate group
A DNA molecule contains ______ strands of DNA. Ans: ✓ ✓ ✓ 2
What do these 2 DNA strands form? Ans: ✓ ✓ ✓ a double helix
These DNA strands are __________. Ans: ✓ ✓ ✓ complementary
What are the nitrogen-containing bases? Ans: ✓ ✓ ✓ Adenine, Thymine, Cytosine, Guanine
What are the nitrogen-containing bases held to each other by? Ans: ✓ ✓ ✓ hydrogen bonds

What does cytosine pair with? Ans: ✓ ✓ ✓ Guanine
What does DNA do? Ans: ✓ ✓ ✓ stores genetic information which can be copied and passed from
generation to generation
What happens in the DNA replication process? Ans: ✓ ✓ ✓ one parent molecule that has 2
complementary strands separates. when they separate at the origin of replication, synthesis of 2
new complementary strands occurs in the replication bubble using the parent strands as templates
and the bubble merge as DNA replications progress in the 2 directions. each strand is used as a
template to make a new strand. each of the 2 daughter molecules will be composed of one "old"
parent strand and one "new" strand
What does DNA lead to? Ans: ✓ ✓ ✓ specific traits by dictating the synthesis of proteins
What is the structure of RNA? Ans: ✓ ✓ ✓ a single stranded nuclei acid. it contains uracil instead of
thymine. it contains the sugar ribose instead of deoxyribose
What are the 3 types of RNA? Ans: ✓ ✓ ✓ mRNA, tRNA, rRNA
What is the function of mRNA? Ans: ✓ ✓ ✓ to carry genetic info from the nucleus to the
ribosomes
What is the function of tRNA? Ans: ✓ ✓ ✓ acts as a molecular interpreter and carries amino acids,
matching them with codons in mRNA using anticodons
What is the function of rRNA? Ans: ✓ ✓ ✓ ribosomal RNA, carries out protein synthesis in
ribosomes
What do genes code for specific proteins with? Ans: ✓ ✓ ✓ transcription and translation
