Molecular Biology Midterm Exam 1 2025
Griffith's experiment - Correct Ans-genetic material could be transferred between dead
bacteria and living bacteria

Avery, McLeod and McCarty - Correct Ans-Proved that DNA is the hereditary material.
DNase, Protease, RNase experiment

Hershey-Chase Experiment - Correct Ans-confirmed that DNA is the genetic material
because only Phosphorous radiolabeled DNA could be found in bacteriophage-infected
bacteria (in the pellet) versus the radioactive sulfur labeled protein coats in the
supernatant

Structure of nucleotides - Correct Ans-5 carbon sugar, phosphate group, nitrogenous
base. Phosphate and sugar linked by phosphodiester bonds, bases by H bonds

Purine - Correct Ans-Adenine and Guanine, 2 ring

Pyrimidine - Correct Ans-Cytosine and Thymine, 1 ring

Differences between DNA and RNA - Correct Ans-RNA contains uracil
DNA contains thymine
DNA has deoxyribose

other roles of nucleotides - Correct Ans-electron carrier, methyl carrier, and for
signalling (e.g. NAD+, NADP+, FAD, adoMet, cAMP)

DNA structure - Correct Ans-double stranded, antiparallel, helical, with a major and a
minor groove.

helix of DNA - Correct Ans-10.5 bp per turn in B form DNA, with each bp being 3.4
angstrom or 1/10 nm apart.

B-form DNA - Correct Ans--the most common form of DNA in which molecular

Molecular

, Molecular


A-tracts - Correct Ans-sequences of 4-6 As or Ts seperated by Gs and Cs, repeated.

transcription factors

Inverted repeats - Correct Ans-sequence followed by sequence that is its inverted
repeat. form hairpin or cruciform structures.

palindrome - Correct Ans-Same sequence on both strands read from 5' to 3' direction.
restriction enzyme binding site.

RNA structure - Correct Ans-usually A form helix. can form non-typical bps e.g. A-A and
G-U. 2'OH allows for more complicated secondary structures. Also can become
riboswitches

Denaturation - Correct Ans-breaking of H bonds between strands of DNA at high pH or
Temperature

Annealing - Correct Ans-strands reattach together at neutral pH and temp

heteroduplex - Correct Ans-a DNA double helix composed of single strands from two
different DNA molecules. used as molecular genetics tool for comparing sequence
similarity (northern and southern blotting)

northern blotting - Correct Ans-DNA-DNA interaction (as ssDNA)

southern blotting - Correct Ans-ssRNA transcript, ssDNA interaction.

deamination - Correct Ans-loss of an amino group, e.g. Cytosine deaminated to Uracil.
lots of cytosine deaminated but repaired.

Methylation - Correct Ans-addition of a methyl group, most often on C and A. makes
DNA more compact, roles in DNA repair, and restriction-modification systems.

RNA methylation - Correct Ans-at 2' OH, interferes with the extra bonds that it could
otherwise form.

RNA acetylation - Correct Ans-tend to occur in tRNAs and rRNAs, etc. e.g. acetyl
cytidine, inosine, pseudouridine

cloning steps - Correct Ans-1) select cloning vector
2) isolate DNA to clone
3) join vector and DNA fragments
4) introduce recombinant vector to host
5) use selective pressure to favor recombinant hosts
