,The two polynucleotide chains in DNA are held together primarily by H bonds between A and U
as well as between G and T?
a. True
b. False - ANS B
(DNA does not have Uracil, it has Cytosine)
K
If there is 12% of A in a DNA molecule, then the % of G must be?
a. 12%
C
b. 30%
c. 368
d. 76%
LO
e. none of these are correct - ANS E
(A=T and C=G, A+G/T+C=1)
The catalytic molecule responsible for making a peptide bond during translation (protein
YC
synthesis) in cells is?
a. amino synthase
b. ribozyme
c. release factor
d. plasmid
D
e. none of these - ANS B
Which of the following biotechnology procedures would one use to specifically edit a known
U
sequence of DNA in a genome?
a. polymerase chain reaction
ST
b. restriction endonuclease
c. CRISPR-Cas9
d. reverse transcriptase
e. none of these is correct - ANS C
The genetic code?
a. is redundant
b. is universal
c. exhibits 'wobble'
d. is a triplet codon
, e. all of the above - ANS E
The number of human protein genes is closest to which of the following numbers?
a. 100,000
b. 3,000,000
c. 20,687
d. 40% of all human DNA
e. none of these - ANS C
K
Which of the following processes is NOT part of the Central Dogma?
a. transcription
C
b. translation
c. synapsis
d. replication
LO
e. all of these - ANS C
(Central Dogma: Replication, Transcription, Translation)
The enzyme that opens/untwists DNA to allow for it replication by DNA polymerase is?
YC
a. topisomerase
b. helicase
c. primase
d. DNA ligase
e. binding proteins - ANS B
D
(Topoisomerase = removes supercoils, Primase = RNA polymerase, DNA ligase = seals 3' open
holes, Binding proteins = stabilize replication fork)
U
Which of the following enzymes of DNA replication is actually an RNA polymerase?
ST
a. topisomerase
b. helicase
c. primase
d. DNA ligase
