This DNA Structure and Replication Sample Questions quiz assesses understanding of DNA's double-helical structure, replication mechanisms, and related genetic disorders. It is crucial for learners aiming to master genetic fundamentals and implications in human health.
3’ to 5’ DNA repair enzymes
3’ to 5’ DNA polymerase
Okazaki fragments
Replication and immediate crossover of the leading strand
Lack of RNA primers on one of the strands
Rate this question:
All hydroxyl groups of pentoses are involved in linkages
Bases are perpendicular to the axis
Each strand is identical
Each strand has parallel, 5’ to 3’ direction
Each strand replicates itself
Rate this question:
DNA-directed DNA polymerase
Unwinding proteins
DNA polymerase I
DNA-directed RNA polymerase
DNA ligase
Rate this question:
Half should contain no radioactivity
All should contain radioactivity
Half should contain radioactivity in both strands
One should contain radioactivity in both strands
None should contain radioactivity
Rate this question:
Each discontinuous piece making up the chromosomes of eukaryotes is about the same size as each prokaryotic chromosome
Unlike bacterial DNA, no histones are associated with it
It is not replicated semiconservatively
It is a linear and unbranched molecule
It is not associated with a specific membranous organelle
Rate this question:
RNA primer is synthesized
DNA polymerase III synthesizes DNA
Helicase (rep protein) continuously unwinds duplex DNA at the replication fork during synthesis
Nucleoside monophosphates are added in a 5’ to 3’ direction along the growing DNA chain
DNA ligase repeatedly joins the ends of DNA along the growing strand
Rate this question:
Primase
DNA ligase
DNA gyrase
RNA polymerase III
Reverse transcriptase
Rate this question:
The DNA polymerase uses an RNA primer but does not degrade it
The DNA polymerase contains an RNA molecule that serves as template for DNA synthesis
The DNA polymerase must cross-link the 5’ and 3’ termini
The DNA polymerase has a subunit that facilitates binding to repetitive DNA
The DNA polymerase does not use an RNA template or primer
