The Meselson and Stahl's experiment provided conclusive evidence for the semiconservative replication of DNA in E. coli . What pattern of bands would occur in a CsCl gradient for conservative replication?
-After one generation in the 14N, there would be two bands, one heavy and one light (no intermediate).
-After the second generation in the 14N, there would also be two bands, one heavy and one light (no intermediate).
-After one generation in the 14N, there would be two bands, one heavy and one light (no intermediate).
-After the second generation in the 14N, there would be three bands, one heavy, one intermediate, and one light.
-After one generation in the 14N, there would be one heavy band (no intermediate and no light). After the second generation in the 14N, there would be three bands, one heavy, one intermediate, and one light.
-After one generation in the 14N, there would be three bands, one heavy, one intermediate, and one light. After the second generation in the 14N, there would also be three bands, one heavy, one intermediate, and one light

Which cluster of terms accurately reflects the nature of DNA replication in prokaryotes?
-random point of initiation, bidirectional, semiconservative
-random point of initiation, unidirectional, semiconservative
-fixed point of initiation, unidirectional, conservative
-fixed point of initiation, bidirectional, conservative
-fixed point of initiation, bidirectional, semiconservative

Identify a difference between the RNA polymerases of eukaryotes and prokaryotes.
-In eukaryotes, three polymerases (I, II, and III) have been identified; only one has been described in prokaryotes.
-In prokaryotes, three polymerases (I, II, and III) have been identified; only one has been described in eukaryotes.
-In eukaryotes, three polymerases (α, β, and δ) have been identified; only one has been described in prokaryotes.
-In prokaryotes, three polymerases (α, β, and δ) have been identified; only one has been described in eukaryotes.

Which of the following lists steps of mRNA production in eukaryotes in the correct order?
-Transcription, 5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane
-Transcription, 5' cap addition, addition of poly-A tail, passage through nuclear membrane, exon splicing
-Transcription, addition of poly-A tail, 5' cap addition, exon splicing, passage through nuclear membrane
-5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane, transcription

Once elongation is underway, tRNAs involved in the process occupy a series of sites on the complexed ribosome. The occupation of sites occurs in the following order.
-A Site, S Site, E Site
-A Site, P Site, E Site
-A Site, P Site, E Site, S Site
-P Site, E Site, A Site

Assume that a plasmid (circular) is 2800 base pairs in length and has restriction sites for EcoRI at the following locations: 400, 700, 1400, and 2600. Give the expected sizes of the restriction fragments following complete digestion with EcoRI.
-300, 700, 2200
-400, 1200, 1600
-300, 600, 700, 1200
-200, 400, 700, 1200
-700, 400, 1400, 2600

The following are four processes common to most cloning experiments:
i)transforming bacteria
ii)plating bacteria on selective medium
iii)cutting DNA with restriction endonucleases
iv)ligating DNA fragments
Place the components of this list in the order in which they would most likely occur during a cloning experiment.
-i, ii, iii, iv
-ii, i, iv, iii
-iv, i, iii, ii
-ii, iii, i, iv
-iii, iv, i, ii
