Bacterial Genetics

A bacterial genome is typically

a single circular DNA molecule.

Semiconservative DNA replication means that

each daughter DNA molecule is composed of one original strand and one new strand.

The bacterial chromosome is

both circular and found in a nucleoid.

The events of ________ are initiated at sequences called origins.

DNA replication

In conjugation, F+ cells

contain an F plasmid.

The process indicated by the arrow in Figure 7.1 represents

lagging strand synthesis.

Which of the following is found in both archaeal and eukaryotic genomes?

histones

Which of the following is found at the 5' end of a DNA strand?

a phosphate group

Typical eukaryotic genomes are composed of ________ chromosomes.

multiple linear

DNA is composed of four nucleotides, A, C, G and T. Each codon is composed of three nucleotides. The number of possible codons is

64.

RNA polymerase is primarily responsible for

transcription.

Which of the following is involved in translation?

mRNA, rRNA, and tRNA are all involved.

The horizontal transfer process known as transduction

involves a virus.

Genetic elements known as promoters are initiation points in the process of

transcription.

In generalized transduction, viruses carry random DNA sequences from one cell to another.

True

Amino acids are delivered in their appropriate order by

tRNAs.

Which of the following is characteristic of prokaryotic genomes but not eukaryotic genomes?

circular chromosomes

Which of the following causes mutations by creating thymine dimers?

ultraviolet light

Transfer of random pieces of DNA mediated by phage is known as

generalized transduction.

Prokaryotic operons typically include a(n) ________ and a(n) ________ with multiple genes.

operator; promoter
