Exam 13: Bacterial Genome Replication and Expression

Which of the following is the initiator codon?

A bacterial cell that secretes proteins by types II and V systems is most likely Gram-negative.

In terms of relatedness to a specific cellular process,which protein does not belong with the others?

The genetic code is said to be __________ because more than one codon will specify a particular amino acid.

The Tat and Sec pathways are protein translocation systems.

Hershey and Chase demonstrated that when the bacteriophage T2 infected its host cell,the __________ is injected into the host but the __________ remained outside.

Which modification of the terminator region of a gene would specifically prevent rho-independent termination?

The Y-shaped part of the DNA molecule where the actual replication process occurs is called the replication __________.

When a DNA molecule is replicated,the daughter molecules contain one strand of parental DNA and one strand of newly synthesized DNA; this is called __________ replication.

In __________,ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.

If you wished to design an antimicrobial agent that prevented the formation of the 70S initiation complex in bacterial translation,which molecule should be specifically be targeted?

The B form of the DNA double helix contains a wider major groove and a narrower minor groove because the two polynucleotide strands are not positioned directly opposite one another in the helical cylinder.

Bacteria with DNA described as having "hairpin ends with inverted repeats" must not have circular chromosomes.

Some microbial proteins are spliced after translation in a reaction that results in removal of one or more internal intervening sequences called exteins.

Which of the following is in the coding region of a gene?

In order to add a single amino acid to a growing polypeptide chain,a total of __________ molecules or ATP of GTP are utilized.

How were experiments done by Griffith similar to those done by Avery,MacLeod,and McCarty?

The portion of the tRNA molecule that binds to the codon on the mRNA is called the

Choose the description below that best matches the current model of RNA polymerase holoenzyme.

The strand of DNA for a particular gene that is copied by the RNA polymerase to form mRNA is called the __________ strand.
