all of these answers are correct

The chromosome of a prokaryote is?

circular

Which of the following enzymes adds DNA nucleotides to existing strands of DNA, perhaps just before cellular division in a prokaryote?

DNA Polymerase

___ is the conversion of DNA to mRNA, while ______ is the process of using mRNA to create a protein.

transcription, translation

Which of the following is a single stranded nucleic acid?

mRNA

What type of bonds connect the base pairs in DNA?

double stranded, hydrogen bonds

Which sequence is most likely to be found in mRNA?

UAAUAGCUCGA

The anticodon on a tRNA

binds complementarily to mRNA at the ribosome

A gene within a prokaryote contains damaged DNA. Two thymines have formed a dimer and are stuck together side-by-side. What most likely caused this kind of DNA damage?

UV radiation

DNA stores information regarding how to make proteins, but where is the information stored to make carbohydrates and lipids?

The DNA stores information used to make enzymes and other proteins that work together to help make carbohydrates and lipids.

In coll, the Lac operon regulates the metabolism of lactose. In the absence of lactose, the repressor protein binds to preventing

the operator, RNA polymerase from transcribing the Z. Y, or A genes

would metabolize lactose when needed, but waste energy making proteins to metabolize lactose when lactose is absent

During DNA replication, what is the role of DNA polymerase?

makes very few errors, making most daughter cells after replication identical.

Which of the following processes is an example of vertical gene transmission?

binary fission

What process involves DNA fragments from dead bacteria entering a living bacterium and recombining with its DNA?

transformation

Which of the following would generate a recombinant bacterium?

Putting a gene from a jellyfish that makes a green glowing protein into a bacterium

During transduction __ carry. ___ from one bacterial cell to another.

viruses, small genes or parts of genes

Which of the following might be able to cut DNA on a plasmid?

restriction enzyme
