1. The DNA sequence located near the oriC site that gets pull towards the poles of the cell to ensure that each daughter cell receives one copy of the genome.
2. The protein that ParA ATPase will directly interact with.
3. Attaches the anchored form of the microbe to a surface.
4. The protein that ParA ATPase will pull the protein-DNA complex towards.
5. Caulobacter
6. The end of the cell that does not develop a stalk or flagella (coincidentally the new pole formed during cell replication).
7. The genome.

QUESTION 4

1. Which of the following proteins could help fold a protein secreted into the periplasmic space?

DnaK
Rho
GroEL
SecA

QUESTION 8

1. During protein synthesis, ______  is the first amino acid to enter the ribosome. The first amino acid is loaded in the  _____site of the ribosome. All other amino acids enter the ribosome in the _______  site.

A peptide bond is formed between the amino acid that entered the ribosome in the  _____ site and the amino acid in the  _____ site that has the peptide chain hanging off of it.

QUESTION 12

1. DNA in a prokaryotic cell is localized in the  _____ region of the cell. The genome is organized into   _____which experience  _____ super-coiling to tightly package the DNA. The exception to this is hyperthermophilic bacteria which use _____  super-coiling to produce a more stable, tightly packeged, molecule of DNA capable of surviving higher temperatures. The _____  of the genome are anchored by _______ , so that if one region of the genome is unwound due to damage, only that domain is damaged.

The enzyme _______ , also known as Topoisomerase II, creates negative supercoils by introducing a double-strand break in the DNA. This enzyme also relaxes DNA supercoils introduced during DNA synthesis by the enzyme ___________.

QUESTION 14
