Homework Answers
I believe the correct answer to be:
Option C) holoenzymes formed by sigma and RNA pollmerase.
As holoenzymes are the functional part of an enzyme and are capable of performing its function on its own.

QUESTION 22 These cell wall proteins allow many bacteria to adhere tightly to host cells, colonize, and resist flushing. This is used as a virulence factor by Bordetella pertussis, Helicobacter pylori, and Streptococcus pneumoniae, and Neisseria gonorrhoeae. This best describes what? Bacterial flagella and axial filaments. Bacterial cell surface proteins called adhesins. Bacterial capsules (glycocalyces). Bacterial invasions Bacterial pili.

Scientists have engineered bacteria to produce human proteins such as human growth hormone (hGH) to help treat dwarfism. Suppose the unmodified eukaryotic gene coding for hGH is inserted directly into a bacterial chromosome. Select the reasons why no expression would be seen in the bacterial cell for the hGH gene. Bacteria cannot remove intronic sequence from a gene, so if the gene for hGH were transcribed, it would translate to a nonfunctional protein. The bacterial nucleoid does not have the...

Question 1 0.5 pts It has been shown that inhibition of a key chromatin remodeling complex known as NURD. by deleting one of its subunits, can result in a significant increase in the efficiency of reprogramming of somatic cells into pluripotent stem cells. The reprogramming is normally done by the induced expression of a battery of transcription factors in the somatic cells, but is typically not very efficient. Such an observation suggests that the NURD complex is normally...

QUESTION 1 George Beadle and Edward Tatum performed an experiment in which they made single-gene mutations in the bread mold Neurospora crassa. These mutations resulted in several Neurospora auxotrophs. Further analysis revealed specifically how the mutations affected synthesis of the amino acid in question. What was the significance of these results? A single gene encodes a single protein, in the case of this experiment, an enzyme. Enzymes are needed to synthesize amino acids. They showed that mutations are heritable. They...
