which of the following statements provided the evidence for you to rule out the possibility that morgan had lyme disease or flu?

A researcher is studying gene expression in different types of cells. For a gene of interest, he notes its expression no longer appears to be regulated—it occurs in all cells, rather than in just a few cell types. The gene’s corresponding transcript and protein, however, appear normal. This may be the result of a mutation in which of the following regions associated with the gene? (5 POINTS)Silencer

Intron

Exon

Promoter

9What role does the MutL protein play in DNA repair? (5 POINTS)

It performs a proofreading function, similar to DNA polymerase, and removes incorrect bases from the template DNA strand.

It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.

It recognizes the newly-synthesized DNA strand (e.g., by detecting nicks), ensuring only it—and not the template strand—is repaired.

It helps to link together regions of DNA, after an error has been removed via exonuclease.

10If a mutation occurs that affects the large subunit of a ribosome, rendering it inactive, how would this affect translation? (5 POINTS)

The small subunit of the ribosome would fail to associate with a mRNA.

Methionine tRNA would not recognize the start codon of a mRNA.

New amino acids would not be added after the initial methionine, so translation would be effectively inhibited.

Arginine tRNA, rather than methionine tRNA, would associate with a mRNA’s stop codon.

Sometimes the reflex response is diminished or absent- a phenomenon termed hyporeflexia. Do you think hyporeflexia would be caused by disorders of the central nervous system or the peripheral nervous system? Explain your reasoning.

The subshell designations follow the alphabet after f. what is the first shell in which an h orbital would be allowed?

Rosiglitazone is an antidiabetic drug meant to target adipose cells, enhancing insulin effects. The drug mimics the fatty acid metabolites that bind to a nuclear receptor found mostly in fat, liver, and a few other tissues. Cortisone is a type of glucocorticoid mimic that binds to a nuclear receptor, activating the receptor's transcriptional regulatory function. The ligand-activated receptor binds coregulatory proteins, and the protein complex targets gene transcription involved with inflammation. Which of the following statements about these two drugs best describe their mechanism of action? Choose one or more: A. Rosiglitazone will bind to its receptor (peroxisome proliferator-activated receptor), and the receptor- B. Zinc fingers bind at the top of rosiglitazone receptor dimers as a stabilizer, allowing the alpha helical C. Receptor dimers with bound cortisone bind to the DNA target using a zinc finger to bind to an inverted D. Cortisone and rosiglitazone form heterodimers with the receptor in a head-to-tail fashion to regulate ligand complex can bind to the RXR receptor in a head-to-tail fashion. recognition strand to bind into the minor groove of the target DNA. repeat that must be at least partially palindromic to be recognized. gene activity.
