Answer:

d. Placental hormones are antagonistic to insulin, resulting in insulin resistance.

Explanation:

The placenta secretes many hormones out of which estrogen, progesterone, and human placental lactogen have an antagonistic effect on insulin. Insulin from the pancreas triggers the uptake of glucose by cells and lowers down the blood glucose level. Increased secretion of estrogen, progesterone, and human placental lactogen during late pregnancy by the placenta makes the cells non-responsive or reduces their sensitivity to the presence of insulin. This is called insulin resistance.

When cells do not respond to the presence of insulin by taking up the glucose, the blood glucose levels are increased. This effect increases the availability of glucose to the fetus as the circulating glucose is transported to the fetus.

You've discovered a gain-of-function mutant E. coli strain that makes red colonies on plates containing normal minimal medium; w
Komok [63]

Answer:

The correct answers are options

B. "Sequencing reagents, such as dNTPs, ddNTPs, and DNA polymerase".

C. "A computer to blast the base pair sequence of the bacterial genomic insert against the genome sequence of your E. coli strain".

F. "An E. coli genomic library made from the mutant strain".

I. "A sequencing primer that hybridizes adjacent to the insertion site of the bacterial genomic fragment in the library plasmids, and pointing in the 5'-to-3' direction towards the bacterial genomic DNA insert".

Explanation:

Plasmid library transformation approaches are very useful to characterize novel mutant bacterium strains. In order to perform a characterization study of this kind, several reagents and tools are needed, including:

- "Sequencing reagents, such as dNTPs, ddNTPs, and DNA polymerase". One important part of knowing what makes novel mutant bacterium different is to sequencing its DNA.

- "A computer to blast the base pair sequence of the bacterial genomic insert against the genome sequence of your E. coli strain". BLAST is a useful computer tool that compares and aligns DNA sequences, this allows to detect what are the nucleotides that are unique in the novel mutant bacterium.

- "An E. coli genomic library made from the mutant strain". Once DNA has been sequenced, an genomic library must be constructed to ensure that this novel mutant is preserved.

- "A sequencing primer that hybridizes adjacent to the insertion site of the bacterial genomic fragment in the library plasmids, and pointing in the 5'-to-3' direction towards the bacterial genomic DNA insert". Sequencing primers are needed when new genomic libraries are constructed. This short DNA sequences allow DNA polymerase to synthesize the DNA an replicate the genome of interest.
