<span>Nicotinic acetylcholine receptors (nAChR), are <span>ligand-gated ion channels and they can be a Na+, K+ and Ca2+ ion channel. Since nifedipine is a Ca2+ channel blocker (Ca2+ channel antagonist), it might inhibit the response of acetylcholine (if its receptor is Ca channel).</span></span>

Isolating all of the RNA out of an organism, subjecting it to reverse transcriptase, and then cloning all of the resulting DNA i
Lisa [10]

Answer:

The answer is C.

Explanation:

The example process given in the question is describing the creating of a cDNA Library. cDNA or Complimentary DNA is copy of the DNA that is taken from a messenger RNA (mRNA), which is what is done with the reverse transcriptase. And the process described as cloning the resulting DNA into plasmids is the part where the library is created. The resulting DNA is put into host organisms and stored there for further investigation or use.

I hope this answer helps.

An individual homozygous dominant for the thumb shape mates with an individual homozygous recessive for thumb shape. What are th
natulia [17]

Answer:

A punnet square can be described as a diagram which is made to check the outcomes of a cross.

To check the probability of the offsprings of a cross between homozygous dominant thumb shape parent with a homozygous recessive thumb shape parent, let's draw a punnet square:  

        t              t

T    Tt            Tt

T    Tt            Tt

The results of the punnet square depict that:

Genotype: All of the offsprings will be heterozygous for the thumb shape trait. Tt will be the genotype.

Phenotype: All of the offsprings will show the thumb shape like the thumb shape of the dominant parent.

Chymotrypsin
Georgia [21]

Answer: d. all of the above

Explanation:

Chymotrypsin is produced by the Pancreas and has the function of digesting proteins.It consists of three polypeptide chains connected by two inter-chain disulfide bridges. Chymotrypsin exerts an important biological function which is the hydrolysis of proteins in the small intestine. The cleavage of peptide bonds is selective, occurring only on the carboxyl side of aromatic side chains of tyrosine, tryptophan and phenylalanine, and large hydrophobic radicals such as methionine. Chymotrypsin also hydrolyzes ester
