enot [183]

Answer:

This question lacks options, options are:

A) histamine

B) gastrin

C) secretin

D) ACh

The correct answer is C.

Hormones or paracrines that inhibit gastric secretion include <u>secretin </u>.

Explanation:

Hormones pass into the blood that waters the digestive system, go to the heart, circulate through the arteries and return to the digestive system, where they stimulate the production of digestive juices. The hormones that control digestion are gastrin, secretin and cholecystokinin. Secretin is stimulated by intestinal acid at the duodenal level. Its effect inhibits gastric acid secretion, prostaglandin secretion and via somatostatin release. It decreases gastric emptying and stimulates bile and pancreatic bicarbonate secretion.

Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3' Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3' The two primers above have the melting
CaHeK987 [17]

Answer:

Short answer is primers are partially complementary.

Explanation:

Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3'

Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3'

When we write reverse primer 5' to 3' we can easily see that

3'-TTGGCCAATGG---5' is complementary to the forward primers'

5'---AACCGGTTACC-3' sequence. So instead of binding to the template DNA these primers might bind each other resulting with reduction of efficiency of DNA amplification.
