DNA fragments make the lines on an electrophoresis gel.

Fragments of DNA from each sample are placed each placed in a different well/slot.

A current is then run through the gel. The DNA migrates through the gel towards the positively charged side because DNA fragments are negatively charged.

The smaller fragments travel farther because they travel through the gel more easily (as seen in the picture from Encyclopedia Britannica).

Fragments of the same size group together at different areas of the gel making those lines.

Hormones or paracrines that inhibit gastric secretion include ________.
const2013 [10]

The correct answer is: D) secretin

Gastric secretion is highly regulated whether its secretion should be increased (when food is eaten) or decresed (as the stomach empties). Secretion is controlled by the nervous system and endocrine system that work together. There are three phases of gastric secretory control:

Cephalic-by the brain

Gastric-by the stomach itself

Intestinal- by the small intestine

All of three can work simultaneously.

Secretin is released by duodenal enteroendocrine cells and it stimulates the pancreas and gall bladder, but also suppresss gastric secretion and motility. Secretion of the secretin is stimulated by the chime and it is the part of intestinal phase.

Genes that are close together in the same chromosome:_________
Pepsi [2]

Answer:

C. tend to be transmitted together.

Explanation:

Independent assortment of alleles of the genes during anaphase-I of meiosis-I requires that the genes should be present on different chromosomes. The genes that are present on the same chromosomes deviate from the independent assortment. These closely placed genes are called linked genes. They move from one generation to next together and do segregate randomly. This results in the generation of more proportion of the parental types in the progeny. The linked genes may be present on both autosomes and sex chromosomes.
