Analyze how a point mutation can affect the overall protein shape and function, using hemoglobin as an example.
aniked [119]

Answer:

A point mutation can be described as a mutation in which changes occur in a single nucleotide. A nucleotide may get changed, deleted or inserted from the sequence of DNA. Point mutations can be harmless or harmful depending on the nucleotide in which the changes occur.

A change in just one nucleotide can result in the formation of wrong amino acid and hence changed or wrong proteins can be formed. If the original protein was involved in cellular reproduction, then the entire process of reproduction can be affected by a point mutation.

Sickle- cell anaemia is a disease in which the body fails to produce enough healthy red blood cells. This disease occurs due to point mutation. Point mutation occurs where glutamine (GAG) of the β-globin gets changed into valine (GUG). This change causes the haemoglobin to get a deformed structure due to which it is not able to carry out oxygen.

Which reflex is triggered by food in the stomach, relaxes the ileocecal valve, and allows residue into the cecum?
kari74 [83]

Gastroileal reflex is triggered by food in the stomach, relaxes the ileocecal valve, and allows residue into the cecum.

The gastroileal reflex is triggered by the presence of food in the stomach as well as gastric peristalsis.

Gastroileal reflex brings about peristalsis in the ileum as well as the opening of the ileocecal valve, which in turn facilitates the emptying of the ileal constituents into the large intestine or colon.

The gastroileal reflex is one among the three extrinsic reflexes of the gastrointestinal tract. The other two include the gastrocolic reflex as well as the enterogastric reflex.

This type of gastrointestinal reflex is moderated by the vagus nerve and gastrin.
