The galactosemia is a condition, in which the affected person is not able to metabolize the galactose sugar. This is a genetic disorder, inherited as an autosomal recessive trait. The homozygous dominant and the heterozygous individual do not show this condition. Only the individuals having homozygous recessive trait will show this condition.  

Lets say allele G codes for galactosemia, and G codes for the dominant allele, and g code for recessive allele.

The attached image shows the possible pedigree of the Justin’s family.

What would happen if you delete one amino acid in a particular protein?
Karo-lina-s [1.5K]
It depends upon the protein and also where the deletion of the single amino acid has occurred. Does ur alter or disrupt an important fundamental function or aspect of the protein such as the capability of substrates to bind to the active site, or is near a region that is primarily for developing the additional structure of the protein and is not as important. In most cases, a single amino acid change will not cause the protein to lose its complete function of be denatured.

Shalnov [3]

True

Changes in the transcription of mRNA or the translation of a polypeptide are not considered to be mutations because they are not permanent changes to the cell.

Explanation:

The half-life of mRNA and proteins is short. mRNA has an average of 10 hours of life span while proteins have an average of  several days. Therefore mutation in these biomolecules will only persist as long as this mutated mRNA of protein exists. After its life-span, the molecule is degraded and replaced by a non-mutated mRNA or proteins. This is because the piece of DNA that codes for the mRNA and subsequent protein is not mutated. A mutation on DNA is the permanent kind of mutations because DNA is a highly stable molecule that stores information about the cell.

Explain the digestion process of a complex carbohydrate by arranging the statements in the order that they occur.
andreyandreev [35.5K]

Answer: The question is incomplete because the options are not given, here are the options from another websites.

A.The enzyme, amylase. which is present in saliva breaks potysaccharide chains into disaccharides.

B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides.

C. You take a bite and to chew the complex carbohydrate into smaller pieces.

D.Amylase is deactivated by the low pH in the stomach.

E.. Monosaccharides are absorbed through the intestinal wad.

The correct order are,

C. You take a bite and to chew the complex carbohydrate into smaller pieces.

A.The enzyme, amylase. which is present in saliva breaks potysaccharide chains into disaccharides.

D.Amylase is deactivated by the low pH in the stomach.

B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides

.E. Monosaccharides are absorbed through the intestinal wad

Explanation:

Carbohydrates are complex or large molecules are they are found in rice, bread e.t.c

Digestion of carbohydrates start from the mouth through a process called mastication i.e chewing of the carbohydrates. The salivary gland then secrete the salivary amylase which act on the chewed carbohydrates. The salivary amylase breaks down amylose and amylopectin present in starches into smaller chains of glucose which is called dextrins and maltose. When it get to the stomach, the amylase cannot further break it because it does not work in acidic conditions. The substance form chyme in the upper stomach and pancreatic enzymes act on it to break it down into simple sugar glucose. The pancreatic enzymes include sucrase, maltase and lactase.

Sucrase breakdown sucrose into glucose and fructose, maltase breakdown maltose in two molecules of glucose and lactase breakdown lactose into galactose and glucose. The simple sugar are then absorbed into the blood through the intestinal wall.
