Sickle cell anemia is a monogenic disorder in which the body produces abnormally shaped red blood cells. Sickle cell anemia is inherited in an autosomal recessive pattern. A person who is a carrier for this disease typically do not show signs and symptoms of the condition. Two cousins in Bangladesh got married and had kids without being aware that sickle cell disease runs in their family. Laboratory testing later showed that both partners were carriers for the sickle cell mutation. If this couple decides to have children, What is the chance (probability) that their children will also be carriers of the sickle cell disease?

Answers

Answer 1

Answer:

there's a ½ or 50% chance of their children will also be carriers of the sickle cell disease.

Explanation:

let IA = normal and IS =sickle cell

since both parents are carriers so it would be IAIS x IAIS

IAIS x IAIS

1 IAIA, 2 IAIS, 1 ISIS

Stem cells can be developed into a required tissue because of their ability of cellular DIFFERENTIATION. These cells can develop specialized cells.

Stem cells are cells that can develop into specialized types of cells in order to perform specific functions.

The process of cellular differentiation from stem cells involves differential gene expression patterns, a cellular process that leads to the development of distinct types of cells.

For example, hematopoietic stem cells express specific genes (e.g., the hemoglobin gene) in order to differentiate into mature red blood cells that function to trasnport oxygen to all body cells.

A cross country runner runs 8 km in 2 minutes. What is his speed?

Answers

The speed of the cross country runner is equal to 4 km/min.

Given the following data:

Distance = 8 km.Time = 2 minutes.

To determine the speed of the cross country runner:

Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Speed = \frac{8}{2}[/tex]

Answers

Answer:

D. Hydrolysis

Explanation:

Dehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case.

I hope this helps have a great day :)

The process that breaks down nucleic acids into nucleotides is hydrolysis. The correct option is d.

What is hydrolysis?

Any chemical reaction in which a water molecule breaks one or more chemical bonds is known as hydrolysis.

When water is the nucleophile, the phrase is used generically to refer to substitution, elimination, and solvation processes.

Nucleo depolymerase is another name for nuclease. By cleaving the phosphodiester bond that connects the nucleotides in the nucleic acids, the nucleic acid is broken down into nucleotides.

Either an enzyme or a non-enzyme can cleave the nucleic acid chain. Since the initial step in the alkaline hydrolysis of a polynucleotide is the transfer of the bond from C5' of the subsequent nucleotide to C2' of the same nucleotide, a 2'-OH group is necessary.

Thus, the correct option is d.
