How could stem cells prove helpful in the treatment of cardiovascular diseases

Answers

Answer 1

Answer:

Stem cells are self-renewal undifferentiated cells present in the human body. Undifferentiated means that they can divide and differentiate into many cell types of the body depending upon the differentiating potency of the stem cell.

If scientists could regulate the process of differentiation, they can able to differentiate a stem cell into a cell type of interest such as cardiac cell.

These cells are then can be used to replace the damaged or dead cells present in the body.

Thus, it can help in the treatment of diseases such as cardiovascular disease.

Answer 2

Answer:

stem cell can differentiate to form heart muscle cells.

Answers

a. is continuous in two directions until the whole chromosome is copied.

The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size.

10. How is it that a code consisting of only four letters (A, T, G, C) can contain instructions for all the different parts of an organism and account for the diversity of organisms on this planet?

Answers

Answer:

The response for this question: How is it that a code consisting of only four letters (A, T, G, C) can contain instructions for all the different parts of an organism and accout for the diversity of organisms on this planet, would be: These letters, known as nucleotide bases, when paired together, can each code for a wide variety of amino acids, the building blocks of proteins. It is proteins that carry out the instructions that are written in the genetic code and each amino acid in a protein can be coded for by more than one of the organized nucleotide pairings.

Therefore, during the process of translation, meaning DNA-RNA-protein, although the nucleotide pairings are pretty basic and limited, each of them, when interpreted by ribosomes and their accompanying tRNA, will call in different types of amino acids and build different types of proteins, depending on the need, the purpose and the location where these proteins will have to act.

This is how from a limited group of DNA nucleotide pairings, it is possible to have so many differences not only within the same organism, but among all living organisms that exist.

the DNA codes contain different combinations
