Chromosomes, Mitosis And Dna

Chromosomes convey genetic data in a molecule called DNA. A sort of cell division called mitosis ensures that when a cell divides each new cell created has the same genetic data. DNA exists in a cell`s nucleus inside structures called chromosomes. Each section of a chromosome that contains the code for the creation of a specific protein is known as a quality.

Every chromosome is produced using a single molecule of DNA, however when a cell is prepared to separate, the DNA copies itself, then, at that point, coils and condenses to shape the chromosomes that we see in micrographs. Every human body cell contains 46 chromosomes. These can be set up into 23 pairs. Every chromosome in a couple carries the same types of genes. The 23rd pair are the sex chromosomes:

In females, the two chromosomes are indistinguishable in shape. There are two X chromosomes. Females are alluded to as XX.

In males, one of the chromosomes is an alternate in shape. There is a X and furthermore a Y chromosome. Males are alluded to as XY.

Mitosis

Cells divide when:

an organism develops

an organism becomes harmed and needs to create new cells

It is fundamental that any new cells delivered contain genetic data that is indistinguishable from the parent cell. A developing and partitioning cell goes through a progression of stages called the phone cycle. The primary phases of the cell cycle include cell development, then, at that point, the production of DNA. The single strand of DNA that makes up every chromosome creates a precise of itself. The phone goes through a sort of cell division called mitosis. In mitosis, two cells called little girl cells are created, each indistinguishable from the parent cell.
