Structure of chromosome

Answer 1

Chromatin are a network of irregular,thin,thread-like fibres present in the nucleoplasm of the nucleus. When the cell division occurs, then these fibres(irregular) change to chromosomes(with a definite shape like that of an open scissors).

Answer 2

Chromosomes are structures within cells that contain genetic material in the form of DNA. Each chromosome consists of a long DNA molecule wound around proteins called histones. The DNA in a chromosome carries genes, which are the instructions for building and maintaining an organism. Chromosomes come in pairs, with one inherited from each parent, and are organized into different regions such as telomeres, centromeres, and chromatin.

Answer 3

The chromatin packages the DNA to a smaller sizes to fit in a cell for the DNA to be strengthen to go through meiosis and mitosis. The chromatin also controls the expression of the genes and the replication of DNA.

Answer 4

the chromatin is what transforms into the chromosomes. Chromosomes then duplicate themselves so that the cell can multiply and become 2 or 4 depending on what type of cell. SEP

Answer 5

Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Answer 6

It has a dense threadlike and rodlike structure.

Answer 7

During cell reproduction, chromation coils up into structures

Answer 8

Chromatin is found in the nucleus as fibers. When these fibers coil up they form chromosomes.

Answer 9

protein(histone) and DNA
