Question

Where are chromosomes found in a cell? State their function.

Answer 1

Hint: chromatin granule material condenses to make thread-like structure throughout the biological process known as chromosomes. They contain info to pass from one generation to the other. They're used as a blueprint.

Complete answer:
The chromosomes are found within the nucleus of a cell. At totally different stages of the biological process, cells show structured chromosomes in situ of the nucleus.
Chromatin contains polymer and a few basic proteins known as histones and a few non-histone proteins, and RNA in addition.
A single human cell has a polymer length of two metres that is equally distributed among the forty six chromosomes. Each body contains a primary constriction known as the centromere, a circular structure.
On the edges of the centromere a disc formed structures known as kinetochores are present.
Chromosomes have the subsequent functions -
Regulation of cellular proteins.
Contains genetic info to manage cellular activities.
Contains genetic info to develop the fundamental characteristics of the offspring.
Contains info for the assembly of proteins by the cell.

Additional Information:
The interphase of the nucleus has elaborate
nucleoprotein fibres known as chromatin granule and nucleoli. looking on the position of the kinetochores round the centromere , chromosomes are of 4 types - 1. Metacentric – centromere is within the centre forming 2 equal arms.
Sub - metacentric – centromere the circular structure is slightly aloof from the centre resulting in formation of 1 short arm and one long arm.
Acrocentric -centromere is present toward the one arm , resulting in the formation of a really long arm and a very short arm.
Telocentric - body contains a terminal cytoplasm. it ends up in formation of 1 terribly short arm or negligible and one additional long arm.

Note: Nucleus and offers stain as associate degree organ was 1st represented by Robert Brown in 1831.
Fleming coined the term chromatin granule can also be outlined as condensed chromosomes for the fabric of the nucleus stained by basic dyes.
The nuclear matrix of the nucleus was termed because the karyoplasm contains the cell organ and chromatin( the condensed variety of chromosome).
