A change in the number or structure of chromosomes is called
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome.
each side of the chromosome is called a chromatid they are bonded together by the centromere
A spooled string of genes packaged in a single unit is called a chromosome. A chromosome is a structure of DNA, RNA, and protein which are found in cells.
A sat chromosome, short for satellite chromosome, is a chromosome with a secondary constriction that contains highly repetitive DNA sequences called satellite DNA. These regions appear as small, secondary appendages on the chromosome and play a role in chromosome structure and organization.
Chromatin is tightly coiled and wrapped around proteins called histones to form structures called chromosomes
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome.
At the beginning of cell division, DNA and the proteins associated with the DNA coil into a structure called a chromosome. Chromosomes are visible under a microscope and contain the genetic material (DNA) of an organism.
DNA is packaged into a chromosome by wrapping around proteins called histones, forming a structure known as chromatin. This chromatin then coils and condenses to create the compact structure of a chromosome.
The rod-shaped structure of tightly coiled DNA found in the cell nucleus of plants and animals is called a chromosome.

A chromosome is an organized structure of DNA and protein that is found in cells.In biology, mutations are changes to the nucleotide sequence of the genetic material of an organism.

The three chromosomal aberrations - deletion, duplication, and inversion - are different in terms of the changes they cause in the chromosome structure. Deletion involves the loss of a segment of the chromosome, duplication results in the presence of extra copies of a segment, and inversion entails the reversal of a segment within the chromosome. These aberrations are similar in that they can all lead to genetic disorders or abnormalities due to the changes in the chromosome structure they cause.

This is known as polyploidy, where cells have extra sets of chromosomes. Polyploidy can occur naturally or be induced experimentally, and it can lead to changes in an organism's characteristics and traits. This phenomenon is commonly observed in plants.

The region is called the centromere.
