|
Answer» chromosome is a deoxyribonucleic acid (DNA) molecule with part or all of the genetic material (genome) of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle.[1][2] chromosome is a deoxyribonucleic acid (DNA) molecule with part or all of the genetic material (genome) of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle.[1][2]Chromosomes are normally visible under a light microscope only when the cell is undergoing the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form).[3] Before this happens, every chromosome is copied once (S phase), and the copy is joined to the original by a centromere, RESULTING either in an X-shaped structure (pictured to the right) if the centromere is located in the MIDDLE of the chromosome or a two-arm structure if the centromere is located near one of the ends. The original chromosome and the copy are now called sister chromatids. During metaphase the X-shape structure is called a metaphase chromosome. In this HIGHLY condensed form chromosomes are EASIEST to distinguish and study.[4] In animal cells, chromosomes reach their highest COMPACTION level in anaphase during chromosome segregation.[5] chromosome is a deoxyribonucleic acid (DNA) molecule with part or all of the genetic material (genome) of an organism.

Dawin theory of natural selection |
|
Answer» Answer:- Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of SMALL, inherited variations that increase the individual's ability to compete, survive, and REPRODUCE. The four key points of Darwin's Theory of Evolution are:- 1. Individuals of a species are not identical 2. TRAITS are passed from GENERATION to generation 3. More offspring are born than can survive 4. And only the survivors of the competition for resources will reproduce. |
