Chromosome are the close meaning of all jail cellphone components. They are the carrier of genes as well as inwards that they command hereditary as well as variation. Chromosome were start observed past times Hofmeister (1849) inwards the pollen woman raise cells of Tradescantia. But, the term chromosome was introduced past times Waldeyer (1988). There exists a abrupt distinction betwixt prokaryotic as well as eukaryotic chromosome. Prokaryotic chromosome is real uncomplicated as well as composed of a unmarried deoxyribonucleic acid molecule. Eukaryotic chromosome is highly complex amongst unlike components, namely DNA, RNA, basic proteins as well as nonbasic proteins. at that topographic point are ii kinds of eukaryotic chromosomes, namely autosomes as well as gender activity chromosomes. Autosomes acquit the genes which command somatic or non sexual characters, as well as gender activity chromosomes comprise the genes which command sexual characteristics.
Prokaryotic chromosome vs Eukaryotic Chromosome
Prokaryotic chromosome
1. Primarily haploid
2. deoxyribonucleic acid is non complexed amongst proteins
3. The basic proteins histones are altogether absent.
4. Chromosomal deoxyribonucleic acid is localized inwards the cytoplasm.
5. Chromosomal deoxyribonucleic acid is a shut round down polymer
6. No definite morphological stage for deoxyribonucleic acid replication.
Eukaryotic Chromosome
1. Primarily diploid
2. deoxyribonucleic acid is complexed amongst proteins forming deoxyribonucleoprotein
3. Histones are chacteristically present.
4. Chromosomal deoxyribonucleic acid is confined inside the nucleus.
5. Chromosomal deoxyribonucleic acid is a linear polymer
6. deoxyribonucleic acid replication occurs inwards the southward stage of mitotically cycle.
