Question

Eukaryotic vs prokaryotic chromosomes, consider the following: histones, arrangement, and number of chromosomes

Answer 1

Eukaryotic vs prokaryotic chromosomes, consider the following: histones, arrangement, and number of chromosomes.

Ans.The distinction between prokaryotic and eukaryotic is considered to be the most important distinction amonge groups of organisms.eukaryotic cells contain membrane-bound organelles,such as the nucleus,while prokaryotic cells do not.Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts,the cell wall ,and the structure of chromosomal DNA.

Prokaryotes were the only form of life on earth for millions of years until more complication eukaryotic cells came into being thought the process of evolution.
