What are chromosomes and how do they differ in Prokaryotic and Eukaryotic chromosomes?
- Prokaryotes Vs Eukaryotes
While eukaryotic cells and prokaryotic cells have some characteristics in common, they diverged from their common ancestor billions of years ago, thus accounting for significant differences in overall structure and function. Here we will go over them....
- Chromosomal Aberration
Chromosomal aberration refers to a change in number of chromosomes, can occur on one, or several, or all of the chromosomes within a nucleus. This is cause by the failure of sister chromatids to separate during anaphase of mitosis or the failure of homologous...
- Autosomes & Sex Chromosomes
All About Autosomes and Sex Chromosomes: Let me start off by explaining that Autosomes and Sex Chromosomes are from the same chromosome, which contains 46 chromosomes total. In each chromosome there are TWO Sex Chromosomes out of the total 46...
- What Is The Cause Of Turner's Syndrome?
A) Presence of additional copy of X-chromosome. B) Absence of one of the X-chromosomes C) Trisomy of chromosome number 21.D) None of these The correct answer is: B) Absence of one of the X-chromosomes...
- Diploid Chromosome Number
Humans have a diploid chromosome number of 46 chromosomes. In other words, there are a total of 46 chromosomes in human cells. The diploid number varies depending on each species. Having a diploid chromosome number means that an organism?s cells contain...
