- 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...
- The Y Chromosome Has Several Male-specific Genes
KEY CONCEPTS:The Y chromosome has ~60 genes that are expressed specifically in testis. The male-specific genes are present in multiple copies in repeated chromosomal segments. Gene conversion between multiple copies allows the active genes to be maintained...
- 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...
- # 29 Dna Structure
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure....
- Sex Determination In Animals
Sex chromosomes and AutosomesMost of the diploid organisms are with separate sexes. The organisms producing sperms are called males and those producing eggs (ova) are called females. Chromosome is the major factor to determine the sex of an organism. The...
