How many pairs of SAT chromosomes are present in human diploid cell?
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.
How many sat chromosomes are present in human gamete?
In human beings, the total number is 46 or 23 pairs named as ‘diploid’ (2n). While in gametes (male or female) the number is 23 i.e. ‘haploid’ (n).
What is meant by SAT chromosome?

How many chromosomes are present in a human diploid cell and in each gamete Class 10?
An example of a cell in a diploid state is a somatic cell. In humans, the somatic cells typically contain 46 chromosomes in contrast to human haploid gametes (egg and sperm cells) that have only 23 chromosomes.
How many chromosomes are present in human haploid cell?
In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
What are the 23 human chromosomes?
Humans have 23 pairs of chromosomes–22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y. Each parent contributes one chromosome to each pair so that offspring get half of their chromosomes from their mother and half from their father.
What happens when you have 47 chromosomes?
Humans have 23 pairs of chromosomes. A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.

About the SAT
This wasn’t always the case: when College Board introduced the SAT in 1926, the exam was called the Scholastic Aptitude Test. Since then, it has been through changes both in name and content. In 1990, it was renamed the Scholastic Assessment Test.

The chromosomes may have additional constriction or secondary constriction at their endsas distal part of the arm formed by chromatin thread are known satellite chromosome. These constriction gives appearance of an outgrowth or small fragment. These are also known as (sat) chromosomes or marker chromosome number.
Which of the following amino acid is present in basic protein of chromosome?
