Which chromosome has lowest number of genes?

Chromosome Y
Chromosome Y contains the least number of genes.

Which human chromosome has maximum number of genes?

chromosome 1
The chromosome 1 is known to contain the maximum number of genes due to the large number of genes it carries.

Which chromosome of man has the least number of genes Class 12?

the Y
Answer: (c) In humans, chromosome 1 has highest genes (2968 approx.) and the Y has the fewest (231 prox.) genes.

How many genes are in the human chromosome?

Human chromosomes contain a total of 20,000 to 22,000 genes, the majority of which have two or more alleles.

Does each chromosome have the same number of genes?

Different chromosomes contain different genes. That is, each chromosome contains a specific chunk of the genome. For example, in humans the gene for alpha globin, a part of the hemoglobin protein that carries oxygen in red blood cells, is found on chromosome 16.

How many genes do we have?

In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20,000 and 25,000 genes.

How useful ESTs are?

ESTs have proven enormously useful in delineating the gene content of organisms and the expression patterns of genes in various cells and tissues. Several hundred thousand EST sequences would reveal most of the abundant messages for an organism and many of the rare messages as well.

What is tag in bioinformatics?

TAGs are optional fields on a SAM/BAM Alignment. A TAG is comprised of a two character TAG key, they type of the value, and the value: [A-Za-z][A-za-z]:[AifZH]:.* The types, A, i, f, Z, H are used to indicate the type of value stored in the tag.

What is the biggest chromosome?

Our genetic information is stored in 23 pairs of chromosomes that vary widely in size and shape. Chromosome 1 is the largest and is over three times bigger than chromosome 22. The 23rd pair of chromosomes are two special chromosomes, X and Y, that determine our sex.
