Question 1-1 : How many megabases (M bp) long is chromosome 1? Answer 1-1: The human chromosome 1 is 250 Mbp.
What is the length of chromosome 1?
Chromosome 1 is the designation for the largest human chromosome. Humans have two copies of chromosome 1, as they do with all of the autosomes, which are the non-sex chromosomes.
|Length (bp)||248,956,422 bp (GRCh38)|
|No. of genes||1,961 (CCDS)|
|Centromere position||Metacentric (123.4 Mbp)|
How many BP are in a chromosome?
Chromosome 1 is the largest human chromosome, spanning about 249 million DNA building blocks (base pairs) and representing approximately 8 percent of the total DNA in cells. Identifying genes on each chromosome is an active area of genetic research.
How many bp long is a gene?
Human genes are commonly around 27,000 base pairs long, and some are up to 2 million base pairs.
What chromosome is eye color on?
Although there are about 16 different genes responsible for eye color, it is mostly attributed to two adjacent genes on chromosome 15, hect domain and RCC1-like domain-containing protein 2 (HERC2) and ocular albinism (that is, oculocutaneous albinism II (OCA2)).
What does the 12 chromosome do?
Chromosome 12 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 12 spans about 133 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells.
What is the shortest chromosome?
Chromosome 21 is the smallest human chromosome, spanning about 48 million base pairs (the building blocks of DNA) and representing 1.5 to 2 percent of the total DNA in cells.
What is the difference between protein and DNA?
DNA contains the genetic information of all living organisms. Proteins are large molecules made up by 20 small molecules called amino acids. … So in a living being nucleic acids contain the information that is passed to the proteins that are in charge of many functions, including rebuilding these nucleic acids.
