Question: What is the maximum length of chromosome?


What is the length of one chromosome?

Chromosome 1 spans about 249 million nucleotide base pairs, which are the basic units of information for DNA. It represents about 8% of the total DNA in human cells.

Chromosome 1
Length (bp) 248,956,422 bp (GRCh38)
No. of genes 1,961 (CCDS)
Type Autosome
Centromere position Metacentric (123.4 Mbp)

How big is a chromosome in CM?

I guess if you assume the DNA is at rest with an average rise of 3.4 A per base pair, then the length of chr1 would be 3.4A * 249*10^6, i.e. 847*10^6A, i.e. ~85 mm, or 8.5 cm.

How many centimeters are in a chromosome?

Every person has approximately 6800 centimorgans of DNA. This number includes both copies of each numbered chromosome, or approximately 3400 centimorgans inherited from each parent. Some sources estimate the number of centimorgans that has a person has at 7200 cMs, or even a very specific number like 7074.60.

How is DNA length calculated?

The total length of the DNA can be easily obtained by applying a simple equation. The total length of DNA (double helix) = total numbers of base pairs × distance between two consecutive base pairs.

How long is the largest human chromosome?

Two copies of chromosome 1, one copy inherited from each parent, form one of the pairs. 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.
