This question was inspired by Peter Cock 's tweet
Ahem. Anyone know what longest known chromosome is? Is it *wheat* chromosome 3B at 995 Mbp (almost 1Gbp, a billion)? http://t.co/rvIWX1NC— Peter Cock (@pjacock) September 25, 2011
Most softwares (C, java...) use a int32 (unsigned or not) to store the length of the chromosome. It isn't enough when the length of a chromosome is greater than INT_MAX or UINT_MAX
# define INT_MAX 2147483647 # define UINT_MAX 4294967295U
So my question is:
- Is there any resource where one can find the length of the chromosomes. Something like BioNumbers.
- What's the length of the longest chromosome ?
