What are chromosome 2 traits?
What are chromosome 2 traits?
Chromosome 2 is noteworthy for being the second largest human chromosome, trailing only chromosome 1 in size. It is also home to the gene with the longest known, protein-coding sequence – a 280,000 base pair gene that codes for a muscle protein, called titin, which is 33,000 amino acids long.
What is the major substance of chromosomes?
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
