Detailed explanation-1: -DMD, the largest known human gene, provides instructions for making a protein called dystrophin. This protein is located primarily in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle.
Detailed explanation-2: -Complete answer: The human dystrophin gene, with 79 exons spanning at least 2, 300 kilobases, is the biggest known gene (kb).
Detailed explanation-3: -So, the correct answer is ‘Dystrophin’ Was this answer helpful?
Detailed explanation-4: -The average gene consists of 3000 bases, but size varies greatly, with the largest known human gene being dystrophin as 2.4 million bases and TDF gene as the smallest gene with 14 bases. The total number of genes was estimated at about 30, 000, which is much lower than previous estimates of 80, 000 to 1, 40, 000 genes.
