What is the molecular weight of a gene (two strands of DNA) if a protein with a molecular weight of 2400 is programmed in one chain?
October 31, 2020
1.2400: 100 (molecular weight of one amino acid) = 24 amino acids in a protein
2.24 x 3 = 72 nucleotides in one DNA strand
3.72 x 345 = 24840 – molecular weight of one gene chain, then two gene chains 24840 x 2 = 49680
Answer: 49680 amu
