DNA calculations !!! Watch
2^5 = 32
2^6 = 64, so you want 6 bases per codon.
ONe complete turn of the double helix of DNA contains 10 pairs of bases and is 3.4 nm long. What is the approximate length of the DNA coding sequence of lysozome, a protein of 129 amino acids ?
A. 132 nm
B. 113 nm
i dont understand that how 38.7 turns are required ??
As you are told that one turn of the helix is 10 bases, that means 387 bases will be 387/10 turns = 38.7 turns.
