Question

how does necleotide sequence in one chain of DNA compare with the other chain of DNA?

Answer 1

It is complementary. So, if for instance you have one strand of DNA with the nucleotide sequence: CGA TCA AGG, then its complement would be: GCT AGT TCC

Answer 2

Well, if you refer to make a DNA sequence comparation, you must have to use bioinformatic resources like the BLAST program. This program compare every nucleotid of each DNA sequence to the other and can tell you how and where they differ.

Hope this help you.

Answer 3

whatever nitrogenous base is found on one strand, their complementary bases would be found on the other strand according to the chargaff rule

i hope this answers your question :D
