What does it mean when we say the DNA is two complimentary, and is composed of antiparallel chains of nucleotides?
DNA have four bases named as guanine,adenine,cytosine and
thiamine.It is complimentary because in DNA adenine base of strand
pairs with thymine base of other strand and similarly guanine base
of one strand always pairs with cytosine base of other strand.This
show that two DNA strand are complimentary.
By antiparallel chains of nucleotides in DNA we means that in two
strands of DNA, 5' end of one strand faces 3' end of other.
