If one strand of DNA double helix has the following nucleotide sequence ATCGGTCAAGCTAGG what would the dna complementary stand r
joja [24]

Answer:

TAGCCAGTTCGATCC

Explanation:

In DNA, there are 4 different nucleotide bases. Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).

A (adenine) always pairs with T(thymine) and C(cytosine) always pairs with G (guanine).

If we have the strand:

ATCGGTCAAGCTAGG  

We have to pair A with T, and C with G. Therefore, the complementary strand of DNA will be:

TAGCCAGTTCGATCC
