Question

plz help!!! If this is a sequence of one DNA strand, what is the complementary sequence of the other DNA strand? DNA: A T T C A G C G A

Answer 1

T A A G T C G C T

Step-by-step explanation:

DNA strand: A T T C A G C G A

complementary DNA strand: T A A G T C G C T

This is a very important rule:

Four kinds of nitrogenous bases in DNA: Adnine (A), Thymine (T), Guanine (G), Cytosine (C)

And this is how they're coupled:

A = T

C = G

For example::

First DNA strand: A T G C

complementary strand: T A C G
