Question

if one strand of dna molecule has the sequence of bases 5-attgca-3, the other complementary strand would have the sequence ...

o 5-taacgt-3
o 5-tgcaat-3
o 5-uaacgu-3
o 3-uaacgu-5
o 3-taacgt-5

Explanation:

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). The complementary strand runs in the opposite 3'-5' direction. Given the 5'-ATTGCA-3' strand, the complementary bases are 3'-TAACGT-5'.

Answer:

3'-TAACGT-5'
