If one strand of a DNA has the sequence ATGCTTCA, sequence of the bases in complementary strand is:

Question

Canvas Classes · Accepted Answer

DNA consists of two anti-parallel complementary strands where:
- Adenine (A) pairs with Thymine (T)
- Guanine (G) pairs with Cytosine (C)

Given the sequence of one strand (conventionally written from 5' to 3'):
5' - A T G C T T C A - 3'

The complementary bases would be:
3' - T A C G A A G T - 5'

Reading the complementary sequence appropriately matched to the options gives TACGAAGT.
