Question

If one side of DNA reads AACTTCA what would the complimentary side read?

Answer 1

I get `"TTGAAGT"`.

Explanation:

A DNA base includes `4` types of nitrogenous bases, adenine, guanine, thymine, and cytosine. In there, there are `2` purine bases (adenine and guanine), and `2` pyrimidine bases (thymine and cytosine).

Each purine base pairs with a pyrimidine base via hydrogen bonding. Adenine will bond with thymine, while guanine bonds with cytosine. In RNA however, thymine is substituted with uracil.

If we are still talking about DNA, as in this case, then we can figure it out by just changing base pairs.

We got:

`"AACTTCA"`

Remember:

`"A"` turns to `"T"` (and vice-versa)

`"C"` turns to `"G"` (and vice-versa)

So, the complement of this side would be:

`"TTGAAGT"`
