If one strand of DNA has the base sequence TTCCGGAA The complementary strand has which of the following sequence?
Mazyrski [523]

Answer:

If a DNA strand has the base sequence TTCCGGAA the complementary strand has the sequence AAGGCCTT.

Explanation:

A DNA molecule is constructed from sequences of its four nitrogenous bases: adenine, thymine, guanine and cytosine. Since DNA is made up of two strands, the sequence of nitrogenous bases of one strand is complementary to the other .

The complementarity of the bases is a characteristic of the nitrogenous bases in the nucleic acids to combine with their complementary base, which is the same as saying that purines complement with pyramidines.

  • <em>Adenine is combined with Thymine A=T </em>
  • <em>Cytosine is complemented with Guanina C≡G </em>

In this way, given a sequence on a DNA strand :

<em>     T-T-C-C-G-G-A-A</em>

The complementary strand will have this sequence:

<em>     A-A-G-G-C-C-T-T</em>
