Answer:

True.

Explanation:

The DNa molecule is made up of two antiparallel strands and complementary to each other. That's because each strand is polynucleotide, which means it is made up of several nucleotides.

Each nucleotide is formed by a nitrogenous base, a phosphate group and a sugar. The heterogenated bases of DNA are: adenine, guanine, thymine and cytosine, and they are responsible for linking the two strands of DNA, since the adenine of one strand is able to make connections with the thymine of the other strand and guanine from one strand is capable of making connections with the cytosine of another strand.

What is true about microevolution?
iris [78.8K]
Microevolution refers to changes that occur within a single species or group or organisms.  Microevolution, as opposed to macroevolution, occurs in a short period of time. In microevolution, the ancestor and the descendant obviously belong to the same type.  For example, certain pests have evolved in such a way that they become immune to pesticides; the same thing has happened to certain weeds and herbicides. Hope this helps.
