Selecione uma das seguintes:

  • -nucleotides are not arranged in the same order in all species
    -in all species, the amounts of adenine and thymine in the DNA are always similar, as are the amounts of guanine and cytosine.

Questão 18 de 25

3

What happens in the process of replication?

Selecione uma ou mais das seguintes:

  • 1. the strands of the double helix separate from each other, much like a zip unzipping, leaving the bases exposed
