4. No
5. Whatever amount of Guanine there is, there has to be an equal amount of cytosine. So, if there are 5 guanine bases, that means
that there has to be 5 cytosine bases as well.
6. 10
bases will be found, cause Every thymine must connect with an adenine nitrogen base by two hydrogen bonds.
7. Because every arrangement of the bases in the
DNA strand result in a different protein, thus making different genes, and
there is an infinite number of arrangements nitrogen bases can exists in the
DNA.
