What modifications are necessary to rewrite the following DNA strand GGCATTGCA as a RNA strand?

Answer 1

I always place the "strand" vertically.

G

G

C

A

T

T

G

C

A

Then i think.. what bonds with what? G with C A with T and when RNA A with U. So in order for the DNA strand and the RNA strand to bond.. they have to have the appropriate reflections.

G - C

G - C

C - G

A - U

T - A

T - A

G - C

C - G

A - U

Therefore you're modifications have been made and your RNA strand is this:

CCGUAACGU

Hope this helps :)

Answer 2

To rewrite the DNA strand GGCATTGCA as an RNA strand, you need to replace thymine (T) with uracil (U) since RNA does not contain thymine. The RNA strand would be GGCAUUGCA.
