QUESTION 5 Write the complementary DNA strand for the following polynucleotide.
5' ATGGCAATCCTATAG 3'

5' CTATAGGATTGCCAT 3'

Explanation:

Writing the complementary strand for any set of DNA can easily be done by reading the strand and adding the opposite base pairs.

A ---> T (Uracil in RNA)

G ---> C

For Example, The complementary strand of

5' AGCTAGAT 3'  is 3' TCGATCTA 5'

you could then flip the whole thing to read 5' ATCTAGCT 3' if required to do so.

It would be "TACCGTTAGGATATC"

Explanation:

A (adenine) always pairs with T (thymine)

G (guanine) always pairs with C (cytosine)

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.

the answer is b.) hydrogen bonds between bases.
