If a portion of a strand of DNA bases reads 5' AGCTAGCGT 3', what would the sequence of bases on the complementary strand read?

A.

3' TCGATCGCA 5'

B.

3' TCGUTCGCU 5'

C.

3' AGCTAGCGT 5'

D.

5' SucGAUCGCA 3'

Answer and Explanation

The Correct Answer is A

The sequence of bases on the complementary strand of DNA would read 5' TCGATCGCA 3'. In DNA, the nitrogenous bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The complementary strand is also antiparallel to the original strand, meaning that it runs in the opposite direction with the 5' end matching up with the 3' end of the original strand. The other options do not accurately represent the complementary sequence of bases or the antiparallel orientation of the strands.

Correct Answer is C

Explanation

The study does not indicate a causal relationship between the processes. A correlation between two processes means that there is a statistical relationship between them, but it does not necessarily imply causation. In other words, just because two processes are correlated does not mean that one causes the other.

A. The study does not indicate that Process A causes Process B.

B. The study can indicate whether Processes A and B have a positive relationship if the correlation is positive.

D. The study can indicate whether Processes A and B have a negative relationship if the correlation is negative.
