If one DNA strand is 5'-GGCATTACACTAGGCCT-3', what is the complementary srand?

3' - CCGTAATGTGATCCGGA - 5'

Explanation:

In DNA, the leading strand builds from a 5' to 3' direction and the lagging strand (complementary strand) must build from a 3' to 5' direction.

The base-pairing rules for DNA are:

- adenine always pairs to thymine (A to T) (T to A)

- guanine always pairs to cytosine (G to C) (C to G)

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
