You have a strand of DNA with the nucleotide sequence AGATCGATT. The complementary strand will have which of the following sequences?
A) CTGGATCGG
B) TCTAGCTAA
C) AGTTCGATT
D) GACCTAGCC

The answer is B

Explanation:

with complementary strands A goes with T

and G goes with C

   so         AGA TCG ATT

becomes TCT AGC TAA

you can see how you swap A's with T's and C's with G's. and vice versa.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
