The two strands in a dna helix are described as being antiparallel, or in opposite orientations. if one dna strand is in the 5' to 3' orientation, the complementary dna strand is orientated in which direction?

The answer is 3' - 5' direction

Explanation:

Since the template strand runs in 5' - 3' direction, antiparallel nature of the DNA double helix explains that the complimentary strand (non-template strand) runs in a 3' - 5' direction

3' to 5'

Explanation:DNA consist of two strands that runs anti-parallel. the first called the leading strand and its runs from 5' to 3' orientation meaning it runs from carbon 5 to carbon 3 while the second strand is called the lagging strand or the ozazaki fragment it runs from 3' to 5' i.e from carbon 3 to carbon 5.

The two strands cannot be replicated in a row hence the need for the break into the leading that replicates towards the replication fork and lagging strand replicates towards the opposite direction.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
