Does it matter if resection occurs in the 5′ to 3′ direction or the 3′ to 5′ direction?
Vadim26 [7]

Answer:

D) Yes, it is important that the single-stranded DNA have 3′ ends, so resection must occur in the 5′ to 3′ direction.

Explanation:

During homologous recombination, the exonucleases remove nucleotides from the free 5' ends of the DNA at the double-stranded breaks to create a double-strand gap.

Removal of more nucleotides from the free 5' ends creates 3' single-strand extension which in turn invades the intact homolog and pairs with its complementary sequence of the DNA. The invaded free 3' end is then extended by DNA polymerase to give rise to Holiday junctions.  

If the resection occurs in the opposite direction and creates overhangs with free 5' ends, the free 3' ends would not be available to serve as a primer to facilitate the replication.

A scientist uses radioactive dating to determine the age of a fossil and discovers that a hominid species may have existed much
Sphinxa [80]

Based on the scientific method, for the scientist using radioactive dating to determine the age of a fossil, the best way to increase reliability is by doing repeated analyses of the fossil finding it to be the same age each time.

<h3>What is the best way to increase reliability of a discovery?</h3>

In science, the reliability of findings can be increased by taking repeated measurements.

In the case of the scientist using radioactive dating to determine the age of a fossil, the best way to increase reliability is by doing repeated analyses of the fossil finding it to be the same age each time.
