The events listed below are all necessary for homologous recombination to occur properly:
vladimir2022 [97]

Answer:

D) D, B, C, E, A, F

Explanation:

Homologous recombination (HR) is a DNA repair pathway that consists of the exchange between two identical (or very similar) DNA regions. The steps of HR are: 1-Strand exchange, which refers to the pairing between broken DNA regions; 2-Strand invasion in order to provide a DNA crossover (Holliday junction); 3- Branch migration, capable of extending the heteroduplex regions far away from DNA crossover, 4-Resolution, where Holliday junction is resolved by cleavage of the junctions; 5- In the last step, a DNA ligase enables the joining of DNA strands.

Multiply 5730 years by 2 since two half-lives have gone by for carbon.

<u>Explanation</u>:

The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years  

The half-life of carbon-14 is 5730 years.  

In this manner, after  

1 half-life there is 50 % = 1/2 of the first amount left.  

2 half-lives there is 25 % = 1/4 of the first amount left.  

25% is two half-lives.  

Every 50% of life requires 5730 years.  

So two half-lives require 2 × 5730
