DNA damage can occur as a result of exposure to chemicals or ultraviolet radiation. What happens during nucleotide excision repair of damaged DNA? A. Enzymes delete an incorrect DNA sequence, pull the gap closed, and join the bases on either side of the gap together B. Enzymes cut out the damaged gene, copy the same gene from the homologous chromosome, and insert the copy C. Enzymes detect an incorrect DNA base pairing in a DNA strand, remove the incorrect base, and insert the correct base. D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.

Answer:

D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.

Explanation:

From time to time, the DNA gets exposed to certain chemicals or radiation that damages it. However, the cell has a DNA repair mechanism in place called NUCLEOTIDE EXCISION REPAIR (NER).

NUCLEOTIDE EXCISION REPAIR (NER) is one of the DNA repair mechanisms in which certain enzymes open the DNA strand, remove a segment of DNA that contains the damaged gene or nucleotide bases, and resynthesize the correct DNA sequence using the pair of the damaged one.

Which statement describes an interaction between the biosphere and the atmosphere that is related to
photosynthesis?
During photosynthesis, plant roots take in water from soil.
During photosynthesis, plants take in carbon dioxide from the air.
Through photosynthesis, energy stored in plants is released into the air.
Through photosynthesis, energy stored in plants is transferred to humans who eat them.
