DNA damage can occur as a result of exposure to chemicals or ultraviolet radiation. What happens during nucleotide excision repa
ir 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.
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.
RNA is a single-stranded nucleic acid. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine. There are many different types of DNA RNA is single stranded RNA forms a double helix.
<span>The minimal amount of nutrients needed every day by healthy people to prevent nutrient deficiencies is called the RDA. RDA stands for recommended dietary allowances. </span>RDA's are established by the Food and
Nutrition Board of the National Academy of Sciences. There is a term RDI related to this. RDI stands for recommended daily intake.
May not be right, but because of Oxygen and the growing of new skin? We rub our skin without noticing and it will become frail and rub off, creating new skin
Generally the low pitched sound vibrates the basilar membrane close to its apex while high pitched sound vibrates the basilar membrane close to its base
Brain receives information at temporal lobe. Thus, high and low pitched sounds are received at the higher and lower part of the temporal lobe.
