Dna damage repair by non-homologous end joining (nhej)
a. occurs during gene conversion.
b. is responsible for the repair of o6meg adducts.
c. is absent in xeroderma pigmentosum (xp)
d. result in the loss of genetic information.
e. repair spontaneous dna depurination.

D.  result in the loss of genetic information.

Explanation:

Ligation of broken DNA ends during non-homologous end joining (NHEJ) causes loss of genetic information.

Cellular nucleases are the enzymes that degrade the nucleotides at the breakage site. The loss of nucleotides results in the loss of part of or whole gene/s.

The process of NHEJ does not need a template and hence, can occur at any stage of the cell cycle. Here, imprecise joining and cellular nucleases during non-homologous end joining (NHEJ) result in the loss of nucleotides.

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
