Dna damage can occur as a result of exposure to chemicals or ultraviolet radiation. This is what happens during nucleotide excision repair of damaged dna. A multienzyme complex crosses the DNA in search of distortions in the double helix, once located, the phosphate skeleton of the affected chain is cut on both sides of the altered region, a helicase eliminates the oligonucleotide resulting from digestion, the "Gap" "is filled with a DNA polymerase and a ligase.

Answer:

Flexor Group- group of five muscles mainly in charge of movements of forearm, hand and fingers.

Peroneal Group- these muscles play a role in the movements of the ankle joint  and support of the foot.

Hamstring Group- The hamstrings are a group of muscles and their tendons at the rear of the upper leg. They include the biceps femoris, semitendinosus, and semimembranosus. The hamstrings flex the knee joint and extend the thigh to the back side of the body.

Gluteal Group- The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur.

Quadricep Group- The Latin translation of 'quadriceps' is 'four headed,' as the group contains four separate muscles: the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris. Each of the vastus muscles originates on the femur bone and attaches to the patella, or kneecap.

Extensor Group- The superficial extensors of the forearm are a group of six muscles situated in the superficial posterior compartment of the forearm. These muscles include the brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, extensor carpi ulnaris  and extensor digiti minimi.

Sartorius Group- couldnt  find anything

Adductor Group- The adductors are a group of muscles, as the name suggests, that primarily function to adduct the femur at the hip joint. Although they are all located somewhere along the medial side of the thigh, they originate in different places at the front of the pelvis.

I don't really understand just started high school
Ksenya-84 [330]
A forest fire would burn large trees, fertilizing the soil and makes room for smaller plants to grow, which provides more food for herbivores. The lack of trees also makes it easier for carnivores to hunt prey. Good luck in high school!
