Answer:
Repair mechanism for base cleavage (BER)
Explanation:
Repair by base cleavage (BER)
The altered bases are specifically recognized by glycosylases and removed, generating an AP site. The hole is filled by a DNA polymerase that takes the healthy strand as a template. This system arises not only by exposure to external agents, but also by the cell's own activity.
In case of damage in more than one nucleotide, repair by nucleotide excision (NER) is performed.
Nucleotide excision repair (NER)
The damaged area is recognized by UvrA and B, then A and B separate and UvrC enters which forms a complex with endonuclease activity with B. This enzyme cuts the T-dimer and the gap is filled by a DNA polymerase. There is also the TC-NER system (transcription-coupled nucleotide repair system). The alteration of these mechanisms gives rise to diseases such as: Xeroderma pigmentosum, Trichotiodystrophy or Cockayne Syndrome

Answer:The lengthy small intestine receives secretions from the ______pancrease______ and ______liver______, completes digestion of the nutrients in _________chyme_______, absorbs the products of digestion, and transports the remaining residues to the ________large________ intestine.
Explanation: digestion of food is necessary for absorption of nutrients. In this process food is broken down into forms that can be absorbed by the body . food is broken down by the teeth and the enzymes in saliva,when it is in the mouth. From there it moves to the stomach through the oesophagus. In the stomach, the content is further mixed with enzymes and the churning breaks down food further.From the stomach food moves to the small intestine. In the small intestine, digestive enzymes from the pancreas and liver acts on food. The small intestine is where digested food is absorbed.it has a large surface area and finger-like projection called villi to carry out the function of absorbing nutrients.
From there, undigested food us passed to the large intestine from where it is passed out through the anus
