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
<u>Answer</u>: umami
The umami taste receptors are activated by glutamate, which is found in proteins. Umami is one of the five basic tastes that describe food flavor.
The scaly skin of a snake is homologous to skin of a lizard.
Homologous is a term used to describe a part of two different animals that come from a common ancestor. This makes the part will have a very similar structure.
Other similar terms would be analogous where the part of the animals will have similar functions but comes from a different ancestor, thus have a different structure.
An onion is made up of plant cells and your skin is made up of animal cells. The only organelles that plants have that animals don't are the cell wall and chloroplasts.
