Answer:
The correct answer is D.
Explanation:
The Ras Proto-Oncogene is a gene found in normal cells, which by the single point mutation mentioned in the question, can turn into Oncogene. Because Proto-Oncogene is a gene that controls and regulates the division of the cell, a mutation in this gene leads to uncontrolled cell divisions which then leads to cancer. The correct answer is D since RAF-Activation describes "Rapidly Accelerated Fibrosarcoma, fibrosarcoma being a cancer which affects fibrobalst cells.
I hope this answer helps.
Answer:
Explanation:
1. charge in trypsin
: two other molecules in elastase
2. Chymotrypsin cleaves peptide bonds after bulky or aromatic side chains, such as those of the amino acids phenylalanine or tyrosine. The specificity pocket, or substrate-binding site, is deep and has hydrophobic side chains.
Trypsin cleaves peptide bonds following basic amino acid side chains. Lysine and arginine both have basic amino acid side chains that are positively charged at pH 7. Trypsin's substrate-binding site contains a negatively charged amino acid residue.
Elastase cleaves peptide bonds after amino acids with small side chains, such as glycine, alanine, or valine. The specificity pocket for elastase has bulky side chains that block larger amino acid side chains, but can accomodate smaller side chains, such as the -H, -CH3, and -CH(CH3)2 side chains of glycine, alanine, and valine, respectively.
3. Their binding pockets
- trypsin = long & (-) D on bottom
- chymotrypsin = deep & wide
- elastase = aliphatic a.a. = shallow
Answer:
Fairy penguins (Eudyptula minor), also known as little penguins, are tiny, slate-blue animals found along the coastlines of southern Australia and New Zealand. Not only are they more colorful than most aquatic birds, but they're also notably smaller, growing to be less than a foot tall and about 2.5 pounds.
