Answer:
Monohybrid cross:
Monohybrid cross may be defined as the cross done by taking single trait at a time. The ratio of the monohybrid cross by the pure parent breed result in the formation of 3:1 phenotype in the second generation.The genotype ratio is 1:2:1.
Test cross:
Test cross may be defined as the cross between the unknown genotype and the recessive parents. This cross is done to determine whether the genotype is heterozygous or the homozygous dominant trait. The ration of the cross may vary depending on the genotype of the organism.
This is what I got I hope it 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
