Answer:
Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.
Explanation:
Trypsin and chymotrypsin are known as proteolytic enzymes which are actively involved in the digestive system. They are both secreted by the pancreas and are majorly involved in the breakdown of protein in the small intestine.
Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.
Answer:
B) Natural selection favored rabbits that were resistant to the virus
Explanation:
Most likely, virus resistance occurred over time, as a consequence of mutation. Individuals that carried the resistance mutation become favourable by natural selection.
Natural selection is evolutionary mechanism which favours traits of an organism that help him survive and reproduce (increase organism's fitness). In the example above, resistant rabbits that survived had the favorable trait (resistance) by natural selection.
B. chloroplast carrries out photo synthesis
Answer:
5’ – TAC-GCA-CTG-3’
Explanation:
As per the Chargaff’s complementary base pairing rule purine always pairs with a pyrimidine.
Purines include adenine (A) and cytosine (C)
Pyrimidine include thymine (T) and guanine (G)
Thus an A always pair with T and C always pair with G
Thus, the resulting poly peptide for the given amino acid sequence is
3'-ATG-CGT-GAC-5'
5’ – TAC-GCA-CTG-3’
