The answer is A: reactants
Peptidoglycan is present in the cell wall of gram-positive bacteria. Bacteria are safeguarded by a robust cell wall comprising peptidoglycan. The layer of peptidoglycan in the cell wall of bacteria refers to a crystal lattice composition produced from linear chains of two alternating amino sugars, that is NAM (N-acetylmuramic acid) and NAG (N-acetylglucosamine). Peptidoglycans is one of the most essential sources of D-amino acids in nature.
Europeanizationefers to a number of related phenomena and patterns of change: The process in which a notionally non-European subject (be it a culture, a language, a city or a nation) adopts a number of European features (Westernization).
Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
