Question

Directed modulation of microbial metabolic pathways using genetic methods is known as:

a) systems biology

b) metagenomics

c) metabolic engineering

d) biotechnology

e) systematics

Answer 1

Ans:

c) metabolic engineering

Explanation: Metabolic engineering is the modification of organism's metabolic pattern by using gentic methods like introducting trangenes (through genetic engineering) for the production of new, modified or more quantities of metabolites. This affects enzymatic, transport and regulatory function. One of such example is two gene involved in polyhydroxybutyrate (PHB; produce biodegradebale plastic) production are tranferred from Alcaligenes eutrophus to E.coli. The computational and mathematical analysis of biological orgenism is called system biology.. The study of genetical material recoverd from envrionment samples is called metagenomics. Systematics is the branch of biology deals with identification, nomenclature and classification of biological sample.
