Answer:
The correct answer will be option-B (Semi-synthetic)
Explanation:
Chemical drugs can be synthesized through many ways on the basis of which they can be categorized:
1. Natural Drug: The drug prepared from the natural extracts.
2. Synthetic Drug: The drug is synthesized by chemical reactions.
3. <u>Semi-synthetic Drug</u>: The drug which is neither completely natural nor synthetic that is they are prepared from the natural extracts by modifying them.
Since in the given question, the drug was prepared by the converting side chain to the hydroxyl group of the antimicrobial drug therefore it is considered as the semi-synthetic drug and Option-B is the correct answer.
Answer:
This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.
Explanation:
Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).
Answer:
I'm pretty sure it B, hope I helped
