Which of the following is not an antibiotic?

  1. Griseofulvin

  2. Cephalosporin

  3. Citric acid

  4. Streptomycin

  5. Both (A) and (C)
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Citric acid is a weak organic acid with the formula -CHO. It is a natural preservative or conservative which occurs naturally in citrus fruits and is also used to add an acidic or sour taste to foods and drinks. Griseofulvin is an orally administered antifungal drug. It is used both in animals and humans, to treat fungal infections of the skin and nails. Whereas cephalosporins are a group of broad spectrum, semi-synthetic beta-lactam antibiotics derived from the mould Cephalosporium. Streptomycin is an antibiotic (antimycobacterial) drug, the first of a class of drugs called as aminoglycosides to be discovered,

Modern biotechnology is based on

  1. Protoplast fusion

  2. Tissue culture

  3. Recombinant proteins

  4. Genetic engineering
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Modern biotechnology is based on the the methods of genetic engineering.  It is a technique which involves the introduction of foreign DNA carrying the desired gene of interest into the host organism & thus change the phenotype of the host organism.

So, the correct option is 'Genetic engineering'.
