Molecular Genetics

DNA carries the genetic code for the synthesis of specific proteins.

• True
• False

DNA becomes highly condensed structures known as chromatin threads.

• True
• False

There is 24% adenine, 18% cytosine and 18% guanine in a DNA strand. How many percentage of thymine is there in the same DNA strand?

• 24%
• 40%

The basic unit of DNA is a polypeptide.

• True
• False

A nucleotide is made up of sugar-phosphate backbone and a nitrogenous base.

• True
• False

Genetic engineering is possible as the genetic code in living organisms is universal. 

• True
• False

A restriction enzyme acts as a "scissors" to cut the gene of interest from the chromosome.

• True
• False

DNA ligase anneals the plasmid and the gene of interest to form a recombinant plasmid.

• True
• False

The recombinant plasmid is heated temporarily to enter the bacterium to form a transgenic bacterium.

• True
• False
