Molecular Basis...

A distinct mechanism that usually involves a short segment of DNA with remarkable capacity to move from one location in a chromosome to another. What is this called as?

Gel electyrophoresis is used for

The two polynucleotide chain in DNA are:-

Assertion: DNA polymerase-I acts as proofreader.

Reason: DNA polymerase-I removes mismatched nucleotides.

Which one of the following triplet codes, is correctly matched with its specificity for an amino acid in protein synthesis or as 'start' or 'stop' codon : -

Twenty five micrograms ($$25 \mu g$$) of DNA amounting five micromole ($$5 \mu$$mole) was cut using a specific restriction enzyme into two pieces. Subsequently, when it was analyzed on an agarose gel it showed two bands of 200 bp and 800 bp. If the length of the original DNA was 1000 bp, Which of the following options best quantifies each band?

Genetic information in a DNA molecule is coded in the

In the double helix model of DNA as proposed by J. D. Watson and F.S.C. Crick, each base pair is how far from the next base pair:

Production of a human protein in bacteria by genetic engineering is possible because

Assertion: The tRNA molecules possess anticodons.

Reason: It needs the message in form of codon.
