With reference to the recent developments in science, which one of the following statements is not correct?

(a)

Functional chromosomes can be created by joining segments of DNA taken from cells of different species.

(b)

a) Functional chromosomes can be created by joining segments of DNA taken from cells of different species.

(c)

A piece of DNA taken out from an animal cell can be made to replicate outside a living cell in a laboratory.

(d)

Cells taken out from plants and animals can be made to undergo cell division in laboratory petri dishes.

Correct Answer

(a)

Explanation

Option(b)
Pieces of artificial functional DNA can be
created in laboratories. In 2007 Scientists in
Japan reported development of the world’s first
DNA molecule made almost entirely of artificial
parts. The finding opened up huge possibilities
in gene therapy.
Option(c)
A piece of DNA taken out from an animal cell can
be made to replicate outside a living cell in a
laboratory. It is exactly what is done through
Polymerase chain reaction (PCR) technology.
Option:(d)
Cells taken out from plants and animals can be
made to undergo cell division in laboratory petri
dishes
Option (a) Functional chromosomes can be
created by joining segments of DNA taken from
cells of different species is incorrect as it is
functional DNA which can be created through
recombinant DNA technology by joining DNA
taken from different species.
