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.

Answer:

(a)

Moderate

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.
