Functional chromosomes can be created by joining segments of DNA taken from cells of different species.
Correct AnswerPieces of artificial functional DNA can be created in Iaboratories.
Incorrect AnswerA piece of DNA taken out from an animal cell can be made to replicate outside a living cell in a laboratory.
Incorrect AnswerCells taken out from plants and animals can be made to undergo cell division in laboratory petri dishes.
Incorrect AnswerExplanation:
Option A incorrect since it is difficult to envisage how this can be achieved because it is one thing to create an artificial chromosome and quite another to to make it functional. Option B is Artificial Gene Synthesis whereas Option D is Plant and Animal Tissue Culture Technology. Option C is Cloning.
Artificial gene synthesis, sometimes known as DNA printing is a method in synthetic biology that is used to create artificial genes in the laboratory. The method has been used to generate functional bacterial or yeast chromosomes containing approximately one million base pairs.
