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

Option A is incorrect because creating a functional chromosome by joining DNA segments from different species is exceptionally challenging. While creating artificial chromosomes is possible, making them functional is a different matter.

Option B is correct and refers to Artificial Gene Synthesis (also known as DNA printing), a synthetic biology method used to create artificial genes in the lab. This method has successfully generated functional bacterial or yeast chromosomes with approximately one million base pairs.

Option C is correct and alludes to Cloning, where DNA can be replicated outside a living cell.

Option D is correct and relates to Plant and Animal Tissue Culture Technology, where cells from plants and animals can undergo cell division in laboratory petri dishes.

Therefore, option A is the incorrect statement.
