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

Defines genetically modified organisms as ones whose hereditary material (DNA) is altered in a manner that does not occur by normal mating, and says foreign genes are artificially inserted into a plant's genes.

A student could combine this with basic knowledge that inserting genes requires creating or handling DNA sequences in the lab, suggesting laboratory creation/manipulation of functional DNA segments.

States that cells use chemical reactions to build copies of their DNA, framing DNA as a molecule assembled by chemistry.

Knowing DNA is a chemical polymer, a student could infer that chemical or biochemical synthesis methods might be used in labs to assemble DNA pieces.

Notes that DNA copying is a biochemical process prone to small inaccuracies that create variations.

A student might extend this to the idea that deliberate changes (rather than accidental ones) can be introduced using laboratory techniques to create variant DNA sequences with functional effects.

Describes efforts to build a DNA barcode reference library and facilities for sequencing and preserving DNA extracts.

Given widespread sequencing and preservation infrastructure, a student could reason labs have the data and tools needed to design and then synthesize tested DNA sequences.

States that DNA copying is a basic event in reproduction and that cells use chemical reactions to build copies of their DNA.

A student can take the rule that DNA replication depends on chemical reactions and ask whether those reactions (enzymes, substrates, conditions) can be reproduced in a lab environment outside a whole living cell.

Explicitly notes that DNA copying is accompanied by creation/maintenance of an organised cellular apparatus and that simply having a DNA copy outside would lack that apparatus.

One could use this to reason that replication outside cells would require substituting or reconstructing the necessary cellular apparatus or its functions in vitro to enable copying.

Emphasises that DNA copying mechanisms operate inside cells and that copying is not perfectly accurate (errors arise from biochemical reactions).

A student could use this to consider whether isolated DNA in lab conditions would need the same biochemical machinery and whether fidelity of copying might differ outside cellular contexts.

Summarises that reproduction involves creation of a DNA copy and additional cellular apparatus by the cell involved in the process.

This summary supports asking if laboratory methods must provide both the copying chemistry and some form of supporting apparatus (enzymatic systems, controlled environment) to replicate DNA outside cells.

Describes regeneration where specialised cells proliferate and generate many cells—showing that DNA copying is tied to cellular proliferation performed by specialised cell machinery.

A student could infer that DNA replication in vitro would need to mimic specialised cellular proliferation machinery or provide the key components those cells use.

Describes tissue culture where cells removed from a plant are placed in an artificial medium and 'divide rapidly to form a small group of cells or callus.'

A student could infer that providing artificial medium and hormones can induce plant cells removed from a plant to divide in laboratory conditions (in vitro) and test this by attempting plant tissue culture in a sterile medium with growth regulators.

Explains regeneration: specialised cells proliferate and make large numbers of cells, which then differentiate into tissues.

One could extend this pattern to hypothesise that certain differentiated animal cells (or specialised regenerative cells) can be stimulated to proliferate outside the organism if given appropriate signals or environment and then design cell culture experiments to test proliferation.

Notes that unicellular organisms undergo cell division (fission) naturally, showing that cells inherently possess division mechanisms.

Combine this basic rule with the idea that if single cells divide naturally, providing suitable lab conditions (nutrients, sterile environment) might allow isolated cells to divide in vitro, so one could attempt to culture isolated single cells to observe division.

Describes cell division processes (meiosis) in germ cells as a defined cellular mechanism for producing new cells.

A student can infer that since cell division is a definable cellular program (mitosis/meiosis), it may be triggered or supported in isolated cells under controlled lab conditions (e.g., by supplying energy/nutrients or appropriate cues) and plan experiments to culture germ or somatic cells to observe division.

Shows that plant cells (onion peel) are readily observable under microscope and exist as intact units, implying they can be isolated and studied.

A learner might extend this by isolating visible plant cells and attempting to culture them on media to see whether they undergo division in vitro.
