A electrophoresis gel A restriction enzyme Polymerase chain reaction A plasmid Question 43 1 pts What is a genetically modified organism (GMO)? Any agricultural organism produced by breeding or biotechnology A hybrid organism A plant with certain genes removed An organism with an artificially altered genome

Answer 1

Question: what carries a gene from one bacterial cell to another bacterial cell?

Sol: Right option- A plasmid

Because plasmid is a autonomously replicating circular DNA and it is use as a vector for transferring the gene from one bacteria cell to another bacteria cell.

Another option is incorrect because:-

PCR is a polymerase chain reaction that is use to amplified the gene.

Restriction enzyme is a enzyme is known as molecular scissor, it is used to cutting the genome in a particular site.

Gel electrophoresis this a method for separation and analysis of macromolecules( DNA,RNA) and their fragments, based on their size and charge.

Question:- what is a generically modified otganisms( GMO)?

Sol: Right option- An organism with an artificially altered genome.

Other option excluded because:-

A genetically modified organism is a organism whose genetic materials has been altered using genetic engineering techniques. Example- Golden rice

Hybrid is not a GMO because hybrid are crossed manually in the field, but GMO are created using high technical method such as gene splicing, and sometimes Combining genes from different species to yield organisms that could not occur in nature

And removal of gene from a plant is a techniques in biotechnology.
