Insulin is a hormone produced by some pancreatic cells. Scientists have isolated the DNA sequence that codes for human insulin p

roduction Which of the following best predicts the effect of inserting this gene into the DNA of a bacterial cell?
А) The recombinant bacterium will produce human insulin using its own transcription and translation machinery.
B) The recombinant bacterium will not transcribe the human insulin gene because this gene is not normally found in the bacterial genome.
C) The recombinant bacterium will transcribe the gene but will be unable to translate the mRNA.

Answer:

А) The recombinant bacterium will produce human insulin using its own transcription and translation machinery.

Explanation:

Recombinant DNA technologies refer to molecular biology techniques used to create chimeric DNA sequences by using genetic recombination techniques. The resultant recombinant DNA can further be used for the production of desired gene products (proteins) both in vitro and in living organisms. DNA recombinant techniques involve the insertion of desired DNA regions into an appropriate vector such as, for example, in a plasmid that is amplified in bacteria. For this purpose, the desired DNA fragment is inserted into a plasmid vector by digesting both the target DNA and plasmid insertion sites with an appropriate restriction enzyme. Subsequently, a DNA ligase is used to join both DNA fragments from their ends. Finally, the transformed bacterial (host) cells are selected to express the desired inserted gene.

If organisms are of the same species, _____.
Nitella [24]

Answer:

The correct answer will be options-

1. they share genetic similarities

2. they can interbreed

3. they fall under the same genus

Explanation:

The taxonomic studies help the organism to identify, nomenclature and classification of the organism.

The classification system helps organize the organisms into several groups based on the similarity of the morphological characters. The species is the lowest group of the system which contains the organism which is reproductively isolated from the other group of organism.

If two organism is found to be of the same species shows that they share the same gene pool, belongs to the same genus and they can interbreed.

Thus, the selected options are the correct answer.
