Why can a plant express a bacterial gene that has been added to its genome?
A plant can express a bacterial gene that has been added to its genome because plants have the ability to take up and incorporate foreign DNA into their own genetic material through a process called genetic engineering. This allows the plant to produce the protein encoded by the bacterial gene, which can confer new traits or characteristics to the plant.
Is a rice plant carrying a carrot gene a transgenic organism?
Yes, a rice plant that has been genetically modified to carry a carrot gene would be considered a transgenic organism. This is because it contains genetic material from a different species (carrot) that has been artificially inserted into its genome.
In the process of human gene cloning using recombinant plasmids what is the bacterial plasmid?
The bacterial plasmid is a small circular DNA molecule that is used as a vector to carry the gene of interest in gene cloning experiments. It is introduced into bacteria, where it replicates independently from the bacterial chromosome. The gene of interest is inserted into the plasmid using restriction enzymes and ligase.
How recombinant DNA has mass produced insulin?
By rDNA technology, the gene of interest can be transformed in to a lab organism,say bacteria; and by expressing that gene, large production of insulin or any other factor is possible. This can be tested for its activity after purification of the protein from the crude bacterial lysate.
Which of these is a gene that does not express itself and is concealed by the presence of another gene of the same trait?
A recessive gene is a gene that does not express itself in the presence of a dominant gene of the same trait. When an individual inherits two recessive genes for a trait, the recessive gene will be expressed.

What does the bacterial cell reproduce that the human gene codes for?
the bacterial cell reproduces the bacterial chromosome that the human gene codes for.
In a case of simple dominance what is the height of a plant with the genotype Tt?
The plants will all express the dominant gene.
How can large quantities of protein be produced from a bacterial colony containing the gene of interest?
Large quantities of protein can be produced by expressing the gene of interest in a bacterial colony such as E. coli. This is typically achieved by cloning the gene into a plasmid, transforming the plasmid into the bacterial cells, and inducing protein expression. The bacterial colony can then be grown in a culture medium optimized for protein production to maximize yields.
Is heat shock a method of gene transfer in bacterial cells?
Bacterial cell wall is made of peptidoglycan(a polymer consisting of both sugars and amino acids). So, when the bacterial cells along with the recombinant DNA is subjected to high temperature and suddenly brought down to low temperature(almost immediately - after 2mins), the protein structure gets denatured. By this, there form pores large enough for the recombinant DNA to enter the cell and express the desired gene when required.
A tobacco plant can be made to express a gene from fireflies resulting in the emission of light what is the basis for this phenomenon?
This phenomenon is based on genetic engineering techniques where the gene for bioluminescence from fireflies is inserted into the tobacco plant's genome. The gene encodes for an enzyme called luciferase, which catalyzes a reaction that produces light. When the gene is expressed in the tobacco plant, it leads to the production of luciferase and the emission of light, making the plant glow.

What is bacterial cloning?
Bacterial cloning is a process that involves the replication of a specific DNA fragment or gene of interest within a bacterial host cell. This is typically achieved by inserting the DNA fragment into a bacterial plasmid vector, which is then introduced into the bacterial cell for replication. Bacterial cloning is commonly used in molecular biology research to produce multiple copies of a particular gene or DNA sequence for further study.
