Plasmids are autonomouslyreplicating minichromosomes found in......
Plasmids are small, circular pieces of DNA that replicate independently of the chromosomal DNA. They are commonly found in Escherichia coli (E. coli) bacteria, making this the correct answer.
Improvement of genotype of an organism by addition of some foreign gene is
Genetic engineering aims to add new DNA to an organism to add one or more new favorable traits which are not found in that organism.
Two bacteria found to be veryuseful in genetic engineering experiments are
Escherichia coli (E. coli) and Agrobacterium tumefaciens are two bacteria commonly used in genetic engineering. E. coli is widely used as a model organism and for the production of recombinant proteins, while Agrobacterium is used to transfer genes into plants.
The organism whoes gene have been artificially altered for desired efect is called as
A genetically modified organism (GMO) is an organism whose genetic material has been artificially altered using genetic engineering techniques. This is done to introduce new traits or characteristics, such as resistance to pests or improved nutritional content.
The sequence of DNA that reads the same backward and forward across the double strand is
A palindromic sequence in DNA is a sequence of base pairs that reads the same forward and backward on the two strands of the double helix. For example, the sequence 5'-GAATTC-3' on one strand reads 3'-CTTAAG-5' on the complementary strand.
Ti Plasmid is a cloning vector which works with
The Ti plasmid (Tumor-inducing plasmid) is a type of plasmid from the bacterium Agrobacterium tumefaciens. It is commonly used as a cloning vector for introducing genes into dicot plants. Dicots are a group of flowering plants whose seeds typically have two embryonic leaves or cotyledons.
During which of the following techniques host cells are exposed to pulse of high voltage current ?
Electroporation is a technique in which host cells are exposed to a pulse of high voltage current. This creates temporary pores in the cell membrane, allowing foreign DNA to enter the cell.
Which of the following is related withgenetic engineering ?
Transgenic organisms are those that have been genetically modified to contain and express foreign genes. Genetic engineering involves the direct manipulation of an organism's genes, often through the introduction of transgenic elements.
Which of the bollowing statement is incorrect ?
A cosmid is a type of hybrid plasmid that contains a cos site from the lambda phage. It does not contain genes coding for viral proteins, but it can replicate like plasmids, have antibiotic resistance markers, and has cos sites that help form circular DNA.
Assertoin- Reason type Questions A is assertion R is reasoning A - The term hybridoma is applied to fused cells R - They are formed bythe fusion of lymphocyte cell and myeloma cell
