Biotechnology Principles and Processes MCQs for NEET — Zoology Questions with Answers

Wood seasoning is not concerned with biotechnology. Biotechnology involves the use of living organisms or systems to develop or make products, whereas wood seasoning is a process of drying wood to remove moisture content.

Restriction endonucleases are enzymes that cut DNA at specific recognition sites. These enzymes are essential tools in molecular biology for gene cloning and DNA analysis.

Restriction endonucleases are enzymes that cut DNA at specific recognition nucleotide sequences known as restriction sites. They are often referred to as molecular scissors because they cleave the DNA at these specific sites, creating fragments that can be manipulated for various genetic experiments.

Bacteria are ideal for the amplification of DNA because of 2 reasons; their short doubling time; and availability extensive knowledge and tools for manipulating the bacteria. The short doubling time is advantageous because it will provide enough amounts of amplified DNA (of our interest) in a short span of time.

The Ti plasmid (Tumor-inducing plasmid) is a type of plasmid that naturally occurs in the bacterium Agrobacterium tumefaciens. This plasmid is responsible for transferring genetic material from the bacterium to the plant, causing crown gall disease. Scientists use this ability to introduce new genes into plants in genetic engineering.

For recombination to occur, DNA ligase is essential. DNA ligase is an enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. This is crucial for the ligation of DNA fragments during the recombination process.

Ti Plasmid (Tumor-inducing Plasmid) is derived from the bacterium Agrobacterium tumefaciens and is commonly used in genetic engineering to transfer new genes into plant cells. It has the ability to integrate a segment of its DNA (T-DNA) into the plant genome, making it a powerful tool for plant genetic modification.

Polymerase Chain Reaction (PCR) is a widely used technique in molecular biology to amplify a single or a few copies of a DNA segment into millions of copies. This is achieved by using a DNA polymerase enzyme to replicate the DNA in vitro, making it a crucial method for DNA analysis and research.

Restriction endonucleases are enzymes that cut DNA at specific sequences, which is a crucial step in genetic engineering. These enzymes create recombinant DNA molecules by cutting and rejoining DNA fragments from different sources.

Restriction enzymes are crucial tools in genetic engineering as they cut DNA at specific sequences, allowing scientists to manipulate and study genes. This makes the pair correctly matched.
