Question

Gene library consists of
(a) All fragments of a genome
(b) Frozen germplasm
(c) Tissue culture
(d) Living bacteria having clones of genes

Answer 1

Hint: This is the collection of DNA fragments that contains all the features of an organism

Complete answer:
A molecular biology technique that makes many identical copies of a piece of DNA, such as a gene is known as DNA cloning.
During a typical cloning experiment, a target gene is inserted into a circular piece of DNA for cloning experiments during typical cloning experiments. This targeted gene is called a plasmid.
The plasmid is introduced by the process of transformation into bacteria and bacteria carrying the plasmid are selected using antibiotics.
Bacteria with the correct plasmid are used to make more plasmid DNA and also in some cases induced to express the gene and make protein.
- A genome is the genetic material of an organism according to the field of molecular biology or genetics. It generally consists of DNA (or RNA in RNA viruses).
- The genome includes both the genes (the coding regions) and therefore the noncoding DNA also as well as mitochondrial DNA and chloroplast DNA.
- Germplasm contains the information for a species' genetic makeup that is considered to be a valuable natural resource of plant diversity.
- A method of scientific research during which fragments of tissue from an animal or plant are transferred to a manmade environment is known as tissue culture. During culture, they will continue to survive.
- A single cell, a population of cells, or a whole or part of an organ can be present for tissue culture.
So, the correct answer is ‘living bacteria having clones of genes’.

Note:
1. A Gene library is also called a gene bank.
2. The study of the genome is called genomics.
3. A living tissue from which new plants can be grown is known as germplasm.
