Answer 1
Gene refers to the unit of heredity that is made up of DNA, which occupies a specific
position on the chromosome. A gene can be defined as molecular units of heredity, present in all
living organisms. The genes have the primary function of storing relevant the information that
helps to maintain and build the cells in an organism, thereby subsequently transferring the
genetic traits to their offspring. In other words, genes act as heredity elements that help in
determining the characteristic features or traits that are inherited from the parents during
reproduction. On the other hand, a genome is defined as group of all genes that are comprised of
haploid set of chromosomes. The genome refers to the complete set of DNA present in an
organism, including all the genes (Xiwen, et al. 90;157-166). It is primarily composed of DNA
and RNA (in case of viruses). All genes along with the non-coding regions are present in the
genome of an organism.
A specific gene is isolated in biotechnology when cloning experiments are performed.
The process of recombinant DNA technology that involves crop resistance includes the
procedure of isolating genes from plants that produce Bt protein.
The genome is isolated in biotechnology during sequencing for the bacterial isolate
genome database.
