One method is to microinject deoxyribonucleic acid (DNA) into eggs; another method is to use vortex mixing to create tiny holes in the eggs through which DNA enters.
<h3>Process of gene transfer</h3>
Genetic engineering techniques are steps that are taken to create a genetically modified organism that can be used for studies. This technique involves the following major steps:
- Isolation of DNA fragments from a donor organism,
- The insertion of an isolated donor DNA fragment into a vector genome; and
- The growth of a recombinant vector in an appropriate host.
The insertion of an isolated donor DNA fragment into a vector genome can be done through microinjection method or vortex mixing.
When eggs are used as vector genome, microinjection of DNA can be carried out or vortex mixing can be used to create tiny holes in the eggs through which DNA enters.

An example of <span>nonsubstituted alkane that can exist as one of only two isomers is Butane with molecular formula </span>
<span>.</span>
Isomers are those having the same molecular formula but different chemical structure.
Non-substituted alkane means it is not substituted by any other atom.It has only carbon and hydrogen atoms attached to it.
Correct answer: C). Evolution by natural selection, Galapagos finches
Charles Darwin gave the theory of natural selection in the year 1835 when he visits Galapagos Islands.
There he found several species of finches are adapted to different environmental niches. They have a different shape of the beak, food source they eat and the way they captured the food.
He observes that species vary from island to island, and based on these observations he gave the theory of natural selection.
