following can be used to carry foreign DNA into host cells

b. Virus

d. Plasmids

e. Lipid clusters

f.Blasts of pellets

Transgenic animal and plant can pass a foreign gene to offspring.

c.a and b

Explanation:-

during electrophoresis biomolecules like DNA ,RNA,Proteins are separated on the basis of their charge, size, shape. Origine of DNA or its sequence or composition does not matter in electrophoresis.

we can edit and insert our gene of interest in virus without affecting its infection ability, virus integrate its genome in host cell so that it is easy to transfer our gene in host cell. example of virus is λ bacteriophage

plasmid - a extrachromosomal DNA of bacteria also used for DNA dilevery in host, clusters of lipid or liposomes which are sphere of lipid also used for DNA transformation. pelletes or DNA coated Small particles of gold or tungsten are used to direct transfer of DNA into host cell.

transgenic organisms are those organism which carry foreign DNA sequence in it, these transgenic organism like animal or plant can transfer these gene or DNA to their offspring if the transformation is in their germ cell line, or plant which can propagate asexually also transfer transgenic DNA in next generation

In genetics when using gel electrophoresis there are many decisions. If you want to separate fragments that are very close in size you should use a higher percentage of agarose. The power supply has two settings for voltage, 120V or 160V. It also has a timer that has 2 settings 15 minutes and 90 minutes. If you would be running whole genomic DNA samples you recently extracted and the fragments would be about 30 kb in size. If performed a number...
