Given that the dna molecules all have similar charge to mass ratios, what property do you think is most important in determining migration in the gel?

The answer is size. The larger the DNA molecule the slower it travels through the gel.  This is because of the restriction of their movement through the pores of the gel. The smaller DNA molecules travel furthest. The size of the pores can be varied through by changing the mixture ratios of the agarose gel.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
