1. How do living cells use the instructions in their DNA to perform tasks?

By undergoing Gene expression (transcription and translation)

Explanation:

The deoxyribonucleic acid, DNA is the nucleic acid that stores genetic material in living organisms. It contains segments called GENES that carry information for the synthesis of useful products used to perform tasks in living organisms called PROTEINS.

However, the information in these genes need to be expressed by the processes of transcription and translation. Transcription involves the synthesis of mRNA from a DNA molecule while translation involves synthesis of proteins (amino acid chain) from mRNA.

The proteins are the biomolecules that carry out the tasks in living organisms as hormones, enzymes etc.

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.

i believe it is c: genes for body color and wing size are inherited separately from each parent.
