Once dna was shown to be the primary genetic material of life, a race among scientists took place to work out its structure. which concept came from studying the amounts of each dna base in different organisms? a. codon-amino acid pairings b. double helix structure c. complementary base-pairing d. the relationship between dna and rna

the answer to your question is:

c. complementary base-pairing

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
