Chromosomes from different parents determines the genetic structure of the child (from both parents) only with recessive genes ONLY becoming apparent if they are present in BOTH parents<span />
<span>DNA replication involves unzipping the DNA molecule, followed by base pairing, which adds complementary nucleotides, to form two new identical DNA molecules that move to the new cells during cell division.</span>
B) is the correct answer. The flu virus does not have the same genetic makeup each year as with each individual it infects its rapidly mutating.
Nucleic acids also typically contain phosphorous, and nitrogen plays an important structural role in nucleic and proteins. The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium.
