What cellular events occur in the G1 phase of the cell division cycle? - normal growth and cell function What is the best way to describe homologous chromosomes? - they carry information for the same traits In some parts of Africa, the frequency of individuals who are heterozygous for the sickle-cell anemia allele is higher than the frequency in North America, presumably because this reduces the frequency of malaria. Such a relationship is related to what? - Darwin's theory of natural sel...

Guanine - ans --Base that pairs with cytosine in RNA RNA - ans --Nucleic acid responsible for using genetic information to produce proteins DNA - ans --Nucleic acid built from nucleotides Z-form helix - ans --DNA structure stabilized mainly by hydrogen bonds Ribose - ans --Pentose sugar constituent of mRNA Purines - ans --Bases with one ring and two nitrogen atoms (adenine and guanine) Pyrimidines - ans --Bases with one ring and one nitrogen atom (cytosine, thymine, and uracil)...
