Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA, can you use it to predict the amounts of all four nucleotide bases when you only know the amount of one type of base? Approximately 21% of the human genome is comprised of nucleotides containing C. Given this information, calculate the percentage of the human genome that is comprised of nucleotides containing G, T, and A. a. % of the human genome is comprised of G.
b. % of the human genome is comprised of T.
c. % of the human genome is comprised of A.

a. 21% G

b. 29% T

c. 29% A

Explanation:

Based on Chargaff's rule, we know that A = T and C = G.

.21 C => .21 G

.21 + .21 = .42

So we know all the C and G is .42. So what's left must be the A and T.

1 - .42 = .58

There's .58 A and T, so divide that in half, because they're equal amounts.

.58/2 = .29

.29 A => .29 T

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
