Nucleotides

Label the DNA molecule.

[blank_start]Adenine[blank_end] - [blank_start]2[blank_end] Hydrogen Bonds - T[blank_start]hymine[blank_end] C[blank_start]ytosine[blank_end] - [blank_start]3[blank_end] Hydrogen Bonds - [blank_start]Guanine[blank_end]

DNA has:

1. [blank_start]DNA Helicase[blank_end] breaks the [blank_start]Hydrogen Bonds[blank_end] between the bases. 2. The Helix unwinds. 3. Free-floating [blank_start]DNA Nucleotides[blank_end] are attracted to the now-exposed bases and form Hydrogen Bonds with their [blank_start]Complementary Base Pair[blank_end]. 4. [blank_start]DNA Polymerase[blank_end] catalyses [blank_start]Condensation[blank_end] Reactions to form [blank_start]Phosphodiester Bonds[blank_end] between the new Nucleotides on both strands. 5. The two new strands separate.

DNA Polymerase can only travel in the 5' to 3' direction because of the shape of its Active Site.

Which experiment showed that DNA replicates Semi-Conservatively?

Label the RNA molecule

Which Base is present in DNA but not in RNA?

RNA is shorter than DNA and has one strand.

Label this ATP molecule

Ribose and Deoxyribose are Pentose Sugars.

ATP is known as a Nucleotide Derivative.

Label this diagram.

ATP Hydrolase performs a [blank_start]Hydrolysis[blank_end] Reaction to [blank_start]break off[blank_end] a Phosphate Group. ATP Synthase performs a [blank_start]Condensation[blank_end] Reaction to [blank_start]add on[blank_end] a Phosphate Group.

ATP is formed during Respiration in the Golgi Apparatus.
