* Cell Respiration & Photosynthesis Cycle
All living organisms do some form cell respiration.

Only producers do photosynthesis.

* Cell Division and Cancer
Nucleotides are the monomers of DNA

Four DNA nitrogenous bases:
Adenine -> Thymine
Cytosine -> Guanine

** Cell Division & Cell Cycle
stem cell - cells form which specialized cells are generated

apoptosis - programmed cell death

balance between generation and death

Interphase
G1 -> S -> G2

** DNA Replication during S of interphase
DNA is "unzipped"; hydrogen bonds between base pairs break
Single-stranded DNA used as a template
Base pairing rules followed
DNA Polymerase is the main enzyme of DNA replication
Semi-conservative replication

** Anatomy of a Chromosome
chromoseome: double-stranded DNA wound around proteins
sister chromatids: identical double-stranded dna molecules that result from DNA replication
