Layers of complexity
in life's order.
Bottom of the stairway of organic order.
subatomic: quarks, leptons, bosons
atomic: neutrons, protons, electrons - Atoms
elements: C, H, O, P, K, I, N,
S, Ca, Fe, or
H2O (water) or CO2 are compounds
bases: adenine = thymine; guanine
helix shape of DNA & RNA molecule in which three bases code for an amino acid (21)
the sequence of N bases = sequence of the amino acids & the sequence of amino acids = protein, hormone, enzyme
sequences of DNA or RNA = traits on chromosomes
base sequences code for amino acid, the building
blocks of proteins.
Proteins, catalysts, hormones;
the micro machinery of life.
mitochondria & chloroplasts have their own DNA
have DNA in organelles: packed into the nucleus if these are
- Biotic Communities
- Biophysical Region
