Central Dogma of Biology
Code on DNA transcribed into RNA which is then translated into Protein that determines traits
Protein determines the trait
Gene - Information to make RNA
Nucleic Acid Structure (DNA/RNA)
Nucleotide - the letters
phosphate
nitrogenous base
Sugar

Rules of Complementarity
sum of the probabilities of an event and its complement must equal 1.
Replication
copies all dna
Types of RNA
tRNA
rRNA
mRNA
Encodes amino acid sequence of a polypeptide.
Brings amino acids to ribosomes during translation.
With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
Starts as enzyme
Starts during Synthesis phase of the eukaryotic cell cycle
