(DNA)Stores heredity info in genes by way of genetic code. · Code is determined by arrangement of nucleotides (4 types; A,T,C,G) (RNA)Helps translates and assemble proteins **__ 2 types of Nucleic Acids: (RNA & DNA) __** 1. RNA 3 types (r_________ rRNA, t_________, tRNA & m___________mRNA) 2. DNA: forms the genetic code RNA single strand ** Proteins (CHON) + various functional groups ** amino acids (20) Protein same basic structure **instructions for arranging amino acids into different combinations is in DNA** 1. **__Enzymes__**: control the rate of reactions & help digest food. 2. **__Structural proteins__** - form skin & muscles 3. **__Transport proteins -__** embedded in cell membrane allow substances passage into & out of cells 4. **__Defense proteins__** - antibodies which fight infection
