_____ : macromolecules that store and carry genetic information
Nucleic Acids
DNA
RNA
Adenine
Types of Nucleic Acids (4) :
DNA
DeoxyriboNucleic Acid
RNA
RiboNucleic Acid
ATP
the molecule that stores the genetic information for all organisms
DNA: Deoxyribonucleic Acid:

Protein
TRUE OR FALSE: DNA does NOT act alone to pass genetic information
TRUE
FALSE
DNA is heritable:
can be passed from parent to offspring
Codes for your traits
can be passed from offspring to parent
Codes for their traits
Central Dogma of Molecular Biology:
DNA → RNA→PROTEIN
RNA → PROTEIN→DNA
PROTEIN→DNA→RNA
