Biology 111 part 2

Similarities between DNA and RNA DNA and RNA are both made of monomers and they both have 3 nitrogenous bases.
Differences between DNA and RNA RNA is a single-stranded molecule while DNA is a double-stranded RNA contains ribose while DNA contain deoxyribose RNA contains uracil while DNA contain thymine
Base Is anything that releases hydroxide ions when placed in water _pH grater than 7
Acidic Is anything the releases hydrogen ions one place it in water _pH less than 7
Nucleotides Are the building blocks of nucleic acids
Subunits of macromolecules Sugars (carbohydrates) Fats (lipids) Animo acid (protein) DNA and RNA (nucleic acids)
Four main types of macromolecules :Proteins :carbohydrates :lipids :Nucleic Acids
ATP Is the Energy currency of cells
Polymers Is a large molecule made of smaller molecules called monomers
Five nitrogenous Bases that make up DNA and RNA >Adenine >Guanine >Cytosine >Thymine >Uracil
Steroid Is a type of lipid made up of four Carborings attached to molecules that vary from one steroid to the next
The pH scale is used to measure How acidic or basic a substance is
Matter Is anything that takes up space and has mass
Buffer Prevent dramatic changes in pH
A pH of 7 is Considered neutral
The PH scale-ranges From 0 (most acidic) to 14 (most basic)
DNA is Deoxyribonucleic acid
RNA is Ribonucleic acid
Cofactors that are composed of organic molecules are called Coenzymes
Chemical Bound types from strongest to weakest Covalent Bonds- strongest Ionic Bond- Strong Hydrogen- Weak
Isotopes Are atoms that have the same number of protons but different in the number of neutrons
Atomic number Is the number of protons in the Atom nucleus
Compound Two or more elements that combine together
Radioisotopes Are Radioactive isotopes
Level of organization of a protein -Primary Structure -Secondary Structure -Tertiary Structure -Quaternary Structure
ATP is required To keep organs alive, cells are also required of energy When phosphate bond is broken energy is released
Element A pure form of matter containing only one kind of atom
Covalent bond Form between atoms that can share electrons rather than donating or reviving them
