Nucleic Acid Basics Contain instructions to build proteins 2 types: – DNA – RNA Composed of smaller units called nucleotides – Monomer: Nucleotide – Polymer: Nucleic acid
Nucleotide Structure Three parts – Sugar molecule – Phosphate group – Nitrogen base (A, T, C, or G) Nucleotides combine to make nucleic acids Nucleotide arrangement determines protein created
Monomers link to make polymers! Nucleic Acids Monomer = Nucleotide Polymer = Nucleic acid How many nucleotides are pictured? Six What is this chain of nucleotides called? Nucleic acid
DNA Double Helix: 2 chains of nucleotides Four DNA bases: Adenine, thymine, cytosine, guanine – A pairs with T – C pairs with G DNA stores the info required to make a protein Gene: section of DNA that codes for a protein T C G A C
Predict the nucleotides to fill in this DNA chain
RNA Single chain of nucleotides RNA bases: Adenine, uracil, cytosine, guanine Job: – 1) Make a copy of the DNA code – 2) Deliver the copy to a ribosome – 3) Ribosome assembles the protein U A C U G
NUCLEIC ACIDS : DNA and RNA Nucleic Acids Very Large, Complex, DNA & RNA Store Important Info in the Cell. (Genetic Information) ATP is an energy carrier.
Nucleic Acids Not considered a nutrient macromolecule
Nucleic Acids The amino acid sequence of a polypeptide is programmed by genes. Genes consist of DNA, which is a polymer belonging to the class of compounds.
– Carbohydrates – Lipids (fats) – Proteins – Nucleic Acids Organic molecules are the molecules in living things There are four types of organic (carbon-based)
Nucleic Acids. Elements Nucleic Acids Contain C, H, O,N, P.
Family Resemblances Why do siblings often look alike?
Nucleic Acids Organic Molecules: Carbohydrates Proteins Lipids Nucleic Acids.
Nucleic Acids Nucleic Acid Basics Contain instructions to build proteins 2 types: – DNA – RNA Blueprint to build a car Protein built from DNA instructions.
Nucleic Acids Nucleic Acid Basics Contain instructions to build proteins 2 types: – DNA – RNA Composed of smaller units called nucleotides – Monomer:
Nucleic Acids -DNA and RNA
How DNA helps make you you. DNA Function Your development and survival depend on… Your development and survival depend on… which proteins your cells.
DNA The Structure of DNA. What does the DNA of all these organisms have in common? They all share a universal genetic code.
Date DNA. ✤ DNA stands for deoxyribonucleic acid ✤ DNA carries all the genetic information of living organisms.
