Bacteria Section 19–1 This section describes two groups of prokaryotes and explains how they differ. It also explains what factors are used to identify prokaryotes. Introduction What are prokaryotes? They are single-celled organisms that lack a nucleus. Introduction

Intro to DNA DNA = Deoxyribonucleic acid -double polymer of nucleotides -SS chromosomes contain 1 molecule of DNA (re: double polymer of nuc’s) -after DNA replication, a DS chromosome contains 2 complete polymers of DNA

What is DNA? Pages 110 - 117 DNA 3 What is DNA? A cell uses a code in its hereditary material . The code is inside a molecule called deoxyribonucleic acid, or DNA . The DNA contains information for an organism’s characteristics, traits, growth and function. DNA 3 What is DNA?

Nutrition. Thinking Questions. Essential amino acids are found in eggs, milk and cheese. Grains also supply many needed amino acids. . Can a person be healthy if he or she chooses not to eat meat?. Can a person be healthy if he or she chooses not to eat meat?.

Peptides and Proteins. Classification (vague). Peptides have fewer than 50 amino acids Oligopeptides (di, tri-, tetra-, etc.) up to about 10 aa Polypeptides (longer chain of aa than an oligopeptide)

DNA, RNA, & Proteins. The shape of DNA. A DNA molecule is shaped like a spiral staircase and is composed of two parallel strands of linked subunits. The spiral shape of DNA is known as a double helix. Each strand of DNA is made up of linked subunits called nucleotides.

SCIENCE 10 LIFE SCIENCE: GENETICS.  Genome British Columbia, 2004 www.genomicseducation.ca. I. How does the genetic code relate to the assembly of different proteins?. I. How does the genetic code relate to the assembly of different proteins?

Special Note: Endothermic Reactions. As long as the total entropy is slightly positive, endothermic reactions will go forward Spontaneity is determined by the increase in the entropy of the system, NOT a decrease in the ENERGY (heat) of the system!. . Equilibrium.

*** Amino acid: building block for protein, protein may contain a chain of several hundred amino acids Molecular weight of 2-3,000 Amino acids contain an acid group and an amine group Amino acids are bonded together by peptide bond

Fingerprints. Summary. What are fingerprints? How are fingerprints analyzed? How are fingerprints collected?. Fingerprints. What are fingerprints?. Friction ridge skin pattern. Found on fingers, palms, toes, soles of feet. Composed of ridges (hills) and furrows (valleys). Black = Ridges

Leaving Certificate Agricultural Science. The Digestive System. Enzymes. Enzymes are biological catalysts. They are natural substances, which speed up the breakdown of food substances and other materials. They work by combining with the substrate forming the enzymes – substrate complex .

The Alimentary Canal. Standard Grade Biology. Can you sort out the statements into True and False?. Carbohydrates, proteins and fats are all made up of carbon, hydrogen, nitrogen and oxygen. Fats are made up of smaller units called amino acids. Starch is a large carbohydrate molecule.
