16 - The Molecular Basis of Inheritance Ch. 16: The Molecular Basis of Inheritance Concept 16.1: DNA is the genetic material Early in the 20th century, the identification of the molecules of inheritance loomed as a major challenge to biologists When T. H. Morgan?s group showed that genes are located on chromosomes, the two components of chromosomes?DNA and protein?became candidates for the genetic material A chromosome consists of a DNA molecule packed together with proteins The bacterial chromosome is a double-stranded, circular DNA molecule associated with a small amount of protein Eukaryotic chromosomes have linear DNA molecules associated with a large amount of protein In a bacterium, the DNA is ?supercoiled? and found in a region of the cell called the nucleoid

Gavin Morgan 9/11/2015 Chapter 3 2-Point Notes Carbon: The Framework of Biological Molecules Functional groups account for differences in molecular properties: 1. Carbon and hydrogen atoms have similar electronegativities, therefore, their electrons are evenly distributed. 2. Other molecules are polar, which causes other molecules to attach. Isomers have the same molecular formulas but different structures: 1. Isomers have the same molecular formula but exist in different forms. 2. Enantiomers are isomers that are mirror images of each other. Biological macromolecules include carbohydrates, nucleic acids, proteins, and lipids:

AP Biology: DNA Replication Lab You will use simulations to demonstrate the structure and replication of DNA in this laboratory exercise. As you have studied, the genetic information for living organisms is stored in the structure of deoxyribose nucleic acid (DNA). Our DNA molecules carry the genetic code for inherited characteristics in the triplet-coded sequences of its nitrogen bases. Each time a cell divides, its DNA is precisely duplicated (DNA replication) so that the DNA of the cells formed is identical to that of the original cell.

DNA, RNA, and Protein Synthesis DNA -The species-particular DNA sequences produce the species-particular proteins -Genes code for proteins -Genes are long strands of DNA of chromosomes WHAT IS DNA? -DNA is genetic code -Instructions for heredity -Components of genes -Director of protein synthesis -A type of nucleic acid -A type of organic compound -A polymer {a compound made of repeating subunits} DNA'S PROPER NAME IS -Deoxyribonucleic acid -Consists of a ribose sugar with a "missing oxygen" (thats the de-oxy part) -And it's found in the nucleus of eukaryotic cell STRUCTURE OF DNA -A nucleotide of DNA is the base unit -A nucleotide consists of a phosphate, a sugar, and a nitrogen base DNA IS A DOUBLE STRAND -The nitrogen bases have compliment partners

4/2/13 1:14 PM DNA Deoxyribose Double Stranded (Double Helix) Nitrogenous bases (Cytosine, Guanine, Adenine, Thymine) RNA Ribonucleic Single Stranded Nitrogenous bases (Cytosine, Guanine, Adenine, Uracil) Both have phosphate Cytosine = Guanine Adenine = Thymine DNA Replication is semi conservative. DNA Replication happens during interphase. One strand determines the sequence of the other strand. DNA polymerase copies DNA strands in the 5?->3? direction. Transcription ? The first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme, RNA polymerase. Translation ? The process through which cellular ribosomes manufacture proteins. In DNA, T=A G=C In RNA, T=A G=C A=U Translation occurs in the cytoplasm.
