PPT-KEY CONCEPT DNA replication copies the genetic information of a cell.

Warm up What makes the new DNA strand complementary to the original strand Vocabulary tip Compl e ment either of two parts that completes a . DNA is made of long chains of . nucleotides. each nucleotide has 3 parts:. 1. . deoxyribose. . sugar. 2. . phosphate group. 3. . nitrogenous base.  . DNA Components. there are . 4. possible nitrogen bases:. Chapters 12 & 13. The Role of dna. Stores Information. Keeps the instructions that make you look and act the way you do. Copies Information. During cell division you have to copy the DNA before the cell can split. Biology: Unit 6 Part 2. What is DNA?. DNA = Deoxyribonucleic Acid. Contains information needed for the cell’s growth and other activities.. Determines the inherited characteristics of an organism.. BIO…. LIFE….. THINK ABOUT THIS: . What do we do in our lifetime?.

Nucleic acids represent a prominent . category of biomolecule . present in living cells. The . term incorporates . both DNA and RNA. DNA represents the repository of genetic information (. Genetic engineering involves inserting foreign genes or modifying the activity of existing genes. . This technology exploits the process of gene cloning which involves making many identical copies of a gene. . 1. OVERVIEW. 2. By the 1940’s, scientists knew that chromosomes carried hereditary material and consisted of DNA and protein..

The building blocks of DNA are nucleotides. Each nucleotide is made up of a sugar, a phosphate group, and a nitrogenous base. The sugar is deoxyribose in DNA and ribose in RNA.. Presentations.
