DNA+and+Replication+Notes

[|DNA Song]

DNA and Replication (Two column notes) 1. Nucleotides are very long organic molecules made of C, H, O, P, N. 2. Nucleotides contain the instructions that cells need to carry out all functions of life. 3. DNA and RNA are the two kinds of Nucleotides 4a. The genetic material that carries information about an organism is made of DNA. 4b. DNA carries genetic information from parents to offspring 5. The information in DNA is used to direct all the activities of the cell. 6. m-RNA and t-RNA are involved in making proteins. 7. DNA is made of two long strands shaped like a twisted ladder. 8. Pieces of DNA in the nucleus are called chromosomes. 9. Pieces of DNA are wound tightly around proteins to for chromosomes. 10. Alternating sugar and phosphate molecules make up the two sides of the DNA ladder. 11. Each rung of the DNA ladder is made of a pair of molecules called nitrogen bases. 12. DNA has four kinds of nitrogen bases represented by the letters A, T, G, C. 13. The bases on one side of the ladder pair with the bases on the other side. 14. A only pairs with T and G only pairs with C. 15. The process of replication makes two identical copies of the DNA. 16. One copy of the DNA goes into each daughter cell during Mitosis. 17. Replication starts with the “unzipping of the DNA ladder. 18. Next new bases pair up with the bases on each half of the unzipped DNA Ladder to make two ladders.
