JYC: CSM17 BioinformaticsCSM17 Week 5: DNA and Genetics Genetics Cell Structure DNA Transcription (->RNA) Protein Structure
JYC: CSM17 Genetics Gregor Mendel (1865) Chromosomes –46 in humans Reproduction –female has XX –male has XY
JYC: CSM17 Cell Structure Nucleus & cytoplasm Mitochondria Chloroplasts Endoplasmic reticulum
JYC: CSM17 DNA - history Watson & Crick (1953) The double helix (like a twisted ladder)
JYC: CSM17 DNA - copying Replication DNA polymerase
JYC: CSM17 DNA - structure double helix (spiral) sugar-phosphate backbone nucleotide bases Adenine (A) Guanine (G) Cytosine (C) Thymine (T)
JYC: CSM17 Prokaryotes (simple cells) Circular DNA Mitochondria (in animals, plants, fungi) Chloroplasts (in plants) Endosymbiosis... leads to Eukaryotes
JYC: CSM17 Transcription - reading the data enzyme - transcriptase gene opens up and... messenger RNA is formed mRNA moves off through nuclear pores......to the ribosomes
MOLECULAR GENETICS. DNA- deoxyribonucleic acid James Watson and Francis Crick discover the structure of the DNA molecule DNA is a double helix (twisted.
DNA-The Double Helix Answer Key.
Classical and Modern Genetics. “Genetics”: study of how biological information is carried from one generation to the next –Classical Laws of inheritance.
C-26 Genetics Packet. What are most homologous chromosomal pairs called? Homozygous or Pure.
DNA – Deoxyribose Nucleic Acid 1. DNA is composed of a chain of nucleotides, each made up of a sugar group, a phosphate group, and a nitrogenous base.
UNIT 4 BIOLOGY Continuity and Change: Genetics and Evolution.
Protein synthesis and replication
DNA Structure The Genetic Material.
Biology 12 – the nucleus. Cell structures Is this eukaryotic? yes Why? nucleus Is this a plant or animal cell? animal Why? No cell wall or chloroplasts.
4.1 The Function of the Nucleus within the Cell
DNA REVIEW. The connecting pieces or “rungs” on a DNA ladder. NITROGEN BASES.
DNA Structure and Function
DNA Deoxyribonucleic Acid. The DNA Connection What have you learned about inheritance, DNA, and cell division up to this point? How do genes determine.
8.1 DNA Structure & Function. Nucleic Acids DNA & RNA are nucleic acids Monomer? ▫Nucleotides 5-C Sugar P N- Base.
Watson and Crick Watson and Crick studied the work of others to determine the structure of DNA Figured that it is a “Double Helix”: –Twisted ladder.
Transcription Protein Synthesis Part 1 pp
DNA and now RNA DNA is deoxyriboneucleic acid. RNA is ribonucleic acid.
Mrs. Degl Molecular Genetics DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a.
DNA. DNA History Hershey-Chase – Concluded that the genetic material in bacteria was DNA not proteins Watson & Crick – created the double helix model.
