PPT-Five Strands of Social Studies

What is Social Studies The study of how people over time have interacted with each other and their environment In social studies we have five strands of social studies A strand is an area of study . Strands in Pragmatics CHAPTER ONE...................................................................................5 PRAGMATICS:......................................................5 WITTGENSTEIN... The Role of . dna. in Heredity. Stores information needed for traits and cell processes. Copying information needed for new cells. Transferring information from generation to generation. Griffith’s Experiments. . Spring 2014 Pilot. Webinar #1. h. . Broadcast: Friday, April 11. 4:00 – 5:00 p.m.. Webinar . Overview. In this webinar, we will be focusing on:. Photo Release Forms. Compiling. an Evidence Collection by S. The amino acids in their natural habitat. Topics:. Hydrogen bonds. Secondary Structure. Alpha helix. Beta strands & beta sheets. Turns. Loop. Tertiary & . Quarternary. . Structure. Protein Domains. MONDAY: Study the “old dead people” from this unit!. TUESDAY: . QUIZ. on DNA structure. WEDNESDAY:. THURSDAY:. FRIDAY: . TEST. —DNA . DNA Structure. What the heck is DNA made of?. Erwin Chargaff. Objectives:. 1. Summarize the roles of the different enzymes involved in replication of DNA.. 2. Explain how the leading and lagging strands are replicated differently . Semiconservative. Replication. The function of DNA in the cells is to. preserve genetic information.. transfer genetic information to new cells as the strands of DNA are copied.. DNA Replication. In . DNA replication. ,. the strands in the original or parent DNA molecule separate to allow the synthesis of complementary DNA strands.. COMP308. I believe things like DNA computing will eventually lead the way to a “molecular revolution,” which ultimately will have a very dramatic effect on the world. . L. . Adleman. Presentation Outline. THINK ABOUT IT. The DNA molecule must somehow specify how to assemble proteins, which are needed to regulate the various functions of each cell.. What kind of structure could serve this purpose without varying from cell to cell?. 1. Griffith . - . Transformation . Since Morgan showed that genes are found on chromosomes, . the new issue was whether the genetic material was in the proteins of the chromosomes or the DNA. . Most thought the . Learning . Goal . Describe the double helix of DNA and the process of DNA replication.. DNA Base Pairs. During the 1940s, biologists determined that the bases in DNA had a specific relationship:. the amount of adenine (A) was equal to the amount of . In . their 1953 announcement of a double helix structure for DNA, Watson and Crick stated, . "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.". RNA. RNA. Protein. Protein. Scientists call this the:. Central . Dogma. of . Biology!. Part 1: DNA Structure and Replication. What is DNA?. DNA = . D. eoxyribo. n. ucleic . A. cid. It is the blueprint for life – it is the molecule which stores genetic information in ALL living things. What is fiber optics. Fiber optics is simply strands of flexible glass as thin as human hair that is used for telecommunications. .. These strands carry digital signals with . light.. When hundreds or even thousands of these strands are arranged in bundles, it is called an optical cable..
