Transmission of Information by DNA and RNA (My name) December 2014 GRT1 Biochemistry Task 1 DNA Replication at the Biochemical Level • A DNA (Deoxyribonucleic Acid) molecule is in comprised of two strands of nucleotides. • When DNA replicates‚ the nucleotide strands are split and used as a template for a new strand. – The original strand (template) is called the parent strand – The replicated strands are called daughter strands. – A complete daughter DNA strand contains one strand from the parent

a unique way to figure out the structure of DNA. What other scientist’s method did they decide to use and what was the method? The method Watson and Crick decided to use to figure out the structure of DNA was x-ray diffraction photography‚ which was Wilkin’s original method. Crick sends Watson to a seminar at King’s college where Rosalind Franklin speaks about her work on the structure of DNA. What is Franklin’s approach to solving the structure of DNA? How does her method differ from the approach

Extraction of DNA from Calf or Hog Thymus/Isolation of Yeast RNA I. Abstract Nucleic acids may be divided into two groups RNA and DNA. DNA contains almost all the genetic information while RNA serves as the bridge between the DNA and proteins. Study of both DNA and RNA initially involves proper extraction/isolation. The storehouse of eukaryotic DNA is the nucleus (and in the mitochondria)‚ so experimentally‚ DNA is extracted from tissues that have a high nuclear to cytoplasmic mass ratio‚ such

1 Detecting glowing E.Coli Colonies by making recombinant DNA from the lux operon of Vibrio Fischeri to pGEM. Liao‚ Tffany The marine bacterium Vibrio Fischeri produced bioluminescence effect due to lux operon transcription. The purpose of the experiment is to create a genomic library of Vibrio DNA and clone the lux operon by making Recombinant DNA and transform into another organism‚ E. Coli. Chromosomal DNA of vibrio fischeri was first extracted and digested with restriction enzyme Sal I‚ then

complementary DNA strand. Dna acts as a template because each strand becomes a daughter strand by pairing the bases. Replication happens when the helicase attaches and breaks apart the hydrogen bonds that are between the DNA strands. In the DNA polymerase‚ the enzymes copy DNA sequences by using one strand as a template. The addition of deoxyribonucleotides are caused by the reaction that happens in the DNA polymerase. The DNA polymerase needs a primer that will help with the template process. DNA is the

(first gap)‚ S (synthesis of DNA)‚ and G2 (second gap). In all 3 sub phases cell growth happens and organelles like mitochondria are replicated. DNA‚ however‚ is only synthesized during the S phase. DNA replication is started by Helicase which unwinds the double helix at replication forks. Topoisomerase is used to loosen the tension at the ends of the bubble‚ in order to correct for over winding ahead of the replication forks. Primase then synthesizes an RNA primer which the DNA polymerase III will use
