Name: Anna Tran Date: August 7‚ 2015 Student Exploration: Building DNA Vocabulary: double helix‚ DNA‚ enzyme‚ mutation‚ nitrogenous base‚ nucleoside‚ nucleotide‚ replication Gizmo Warm-up The Building DNA Gizmo™ allows you to construct a DNA molecule and go through the process of DNA replication. Examine the components that make up a DNA molecule. 1. What are the two DNA components shown in the Gizmo? Nucleosides and phosphates 2. A nucleoside has two parts: a pentagonal sugar (deoxyribose)

Proteins play an important role in the human body. The DNA molecule controls the synthesis of proteins. The DNA contains genes which are sequences of nucleotides and bases. Proteins are used for growth and repair. Proteins are made up of amino acids linked together by peptide bonds. Firstly ’amino acid synthesis ’ is the set of biochemical processes by which the various amino acids are produced from other compounds. The substrates for these processes are various compounds in the organism ’s diet

protein coat that surrounds the core of DNA. When phage DNA enters the host cell it directs phage reproduction. DNA is the molecule that is responsibility for heredity. In this experiment‚ phage was added to E.coli in a radioactive medium. Phages were used to demonstrate that DNA is the genetic material. The DNA molecule is surrounded by a protein coat. So‚ when phages infect bacteria‚ they will attach to the surface of the bacterium. When this happens‚ they inject DNA into the cell. The protein coat remained

CRISPR is a new technology‚ a method that can edit genomes. It makes it possible for scientists to manipulate and make changes to the DNA in the cells of all organisms. Since this is such a new discovery‚ there hasn’t been done much testing and experimenting‚ which makes it unknown and none predictable for humans. It is said that with CRISPR‚ scientists will for example‚ be able to change genes in human embryos‚ and create so called “designer-babies”. There has been a lot of discussion around this

later‚ another 15-year-old girl was raped and murdered. DNA fingerprinting of DNA samples from suspects and the crime scene - Proved one man guilty and another man innocent. Recombinant DNA Technology Recombinant DNA technology is a set of techniques for combining genes from different sources into a single DNA molecule. (Figure 1) - An organism that carries recombinant DNA is called a genetically modified (GM) organism. Recombinant DNA technology is applied in the field of biotechnology.
