In chapter 11‚ we learned about DNA and Genes (11.1DNA: The Molecule of Heredity; 11.2From DNA to Protein; 11.3Genetic changes). DNA (deoxyribonucleic acid)‚ which is in a shape called a double helix‚ developed its name from the simple sugar in DNA (deoxyribose). The phosphate group is composed of one atom of phosphorus surrounded by four oxygen atoms. A nitrogen base is a carbon ring structure that contains one or more atoms of nitrogen. Next to cover is DNA replication in which enzyme breaks

the polymer is DNA. If the sugar is ribose‚ the polymer is RNA. Together with proteins‚ nucleic acids are the most important biological macromolecules The two nucleic acids used in repair‚ reproduction and protein synthesis are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). RNA maybe found throughout the cell II.CLASSES DEOXYRIBONUCLEIC ACID (DNA) nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms DNA is usually found

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.

Lab manual/results/online article condensed notes Lab 1 · DNA is made up of deoxyribonucelotides · Components of DNA/RNA includes a 5 carbon sugar‚ a phosphate group‚ and a nitrogenous base · the negative charge associated with DNA/RNA is due to the phosphate groups · DNA is linked together by phosphodiester bonds (they are covalent bonds) · the energy required to create these bonds is from the cleavage of pyrophosphate‚ refer to figure 1.3 on page 4 and below. ·

double stranded DNA ¡VdsDNA). The DNA of the phage contains around 50‚000 base pairs and codes for 50 proteins. At both ends of the DNA of the phage‚ there are cohesive ends‚ which are composed of 12 nucleotides. Both ends compliment each other‚ which makes the DNA circular once together. This circular DNA is usually present in an infected bacterial cell. This protects the DNA to be degraded by the cell. In this laboratory experiment‚ restriction enzymes were used to analyze the DNA of the lambda

Hershey and Chase Experiment In 1953‚ Alfred Hershey and Martha Chase confirmed DNA’s preeminent role in genetics by demonstrating that DNA is the genetic material of a virus called phage T2. The phage‚ which infects E. coli‚ consists of a head‚ sheath‚ tail‚ and base plate made of different proteins. DNA is packaged within the head of the virus. When T2 comes in contact with E. coli‚ the phage attaches to the bacterium by its tail. Next‚ the phage injects genetic material into the cell. The genetic
