1: Showing the beginning of the DNA replication process Diagram 2: Showing the leading and lagging strand and the direction they replicate. Also showing Okazaki Fragments, and the 3” to 5” end of DNA. The arrows in the above diagram show the 3” to 5” direction that the DNA replicates; starting in the origin of replication and moving towards the 5 direction, using Okazaki fragments in the Lagging strand. Diagram 3: Showing a more detailed version of DNA replication. Showing the enzymes

Gattaca is a movie directed by Andrew Niccol and the film is set in the "not too distant future." Andrew Niccol's perception of the future isn't what most people expect, but once thought about carefully it seems quite believable. This movie presents us with a new method in which society strives for perfection and it also makes us wonder if genetic engineering is morally correct. Your place in society in Gattaca is based on your genetic makeup and the way you were born. People born the way we know

Isolation and identification of cyanobacterial samples Cyanobacterium was isolated from the jhum land soil (25°10/22.9//N and 93°07/10.9//E at an elevation of 600.9 m) of Dima Hasao district of Assam, North-East India in BG-110 media (Rippka 1979) without supplementation of combined nitrogen. The isolated cyanobacterium was identified as Nostoc muscorum Ag. ex Born. et Flah. using the key mentioned in Desikachary (1959). Biomass production using organic manure Media was optimized for cyanobacteria

Introduction Mids-1600s and an English scientist named Robert Hooke made observations. He observed strands of fungi among the specimens of cell his viewed. Robert Hooke in 1665 reported that living things were composed of title boxes or cells. He then devised the compound microscope and illumination system and stated that microbes were a life’s smallest structural units were cells. Then in 1670s, decades after, Dutch merchant named Anton van Leeuwenhoek made careful observations of microscopic organisms

Nanotechnology is introduced in 1980’s by which it is possible to build things at nano scale by controlling molecules at atomic level. In later years technology has accepted and improved and found its use in various fields including electronics, organic chemistry, biomaterials, medicine etc. Nanomedicine uses this nano scale particles for the benefit of mankind (Medina et al., 2007). Using these nano particles therapeutically has made a significant improvement in the field of medicine that is used

cells in petri dishes, trying to clone cells and mutate them. Scientists have even figured out how to change human DNA before it's even born. Doing so allows them to change physical features, abilities, and prevent certain diseases such as alzheimer's. I imagine that genetic engineering is very helpful and could potentially further our society. However, it is illegal to change or mutate DNA in a child in the US. Specifically modifying or editing gene cells or embryos so that a child has certain features

Information and Transform with DNA and RNA Shelley Gutierrez, RNC Western Governors University Student ID: 391502 Sgutie6@wgu.edu How Cells Transmit Information and Transform with DNA and RNA All of our body cells are made up of 46 chromosomes. Each of the 46 chromosomes contains one DNA molecule. These chromosomes and proteins are found compressed in the nucleus of the cells. DNA and RNA are biological molecules that are nucleic acids. Both DNA and RNA are polymers. When

as “a cell whose DNA is enclosed in a nucleus and associated with proteins and contains membrane-bound organelles”. Prokaryotic cells are defined as “a cell in which the DNA is loose in the cell; eubacterial and archaebacterial cells prokaryotic. Prokaryotic cells generally have no internal membranous organelles and evolved earlier than eukaryotic cells”. The eukaryotic cell and prokaryotic cells are alike in many ways. For example, they both have DNA as their genetic
