The function of a capsid‚ in virus biology‚ is to serve as a protective outer layer that protects the genetic material of the virus from the host’s defensive cells. The capsid is made up of proteins. The nucleic acid is what is contained within the capsid‚ which is a group of long‚ linear macromolecules‚ consisting of either DNA or RNA. There are two different cycles in which the virus uses a host cell to replicate and reproduce itself. These two cycles are known as the lytic cycle‚ and the lysogenic

Before watching the film I did not think biology had anything to do with racism. I believe scientist tried to prove that race was biological in order to justify the actions against the non-white race. I had never really thought about where race had come from but was surprised‚ but not hard to believe‚ to hear in the film that race was created by humans to describe social and cultural differences. Knowing that race is not biological will not eliminate racisms today. Those that are racist today

Ernie Reed BIO-013/ Stem Cell Research Sullivan 11.10.2010 STEM CELL RESEARCH What is a stem cell? One can define a stem cell as a cell type that is found in many tissues. This particular cell is unique in the fact that it can divide itself over and over virtually to an infinite number. This process of reproduction ensures that the cells can restore other cells that may have gotten damaged; this process may only occur if the person is still living. The same goes for animals. As the stem cell

Biology coursework The aim of this experiment is to investigate the affect of pH on the enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them

Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose‚ starch‚ maltose‚ sucrose or lactose)‚ does yeast‚ the organism containing the enzyme‚ breaks down the quickest. Introduction: Usually‚ every enzyme has a specific substrate that is what we call the “lock and key” theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration

Biology Notes Genetics Trait - distinguishing characters or phenotypic features of an individual. (e.g. Blue eyes‚ black hair‚ etc.) Purebreed - having descended from ancestors of a distinct type or breed. Purebreed organisms in a given species or variety all share similar traits. (e.g. Purebred dog.) P Generation - Designation given to the parent generation. F1 and F2 generation - First and second filial generation. First Filial Generation - offspring from the cross of the P generation.

Designer babies are genetically engineered babies where you can choose how you want your baby to look like‚ the mentality and physical traits the child will be born with. Designer babies use to be a dream in the science field but with all this fast advancement of technology it can be a high possible thing to do pretty soon. If you had the opportunity to design your own child to what you wanted‚ would you? If you ask me I would say that is wrong to do so unless it is to prevent a dieses or a disability
