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

ad‚ some might think it’s ridiculous or might take insult. No matter what everyone has a opinion but what is the difference in opinions or thoughts? What do you think of the phrase on this ad‚ Together We Make Football Bold. They’ve hidden the true meaning between the phrase in the ad‚ “Together We Make Football Bold” and the New York Giants shirt the women wears. But as I’m looking at the page it occurs to me that the lady has darker skin than others may have. In the middle of the page she stands

Cellular organelle structure and function Nucleus The Nucleus is comprised of the pore perforated nuclear membranes‚ nucleoplasm‚ chromatin and the nucleolus at the core. The nuclear envelope consists of an inner and outer membrane that forms the outer structure. Contained within the nuclear membrane are nucloplasm which is the fluid medium in which the chromatin is present‚ chromatin being the genetic material. At the core of the nucleus is the nucleolus‚ where ribosomes are synthesized. The

The nucleus is a large membrane bound organelle. Most cells have a single nucleus though skeletal muscle can have more than one (multinucleate) or some cells such as red blood cells have no nucleus. The nucleus contains the genetic material and is where DNA replication and RNA transcription occur. The nucleus is bound by a membrane which contains nuclear pores. These pores allow RNA molecules and proteins to move in and out of the nucleus. However‚ this process is selective and is energy dependent

molecules DNA and RNA‚ which are found in all living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains

have an impact on the workplace and home. However there are also some disadvantages for both of them. This essay will describe gender roles at work and in the home with reference to Japan. Firstly‚ many women are distressed by the balance between home and work. They face “role overload” ‚which means trying to merge the roles of worker and mother or wife. When both spouses work outside‚ women tend to do the “lion’s share” of the housework. For example‚ an Australian research showed that working

How the structure of proteins are related to their functions Rachel Morris The basic building blocks of proteins are amino acids‚ the biuret reaction tests for protein. A solution of sodium hydroxide is added to a sample then a few drops of copper sulphate solution‚ if positive – the solution will turn mauve. There are 20 different amino acids and they can be joined in any order. Therefore there can be many different functions. A protein consists of one or more polypeptide chains (a polypeptide

ribosomes. The ribosomes are used to make proteins. Nucleus: The nucleus is the place from where all the activities happening in the cell are controlled. All the cell’s information is stored in the nucleus in the form of DNA and chromosomes. Nucleus is the main centre of the cell and that’s why it is also called as town hall. Endoplasmic reticulum: The main job of endoplasmic reticulum is to make proteins. After making proteins‚ endoplasmic reticulum sends these proteins to other parts of the cells.

Prokaryote Organelles: Nucleoid Region: The region in a prokaryotic cell consisting of a concentrated mass of DNA. (The “nucleus” of a prokaryotic cell) The nucleoid instructs all the organelles on what to do. Ribosome: A cell organelle consisting of RNA and protein organized into two subunits and functioning as the site of protein synthesis in the cytoplasm. The ribosomal subunits are constructed in the nucleolus. (Make proteins from amino acids) The nucleoid controls the ribsomes and specifies
