Nitrogenous Bases Amino Acids
999 wordsDeoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cel...

Carbon Dioxide Amino Acid
1,371 wordsFermentation of glycine, water, sucrose, galactose, and glucose as induced by yeast. ABSTRACT This lab attempted to find the rate at which Carbon dioxide is produced when five different test solutions: glycine, sucrose, galactose, water, and glucose were separately mixed with a yeast solution to produce fermentation, a process cells undergo. Fermentation is a major way by which a living cell can obtain energy. By measuring the carbon dioxide released by the test solutions, it could be determined...

Amino Acids Peptide Bonds
367 wordsA gastric gland is a tubular structure in the vertebrate stomach that secretes gastric juices. The gastric glands have three types of cells that secrete different components of the gastric juice. One of them is being a chief cell, which is a rust color and is an inactive form of the digestive enzyme Pepsin. Pepsin begins the digestion of proteins in food. Pepsin is a Peptidases, which is an enzyme that breaks peptide bonds of proteins. Pepsin is found in the mucosal lining of the stomach that br...

Gram Positive And Negative Bacteria
828 wordsGram Positive and Gram Negative Bacteria It is a well-known fact that bacterial cells, like plant cells, are surrounded by a cell wall. However, few people know that their cell walls are quite different. Bacterial cell walls are made up of polysaccharide chains linked to amino acids. At the same time, plant cell walls are made up of cellulose, which contains no amino acids. In the same way, bacterial cell walls themselves differ from one another. Scientists distinguish two types of bacteria cell...

Gel Electrophoresis Carbon Dioxide
2,361 wordsPyruvate Decarboxylase There are two functions of the pyruvate decarboxylase. Pyruvate and hydroxythyl converge together while carbon dioxide molecules are eliminated. Than, hydroxy ethyl group transfers and attaches to TPP to the lipo amide from the E 2 component of the complex. The final transfer brings the molecule back to its original form. (Function) The molecular weight of the enzyme was found to be 240, 000 by polyacrylamide gel electrophoresis (Oba). There are 548 amino acids and very si...

Some of these enzymes break down proteins, others attack fats, and still others disassemble the nucleic acids that make up DNA and RNA (Bourne, 1992, p. 123). Lynosomes don't always work right. When they fail, the result can be catastrophic disease. In Tay-Sachs disease, for example, victims have inherited a faulty gene, which leads to a defective enzyme or no enzyme at all. As a result certain undigested molecules accumulate in the lysosomes, gradually lead...

These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the building blocks of life. These monomers combine to make polymers, which is a long chain of monomers strung together.

807 wordsToday, weve realised that the very first life on Earth was indeed originated from abiotic surroundings. In fact, organic molecules have been successfully generated from abiotic elements by scientists To understand how this creation of life from abiotic material occured, we have to consider a critical idea. Life originated from its abiotic surroundings. Thus, it is important for us to learn about the physical and chemical environments of the primitive Earth. The atmosphere of primitive Earth cons...

Protein Synthesis Amino Acids
788 wordsProtein synthesis is one of the most fundamental biological processes. To start off, a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described, a person must know what proteins are made out of. There are four basic levels of protein organization. The first is primary structure, followed by secondary structure, then tertiary structure, and the last level is quaternary structure. Once someone unders...

Amino Acids Dna Molecule
245 wordsProtein Synthesis Protein synthesis is the process by which genetic information from the DNA stored in the nucleus is transferred to the ribosomes where it is used to arrange amino acids into proteins. The DNA molecule in the nucleus is unzipped by an enzyme called polymerase. From one of these single strands of a DNA molecule, a mRNA molecule is built. This is accomplished by an enzyme which travels along a portion of DNA between two exons and attaches the opposing base pairs to the backbone of...
