This protein causes the jellyfish to glow in the dark. With gene transformation the bacteria will acquire this trait and they wil glow underneath an ultraviolet light. Bacteria contain a large singular chromosome and one or more smaller circular pieces of DNA called plasmids. these plasmids usually contain one or more genes that are beneficial to the survival of the bacteria. in nature, the bacteria can transfer these plasmids from bacteria to bacteria, transfering those beneficial genes.
Kirstie Javier AP Biology Period 4 November 14, 2011 Proteins Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. Some types of chemical bonds/ interactions are disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions. Disulfide bonds form when two cytosine molecules join together to form a bond between their two sulfur atoms. Such bonds cross-link polypeptide chains or parts of chains. Because they are nonpolar covalent bonds, they are very strong bonds and not easily broken.
Chromatography Lab Title: Paper Chromotography of Photosynthetic Pigments Lab Purpose: The purpose of this lab is to determine the characteristics Rf of each of the four pigments (Carotene, Xanthophyll, Chlorophyll a, and Chlorophyll b). Materials: see attached lab sheet. Procedure: see attached lab sheet. Research Information: Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate.
The length of the Great Barrier Reef is 1,553 miles long. An abiotic component is a non-living organism that is physical rather than biological. A biotic component has life or living organisms. Hermatypie corals are types of abiotic components that help the coral in the Great Barrier Reef. This refers to the very colorful Zooxanthellae algae.
The Importance of Shapes Fitting Together in Cells and Organisms Lots of molecules in cells and organisms fit together with other molecules that have complimentary shapes in order to work and serve their purpose. An example of a type of molecule that does this is enzymes. Enzymes are proteins that speed up metabolic reactions, from the digestion of food to the synthesis of DNA, and so are very important. One of two models that demonstrate how enzymes work is the ‘lock and key’ model, in which the active site of an enzyme has a complimentary shape to a specific substrate and they fit together perfectly (like a key in a lock, hence the name) to form an enzyme-substrate complex. The other model is the ‘induced fit’ model, which describes the formation of an enzyme-substrate complex as a result of the enzyme’s active site adapting its shape to fit with the substrate (almost like a glove) to allow for
And it also has many other important roles in cells like controlling the cell cycle and cell growth, signaling, cellular differentiation and cell death. The mitochondrion is different from other organelles in the cell. It does carry its own circular DNA. They are able self-replicate. It is also free of a nuclear envelope, and the DNA is not packed into chromatin.
Cresyl violet and several other dyes are able to bond with structures within the neuron cell bodies allowing researchers to count or estimate the number of cell bodies within a region. Both of these neuroanatomical techniques have positive features however, each lacks in some respect. The Golgi stain was the first time that researchers were able to study individual neurons in detail. It can be used to detect and study the shape of neurons as the silver chromate perfectly fills the neuron so that a detailed black silhouette becomes visible. This allows not only the structure of the neuron to be examined, like the axon and the dendrites, but also any abnormalities to be studied.
LAB REPORT 1 Finding PROTEINemo Introduction In the vast ocean of proteins one will try to locate an unknown protein amount. Proteins are long chains of amino acids, and critical to the building of various tissues in the body such as muscle, hair, enzymes and antibodies. Proteins have other various important functions in rebuilding and building of the human body. In order to find what a protein is, one needs to looking at peptide bonds. The most effective way to find peptide bonds, which join amino acids to form a protein, is by using Biuret reagent.
It does this by controlling the enzymes present. The chromatin is composed of DNA. DNA contains the information for the production of proteins. | Mitochondria | Mitochondria have two membranes (not one as in other organelles). The outer membrane covers the organelle and contains it.
They are a source of food and medicine, and they protect the coast from wave erosion. Profile of coral reef with typical reef "zones" Corals are marine animals related to jellyfish and anemones. Both colonial and solitary corals catch plankton (microscopic plants and animals) and other suspended food particles with arm-like tentacles, which feed a centrally located mouth. Most hard corals also host symbiotic algae, a long-standing and successful partnership. These algae provide them with an additional food source through photosynthesis.
