F. The plasma membrane controls the movement of substances in and out of the cell. G. The role of the Smooth Endoplasmic Reticulum is to detoxify the organ or cell. H. Chromatin (DNA) is formed when hereditary material and protein combine. They then condense and from chromosomes for cell division. I.
Proteins are formed through condensation reactions which bond amino acids together with peptide bonds in a particular sequence and the type of protein that is created is defined by the unique sequence of the amino acids. DNA and RNA are nucleic acids that are formed in the nucleotides and are both involved in the process of protein synthesis. Deoxyribonucleic acid, more commonly known as DNA, is located within the nucleus of the cell and contains the entire genetic code for an organism within its structure. DNA has two very important functions which are: to convey information from one generation of cells to the next by the process of DNA replication and to provide the information for the synthesis of proteins necessary for cellular function. Basically, DNA controls protein synthesis.
Rough ER transports these proteins to the regions in the cell where it is needed. | Ribosomes | A ribosome is composed of two parts known as the large and small subunits. Each of these is a combination of protein and a type of RNA known as rRNA. | the main thing they do is that they arrange the strands of the amino acids for use of the other parts of the cell and ultimately the body. | Goigi Apparatus | The main function of the Golgi apparatus is to be responsible for handling the macromolecules that are required for proper cell functioning | It packages and ships molecules made in the ER.
Transgenesis and Cloning Transgenesis is the process of inserting a gene from one source into a living organism that would not normally contain the inserted gene. The gene can come from the same species (called Cisgenesis) or from a different species entirely. To facilitate the transfer of genes from one organism to another, often a Transgenic Organism with Recombinant DNA is created: -The first step in creating an organism capable of carrying out the transformation process is to isolate the required gene. This is done so using Restriction Enzymes, which target a specific gene sequence. The gene is often cut with staggered ends, called “Sticky Ends” which only allow specific and complementary gene sequences bond by base pairing.
Nucleus 11. Nuclear Envelope Step 2: Write a description of the above organelles: Nucleolus – a non-membrane bound structure found in the nucleus. The nucleolus transcribes rRNA and combines it with protein to form almost-complete ribosomes. Smooth Endoplasmic Reticulum - Smooth ER synthesizes fatty acids and steroids, inactivates or detoxifies drugs and other potentially harmful substances, removes the phosphate group from glucose-6-phosphate, and stores and releases calcium ions. Lysosome - Membrane-enclosed vesicles that form from the Golgi complex that digest substances that enter a cell via endocytosis and transport final products of digestion into cytosol.
Death Cap Mushroom Transcription and Translation: mRNA is necessary to direct synthesis (transcription) of the polypeptides. In other words to copy the DNA. The information on DNA is coded into mRNA here. Information is rewritten and translated into a protein. The death cap mushroom toxicity can cause inhibition of RNA Polymerase II, the enzyme necessary for synthesis of mRNA.
The first step of DNA replication is the unwinding of the two individual strands of DNA that are together in a structure that is known as a “double helix”, a term coined by Watson and Crick, who founded the first original model of DNA. The enzyme that is used to split the two strands is called helicase, and the splitting process starts in a place called the “origin of replication”. After each separate DNA strand has successfully unwound, the bases that are present on the strands are now exposed, and unpaired. The enzymes then match the bases with the free nucleotide triphosphates. The bases used in DNA replication are adenine (A), thymine (T), guanine (G), and cytosine (C).
“Introduction” Boundless Biology). The Cytoplasm is the material between the cell membrane and the nucleus. It has a lot of responsibilities within the cell. It contains enzymes for breaking down waste and also gives the cell its shape. The Nucleus or the brain which it is sometimes called is covered by a double membrane.
Each genome contains the information needed to maintain and create the organism. The process of genetic engineering involves extracting of a small piece of cellular DNA, called a plasmid, from the bacteria if organism involved in the manipulation. A very small section of the circular plasmid is then cut out by the restriction enzymes which act as molecular scissors. The gene from the organism being modified is then inserted into this space and the plasmid is therefore modified. The genetically modified plasmid is now inserted and introduces into a new organism which starts divides rapidly.
The Nuclear Envelope is made up of two layers, each is made of lipids. It is a membrane that covers the nucleus in the eukaryote cell. These cells generally have nuclei in which the genetic material is separated from the rest of the cell. The envelope separates the contents in the nucleus from the cytoplasm which contains the organelles. The nuclear envelope is marked with tiny holes called the complex nuclear pores; these keep the moving in and out of things like RNA and proteins between the cytoplasm and the nucleus running smoothly.
