What is the fallacy behind taking amino acid supplements? 6. Describe the process of cellular protein synthesis (transcription and translation). Include the role of DNA, mRNA, tRNA, and ribosome. 7.
What is genetic engineering Genetic engineering: The manipulation of an organism’s genes. Genetic engineering is a method of combining techniques of genetics and biotechnology used to separate and join genetic material, DNA, from one or multiple species of organism and to introduce the result into an organism to change one or more of its characteristics. Recombinant DNA technology: The technology used in which a series of procedures are used to recombine DNA segments. A recombinant DNA molecule is produced from segments of two or more different organism’s DNA. Under the correct conditions, a recombinant DNA molecule can move into and replicate in a cell, either by means of integration into a chromosome or by its self.
What are other names for the acetyl co-A formation stage? 3. Why are mitochondria often called the “powerhouses” of the cell? 4. Where in the cell does acetyl co-A formation occur?
* An electrogenic pump is a transport protein that generates voltage across a membrane * Animal- sodium/potassium * Plants- proton pump Understand how a co-transporter works. Where you likely find one? Understand how large molecules and particles are transported across membranes including the role of Vesicles. What is meant by endocytosis? There are several types – what are they and how do they differ?
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.
-After the gene is amplified a suitable vector is selected for use. A vector is a self-replicating DNA molecule used to transmit a gene from one organism to another. All vectors must contain the following characteristics: 1. Able to replicate host organism. 2.
