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.
The fragments are then joined together by DNA ligase, an enzyme that links the 3’ OH of one DNA fragment to the 5’ phosphate of another, forming a phosphodiester linkage. The opposite strand, the leading strand,

The bases used in DNA replication are adenine (A), thymine (T), guanine (G), and cytosine (C). In RNA, uracil (U) is used instead of thymine, but in this case, that is irrelevant. Generally, in a normal human being, A is matched up with T, and G is matched up with C to makeup the complementary base pairs. An important step in the initiation of the replication process is the binding of the RNA primase. This primase attracts the nucleotides that bind to the corresponding nucleotides of the 3’-5’ strand.
stores proteins and alot of exporting (sending stuff out of the cell) 3. In which part of the cell would you expect to find nucleotides? building block for DNA, DNA found in the nucleus 4. Name the two organelles involved in energy conversion.chloroplast and mitochondria 5. What are the basic functions of the organelles in chapter 4?
During transcription, RNA polymerase makes a copy of a gene from the DNA to mRNA as needed. This process is similar in eukaryotes and prokaryotes. One notable difference, however, is that prokaryotic RNA polymerase associates with mRNA-processing enzymes during transcription so that processing can proceed quickly after the start of transcription. The short-lived, unprocessed or partially processed, product is termed pre-mRNA; once completely processed, it is termed mature mRNA. [edit] Eukaryotic pre-mRNA processingMain article: Post-transcriptional modification Processing of mRNA differs greatly among eukaryotes, bacteria, and archea.
These proteins are related to those in the cytoskeleton. The cytoskeleton is responsible for cell movements. They interact and form a coiled coil which in turn produces the nuclear lamina. This part also is the part where chromatin attaches. In the nucleus chromatin is arranged in DNA.
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.
