Cell type

mature somatic cell is removed from an organism, and the DNA is transferred to an egg cell whose DNA has been removed. This is commonly referred to as somatic cell nuclear transfer or SCNT. Finally, the egg starts the reproductive process and attaches to the uterus of a female in the same species. This results in a whole organism with the same genetic makeup of the donator of the somatic cell (See Appendix B for a diagram of the process). The last type, therapeutic cloning, occurs when a cell is…

nucleus. To start off, I am going to start with the one in charge of the whole cell or town. The one that is in charge of the cell is the nucleus. In a town it is the mayor or the town hall. There is a reason why I way that is because the mayor makes the laws in the town hall, so basically the mayor is the nucleolus and the town hall is the nucleus.…

to catch its prey with its very sticky tentacles in no time. The toxin is located in the tentacles so they can immobilize their prey. The Aequorea Victoria Jellyfish is virtually transparent and is extremely colorless. What’s so special about this type of jellyfish is that they have a bell…

the cell and other organelles. Fractionation is the process of breaking the cells. Firstly, the tissue is added to a solution which is ice cold, with the same water potential as the cells, and with the same PH as the cells. This has the purpose of preserving the cells so they do not rot. This solution is then homogenized, this is essentially blending the solution so the cells break open. There are four possible procedures for this, high frequency sound waves, a mild detergent, forcing cells…

common type of down syndrome accounts for 95% of the cases. Down syndrome is usually caused by an error in cell division, called “nondisjunction.” Nondisjunction results in an embryo with not two but three copies of chromosome 21. As the embryo develops, the extra chromosome is duplicated in every cell of the baby's body. Mosaicism is the least common form of down syndrome and only accounts for 1% of cases of down syndrome. Mosaicism is diagnosed when there is a mixture of two types of cells,…

which makes it possible to identify genes that gives rise to phenotypic effects when they are switched off, and also helps to analyze the effects of these genes in cells or complete organisms. The first step in the gene trap process is to integrate an artificially constricted DNA into a genome of a cell line, usually an embryonic stem (ES) cell line. To carry out this…

are present in both eukaryotes and prokaryotes, in the cytosol, mitochondria, endoplasmic reticulum and the nucleus. In humans they have a relatively long half-life of about 2 days (Baneyx, F. 2008). HSP70 are a specific type which are normally found in very low amounts within a cell, they can be expressed in response to external stimuli. This external stimuli can be sub lethal heat shock (SLHS) hence the name heat shock proteins (Baneyx, F. 2008), this stimulus causes more of the proteins to be…

’’All biological cells with few exceptions in some follow this rule. This flow takes place through three fundamental processes: replication, transcription and translation. Central Dogma theory was modified when it was found that in some cases RNA carry the genetic information for DNA. The dogma is basically the transfer of sequenced information between information carrying biopolymers. There are three main classes of such biopolymers: DNA, RNA and protein. This transfer is of three types:…

1. a) The three parts of a nucleotide are phosphate, nitrogen-containing base, and the deoxyribose sugar. b) Deoxyribose sugar is the sugar that is found in a nucleotide. c) The nitrogen-containing base is the nucleotide component that contains nitrogen. d) The four nitrogen bases shown in Model 1 are Adenine, Thymine, Guanine, and Cytosine. 2. a) I pointed at a single nucleotide on the ladder model of DNA, on the worksheet. The nucleotide included phosphate, nitrogen-containing base, and…

Human Cloning is the manufacturing of a group of genetically identical cells or organisms, all come from a single individual. The members of a clone have the same characteristics, except where alternation and environmentally caused developmental variation to have occurred. Cloning should be allowed in society because of its significant advantages. Genetic cloning is done to create a necessary gene from DNA to establish certain characteristics. Although this scientific evolution has a lot of…
