Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

The external environment’s effects upon genes can influence disease‚ and some of these effects can be inherited in humans. Studies investigating how environmental factors impact the genetics of an individual’s offspring are difficult to design. However‚ in certain parts of the world in which social systems are highly centralized‚ environmental information that might have influenced families can be obtained. For example‚ Swedish scientists recently conducted investigations examining whether nutrition

Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine

How do we know we know what each individual gene does? One way to investigate the function of a gene is to just remove the gene and analyze what happens to the organism. Let’s say we have a gene of unknown function in the human genome‚ an unidentified gene. First‚ compare it to other genes to see what similar sequences they have‚ if they code some similar sequences they might code for similar functions. However‚ if the gene the unidentified gene codes for something different we have seen before this

genetic conditions. The current on-going research is in the field of gene therapy‚ an experimental technique that uses genes to treat and replace the defective genes of an affected person. Instead of treating disease symptoms‚ this has the potential to correct the underlying cause (1). Besides its high costs and ethical concerns (therapy involving germ line treatment)‚ this technique also poses a considerable amount of risk. Thus‚ gene therapy is currently only being tested on the diseases for which

a fault in the cystic fibrosis transmembrane conductance regulator (CFTR) gene on chromosome 7 at q31.2. For CF to be expressed‚ a faulty copy of the gene must be present at both alleles; autosomal recessive. Therefore both parents must be carriers of‚ or affected by the cystic fibrosis gene (fig. 1) for the gene to be passed on. If a person has one copy of the faulty allele (are heterozygous) they are carriers of the gene and can pass this allele on; if they possess two copies of the faulty allele

everyday‚ a new controversial topic appears. Most recently‚ the controversial topic is human germline gene therapy and this type of therapy does not have a place in 2016. I am against germline gene therapy because it is too early for human research‚ we as the science community do not know enough about the process of how genes control phenotypic expression‚ and if the technology to edit germline cells would be leaked to the public it could create an entirely new social inequality.

Gene therapy was introduced into the scientific field around 1972‚ which led to the first attempt at its use in 1980. Although original efforts were unsuccessful‚ this event ignited research into the idea‚ which has led to the multiple developments in gene therapy still being refined today. Around the same time‚ biotechnology also emerged as a new and ingenious tool in field of biology which only furthered the potential abilities of gene therapy. Current research surrounding these fields combines
