MEDICAL USES Diagnostic Biotechnology Uses Biotechnology plays a vital part in the diagnostic science‚ as it uses our knowledge of both DNA and genes to help determine the following. Determine the sex of an unborn baby Prenatal Screening‚ such as screening for Down syndrome. New-born Screening‚ used to pick up diseases such as HIV Presymptomatic testing for adult onset disorders‚ this includes testing for familial high blood cholesterol.

Chapter 6 Explain what free energy is and how it can be used to predict the energetic outcome of chemical reactions.Free energy is defined as the energy available to do work in any system. The free energy is denoted by the symbol G. G = H – TS* H: the energy contained in a molecule’s chemical bonds‚ called enthalpy.* TS: the energy term related to the degree of disorder in the system. T is the absolute temperature (K)‚ and S is the entropy.We can use the change in free energy to predict whether

say that the Human Genome Project is probably more significant than splitting the atom or going to the moon." (Francis Collins) The human genome project‚ started in 1988‚ has mapped all the genes in the human body and sequenced them. Researchers are now working on understanding the function of all the genes. This exciting new development in biology has opened up whole new areas in the genetic world. The Human Genome Project was an enormous accomplishment in the field of biology; however‚ there are

the ribosome reaches a stop codon and an amino acid sequence‚ or a protein‚ is made. To find the original traits‚ I found six start codons (TAC) and six stop codons that did not overlap with other codons. I then labeled each gene from A through F and transcribed the genes to mRNA. Once transcribed‚ I translated mRNA to an amino acid chain forming from what each of the codons coded for. Then‚ using the sheet with the traits with corresponding amino acid chains‚ I found the original traits. The original

What determines how a child develops? In reality‚ it would be impossible to account for each and every influence that ultimately determines who a child becomes. What we can look at are some of the most apparent influences such as genetics‚ parenting‚ experiences‚ friends‚ family relationships and school to help us understand the influences that help contribute to a child’s growth. Think of these influences as building blocks. While most people tend to have the same basic building blocks‚ these

Gene pool: the total aggregate of genes in a population at any one time. It consists of all alleles at all gene loci in all individuals of the population 3. What is the Hardy-Weinberg Theorem and why does it appear to be an apparent contradiction to evolution? The theorem states that frequencies of alleles

The cause of albinism is a mutation in one of several genes. Each gene provides the chemical code instruction for making one of the several proteins involved in the production of melanin. Melanin is what makes the color of the skin its color and also your eyes and hair. You must inherit two copies of a mutated gene in order to have albinism. Albinism is not always apparent in a person’s skin‚ hair‚ or eye color. All albinism victims will experience vision impairments. You may have rapid‚ involuntary

What is a gene? A gene is a continuous DNA segment that is transcribed into a single preRNA molecule. A zoologist and geneticist named Thomas Hunt Morgan is known for his research with fruit fly. Thomas Morgan was born on September 15‚1866 in Lexington‚ Kentucky. In 1886‚ he received his B.S. degree at the University of Kentucky. In 1910‚ Morgan saw that one male fly had a distinct difference about it. Instead of normal red eyes‚ this fly had white eyes (Allen). He wanted to test the breeding of

myasthenic syndromes is genetics‚ affecting the junction where the nerve triggers muscle activity. The inherited autosomal recessive gene exists in both parents‚ who pass the mutated gene to the offspring. The syndrome appears shortly after birth or early childhood. Severity ranges from minor to increasing concentrations of muscle weakness. There are over twenty different genes known to cause congenital myasthenic syndromes‚ as different as each individual. Sometimes the conditions occurs randomly without
