Although homologous chromosomes contain the same genes‚ they can have different alleles of the same gene. An allele refers to one of plenty of alternative forms of the same gene. For example‚ a set of homologous chromosomes explain eye color. One of the chromosomes genes explains blue eyes‚ and the other one explains brown eyes. This is the

The study of genes‚ Genetics‚ is a branch in Medicine that studies how genes are formed‚ distributed and how they change the organisms’ characteristics. The pioneer in the field of Genetics‚ Mendel‚ was able to formulate various laws based on genes‚ such as the law of segregation. Even though Mendel did not know about the existence of DNA‚ he was able to show that some traits are carried to offspring‚ even though the parents did not appear to have the gene. There are two types of genes‚ the dominant

The four forces of evolution include mutation‚ gene flow‚ genetic drift‚ and natural selection. Mutation is when there is a change occurs in a gene or chromosome structure which results in a difference in a physical or behavior trait. This trait can be carried into the next generation because the trait is contained in the gene. Gene flow is the process of genes transferring from one population to another. Genes can be transferred to different populations by migration of individuals along with the

wanted to be able to get something out of it. I did not want it to be a long‚ boring‚ and uneventful lecture. But to my surprise it was not! To quickly sum up which lecture I went to‚ it was in Smith Hall by Dr. James Peterson talking about “Human Gene Editing Now: The National Academy of Science’s Pursuit of What We Should Do.” Dr. James Peterson first began to talk about nature and how God admired nature. He asked us if our we had a garden would be not improve and restore it. Dr. James Peterson

Study for Bio 97 Notes for Finals (ADL HW 10) Item #1 Recombination occurs when combinations of alleles not found in either parent are placed into gametes during meiosis in the F generation. The F can be thought of as having been formed 1 1 from two haploid “input” gametes. In this case‚ the F is a dihybrid with AB on one chromosome and ab on the other 1 chromosome

This article and video about CRISPR ‚ a technology that would allow for gene editing. CRISPR uses a bacteria and enzyme to target a gene and edit it in hopes to cure genetic diseases. The DNA is extremely complex and changing genes can have an unintended consequence. This important as ethics plays a big role in the support or oppositions of gene editing. The video shows how CRISPR works visually. Now that DNA can be changed and made to be inherited with nearly 100 percent success‚ debates on if

LB (Luria Broth) plates with ampicillin and determining if any genetic transformation has occurred. By combining +pGLO LB and ampicillin we should get an ampicillin resistant gene and by using –pGLO we should create a non-genetic resistant bacteria. The pGLO plasmid has the GFP (green fluorescent protein) gene and the gene that allows the plasmid to be resistant to the antibiotic ampicillin. The most important part of this experiment is the “heat shock treatment” because the E. coli membrane becomes

This gene makes a protein‚ called (pRb)‚ that helps stop certain cells from growing too quickly. In about 1 out of 3 children with retinoblastoma‚ the abnormality in the RB1 gene is present at the child’s birth and is in all the cells‚ including the retinas of the eyes. This is known as a germline mutation. Children born with a mutation in the RB1 gene usually develop retinoblastoma in both eyes‚ known as bilateral retinoblastoma

match characteristics among unrelated creatures by moving genes from one creature to another. This is called “genetic engineering.” Genetic Engineering is a test tube science and is prematurely applied in food production. There are estimates that food output must increase by 60 percent over the next 25 years to keep up with demand. Thus‚ the result of scientist genetically altering plants for more consumption. The two most common methods for gene transfer are biological and electromechanical. “Early
