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

Disease is a homozygous dominant neurodegenerative disorder caused by a mutation in the HD gene. The mutation involves the basal ganglia‚ striatum and cerebral cortex parts of the brain and causes a CAG trinucleotide repetition. This repetition then proceeds to cause involuntary chorea‚ mood disorders‚ mental instability‚ and eventually leads to death. Since this is a relatively new discovery the Huntingtin gene is still mysterious in many ways to researchers. Many new discoveries have been made in

Chapter 13: Meiosis and Sexual Life Cycles 1) Genes are the units of heredity‚ and are made up of segments of DNA. 2) In asexual reproduction‚ one parent produces genetically identical offspring my mitosis. In sexual reproduction‚ two parents give rise to offspring that have unique combinations of genes inherited from the two parents. 3) Humans have somatic cells‚ which are any cell other than a gamete‚ have 23 pairs of chromosomes. A karyotype is an ordered display of the paired of chromosomes

born with a set of genes that never change. When we are conceived‚ two sets of genes are joined into one. From that moment‚ DNA determines certain characteristics. We can now readily accept that genes determine our eye color‚ height‚ blood type‚ gender and other biological factors. But science has only begun to explore the role that genes play in human behavior. Some People believe that the power of genes‚ determines all consequence in our lives. But other people say that genes do not determine
