Genetic diversity

In the Achieve 3000 article “China and Japan: Can Animals Sense Trouble?” talks about the argument of whether nature and animals can or cannot predict and warn us of when a disaster is about to happen. This article provides reliable evidence for both sides of the topic that will help you decide which side you will be on. Evidence that is for animals can predict is from this article is a quote by seismologist Roger Musson: “there are several possible reasons for behavioral changes in animals…

Rad8 is a conserved protein, it was previously reported to be sensitive towards both UV and gamma irradiation during G1/S period in Schizosaccharomyces pombe (Doe et al., 1993). It consists of three conserved domains, including E3 ubiquitin ligase motif, SNF2 helicase domain, and a family specific HIRAN domain. Rad8 is required for error-free post-replication repair by contributing to polyubiquitylation of proliferating cell nuclear antigen (PCNA). Up-regulation (12.52-fold) of Rad8 indicated…

Having freckles is a common and harmless condition that is shared among many people around the world. Freckles are passed down genetically, and are a dominant trait. They are most common and most easily seen on fair skinned people. Many people with freckles notice that their freckles become darker after being out in the sun. This is because freckles are basically clumps of melanocytes, and the sun's ultraviolet rays cause melanocytes to create more melanin, making the freckles darker. Now,…

As for children that suffered the hearing loss at birth will have a harder time with comprehension and speech because of the temporal lobes auditory areas taking over the other functions of other senses. With them being no more than different from a hearing person because they do still bleed the same color blood as us. We can get around to what has actually happened to the development of the ear and what caused the auditory cortex to be shot. The diseases stated above such as Cytomegalovirus…

What is reality? Is there a connection to your brain and the world around you? Is it really what you think it is? Current knowledge about our bodies state that the brain sees the world by using millions of stimuli around us to perceive the feelings of cold, soft, bright, and countless others. Take a look at this sunset, you see the sunset in front of you but when you leave the area. Was there really a sunset at the time period. Your mind says yes since you recall being there but is there…

X chromosome rather than two. As the baby grows and the cells divide, the X chromosome will be missing from every cell of the baby's body. In some cases, both X chromosomes are present, but one is abnormal. It may be shaped differently or missing genetic material. The effects of the condition vary widely among girls with Turner syndrome. It all depends on how many of the body’s cells are affected by the changes to the X chromosome. The abnormality is not inherited from an affected parent (not…

It can be argued that “… the origin of life is the origin of replication” (Lane, 2010). This statement proves to be correct to a certain extent as if there were to be any mutations within the stages of replication, the life created could have abnormalities which may decrease quality of life experienced. Sickle cell anaemia is a hereditary form of anaemia in which a point mutation causes the formation of haemoglobin which distorts the erythrocytes into a sickle-shape (Appendix 1). The sickle…

“Genome editing” is a form of genetic engineering that involves the addition, deletion, and modification of genes in a genome. The genome of an organism is the full genetic complement of that given organism hence by editing the genome, scientists are able to alter the phenotype of these organisms and can modify the cellular functions occurring within the organism. Mutations in the DNA of an organism occur during DNA replication. For example in the human genome, it is thought that there are 6…

associated with other diseases such as pulmonic stenosis and tetralogy of Fallot. “In more than 90 percent of cases, mutations in the JAG1 gene cause Alagille syndrome. Another 7 percent of individuals with Alagille syndrome have small deletions of genetic material on chromosome 20 that include the JAG1 gene. A few people with Alagille…

Each gene has instructions to make or build a protein. In protein coding the sequence is always in groups of three nucleotides. These groups of three are called codons. Every codon has one amino acid in a protein. All proteins need to start with the ATG codon. Most biological activities are carried out by proteins. In order to have the DNA sequence that reads ATG-ACT-CAT-GAG-TGA to be translated into the RNA to build a protein there has to be proteins that are not the same to be able to…
