Cancer Name Institution’s Affiliations Date Cancer is by itself a disease of cells or disease where the growth of cells is uncontrollable. Most groups of genes causing cancer are: Tumor suppressor genes, they are protective genes by limiting the growth, and as tumor suppressor mutates, cells do grow uncontrollably thus forming a tumor, and examples of such genes are p53, BRCA1. Oncogenes, they change healthy cells into a cancerous cell, such genes are HER2 and the RAS family. Also, the DNA repair genes, these do fix mistakes that are made while DNA is being copied, they include BRCA2. Mutation in cancer includes an acquired mutation in which it occurs during damage to genes in a specific...

Student’s name Professor’s name Course number Date Global Population and Resources. It could be helpful to us as a country and the rest of the world if we could consume fewer global resources. To save on our resources, it is necessary for me and other Americans to adjust our ways of life. To consume less, we should try using other means of transport rather than private vehicles most especially in the busy streets. The methods of transportation include carpooling and using public forms such as buses. The above is an effective way to save on fuel. Also, walking and cycling could be beneficial, not only to save on fuel but also improving our bodies since it is a way of exercising. For...

Different Types of Genetic Disorders -HoloprosencephalyName Institution Different Types of Genetic Disorders -HoloprosencephalyHoloprosencephaly is a structural disorder of the brain which occurs when the brain fails to divide into the left and right hemisphere. Early child development periods.it can affect both the brain and the face. It is a genetic disease that includes continuum malformations of the lobar, middle interhemispheric variant type HPE and semi-lobar. Holoprosencephaly (HPE)is caused by some types of chromosomal abnormalities, and mutation. The risk of the family getting HPE depends on specific causes of HPE in the family. It occurs when HPE is passed in an autosomal dominant mode...

Name Tutor Course Date Ecosystems Western (2001) argued that the current human population can be said to have grown fivefold. Aspects such as soil fertility, and water quality have been degraded severely. The biotic system has also been dissected, depleted and it has also been endangered by increasing human demands. Further, it can be argued that human activities are a significant contributor to global change overriding natural changes to the ecosystems that can be attributed to climate variations. I have chosen to focus on Germany since I have visited their capital city on numerous occassions. This has allowed me a chance to look at the effect of human activities on the ecosystem. Human...

Biology transcription. Titin is the longest known protein which is responsible for the elasticity of muscles. Transcription is a step of gene expression in which a segment of DNA is copied into RNA. Translation is the process of protein synthesis from the information coded in a gene. A promoter is a special sequence that defines where the transcription is going to begin, and the TATA box helps enzyme find the site to bind on the strand (CrashCourse, 2018). Upstream Downstream RNA polymerase works in the 3’ to 5’ direction. Uracil is the mRNA equivalent of thymine. The termination signal stops mRNA from transcribing. 5’ cap and poly-A tail are the enzymes added to the ends of...

Name Course Professor Date Pulse Oximetry Pulse oximetry is regarded as a painless and also noninvasive test in which its sole purpose is able to measure the oxygen saturation level or in other words, the oxygen levels that are currently present in the blood. As such, it is equipped with the ability to be able to detect even the slightest changes in the efficient use of oxygen in far-reaching areas of the body from the heart such as arms and legs. Regarding its area of use, it has been recorded that it is mainly used in emergency rooms or hospitals where there is some level of urgency and critical care being administered. The “first original oximeter was designed and made by Glenn A....
