Classical genetics

RETINOBLASTOMA Retinoblastoma is “an embryonal tumor of developing photoreceptors” (Williams), and the majority of cases present in young children age five or younger. It is usually present at birth. Retinoblastoma can also be genetic in some cases. Only 150-350 cases present worldwide each year. It is one of the rarest forms of cancer. I chose to research this cancer because of its rarity. Originally, I wanted to research AML (acute myeloid leukemia), and quickly realized I craved to research…

specific breeding to manually changing DNA, genetic engineering has been controversial to say the least. As genetic engineering continues to grow more ethical issues seem to pop up, especially when dealing with human genetic engineering. There are many different uses for genetic engineering, yet human genetic engineering is to unethical to continue. To fully understand why human genetic engineering shouldn’t be allowed one needs to understand the history of genetic engineering, and how it is…

Genetic Disease: SCD Sickle cell disease is caused by the abnormal change in the haemoglobin gene that slows the flow of blood which causes lack of oxygen to the tissues. Yolanda Smith defines haemoglobin as, “an essential cellular component of the red blood cells that play the role of transporting oxygen in the blood to the bodily tissues where it is required”. ("News-Medical.net", 2015). There are two types of haemoglobin there is HbA that is found in normal red blood cells and HbS one that…

Nikayla Dahl Dr. Albee Cell Biology Section 11 18 September 2016 1. Describe the structure of CFTR. You must provide a written description for full credit. A picture on its own is not enough. A picture with a description is acceptable. (5 points) When cystic fibrosis transmembrane conductance regulator CTFR channels are functioning normally, they allow chloride ions to move outside of the cell. When the CTFR is mutated the chloride ions are unable to leave out of the cell channel which causes a…

When it comes to talking about controversial topics such as politics or religion it is no surprise that people will not see eye to eye on the topic. Therefore, it’s no surprise that gene patenting, the act of patenting genes of DNA to be legally owned by private firms or universities, is also a controversial topic that others, including authors John E. Calfee and Michael Crichton seem to have different opinions on. Crichton, who is against the idea of gene patenting believes the research is…

In this enthralling, enlightening book, Ronald M. Green’s Babes by Design: The Ethics of Genetic Design explores the potential promise and threat in the innovation of genetic engineering. Babies by Design offers several elements of the complicated subject: it presents an eloquent description of the sophisticated technology and science, it clearly recaps the reasonable arguments for and against numerous exercises of biotechnology, and it relates the ideas of science fiction to that of the…

500 girls.” Says Teens Health. Many people today are effected by genetic diseases, “a genetic disease is a disease that is caused by an abnormality in an individual’s DNA.” says Genetic Science Learning Center. A genetic disorder is not inherited but instead caused by a mutations in an individual’s DNA. These diseases shape who people are and affect them and the people around them their whole lives. There are many different genetic diseases, one of these that effect many girls is Turner syndrome…

A Variable Number Tandem Repeat (VNTR) is a molecular motif that plays a considerable role in molecular genetics and specifically forensic analysis [1]. The goal of this experiment is to observe the tandem repeats of the VNTR (D1S80) locus through molecular lab techniques. Cheek cells were isolated from an individual and amplified via a polymerase chain reaction (PCR). Then, the amplified sample was separated through gel electrophoresis. This project entails the interpretation of fluorescing…

variation in other novel genes which have not been studied in model systems. The Variation in seed size is common within and among plant species. Underlying this variation, and thus regulation of seed size, is a complex array of interactions involving genetic factors, developmental signals, and environmental cues. Seed weight is also affected by many biological/developmental processes, including tissue…

instructions that tell information essential to survival. These instructions are in the form of something important to every human: a DNA molecule. DNA is deoxyribonucleic acid. This molecule is present in almost all living beings. DNA transfers genetic information. A DNA molecule is an amazing part of peoples’ bodies. All molecules have a specific structure. What does a DNA molecule look like and how is it designed? Every DNA molecule looks like a curved ladder shape called a double…
