Double Helix Essay

With the advancement of medicine and improvement in the quality of life is leading to an increase in the group of older people in our society. The majority of the elder people around 60 to 70 % are independent, 30% are classified as fragile or at risk, and only 3% are adults greater bedridden or disabled. As we exceed 65 there is an increase in the probability that functionality of humans will start showing its limitation. Before discussing the characteristics of the aging process, and the main…

Extra-Terrestrial: What are Humans? Every 80’s and 90’s kids remember their favorite childhood blockbuster E.T, the Extra-Terrestrial. The story of an alien who was abandoned in California and had to experience the curiosity, love, compassion, friendship as well as the aggressive, threatening, and horrible aspects of humankind. This 1982 Universal Pictures film is a science fiction movie, but does it have to be science fiction? Could there be a day that we, the human species, find and…

The word hero can have multiple interpretations depending on whom is asked: an inspirational teacher, a great leader, or long dead philosophers. By definition, a hero is someone, through their achievements, is seen as a role model or someone who would be looked up to and admired. Although, heroes are anything but by the book, so extraordinary, that using a written definition only boxes in these incredible people. A few traits that many heroes possess are generosity, being adventurous and…

Transcription is a process which information from DNA is converted into its RNA equivalent which also refers to the synthesis of RNA copy of information encoded on DNA. The same principles of transcriptional regulation apply to both eukaryotes and prokaryotes. Transcription involves in access of transcription apparatus to DNA, recognition of promoter sequences, initiation of RNA synthesis, elongation of RNA, and termination. Transcriptional in eukaryotes is more complex compared to prokaryotes…

Could the World be filled with “Superhumans”? Upon hearing the word “superhuman” my mind immediately conjures up a being with inhuman like qualities and superpowers- typically, I imagine the comic book mutants from X-Men. With modern technology and advancements in genetics, the idea of a superhuman is becoming more and more plausible, although do not expect to see Magneto causing chaos in the street anytime soon. A superhuman can be defined as a human with heightened intelligence and physical…

Alongside CRISPR-Cas9 in site specific genome editing are ZFNs and TALENs. ZFNs are a DNA-binding motif assembled as ββα that utilizes a roughly thirty amino acid protein with DNA recognizing amino acids at the alpha helix (Gaj, Gersbach, & Barbas, 2013). These groups of amino acids usually recognize DNA in segments of three. This does not present much specificity in a genome. Therefore multiple DNA-binding motifs need to be combined to create specificity and result in highly specific…

This involved the work of two scientists, James Watson and Francis Crick. They used the x-ray data provided by Rosalind Franklin which helped them to make an accurate model of the DNA. The model presented the structure of DNA showing a double helix with little rungs connecting the two strands and identified that the rungs were the bases of nucleotide. The structures they identified have had minor changes implying that they were a bit perfect despite the challenges faced while bonding the…

In virtually every language, the term for Abirthmark@ can be translated as some variant of the terms Aenvy,@ Awish,@ Alonging,@ or “mother’s mark.” Does this suggest anything to you about what people in the past thought might be the causes of birthmarks? something the mother did caused the birth mark? D. Birth Process 14. Childbirth is conventionally divided into three stages. What are they?  mother experiences regular uterine contractions that are usually spaced to 10 to 15 minute…
