Sun is the essential part of our life. It helps regulate the climate and it is the main source of energy in the ecosystems. If just one of these factors changed markedly, it would impact all life on Earth. Furthermore, sunlight also helps our bodies to form vitamin D underneath the skin. This vitamin helps people to build and maintain bones. However, beside all of it’s good qualities, the sun can also be harmful in large amounts. One of the most dangerous factors from sun is exposure of UV…

Amino acids Amino acids are building block s of proteins. Each amino acid contains main three structural components. 1) Amino group 2) Carboxcilic group 3) R group Figure 1 https://www.bing.com/images/search?q=amino+acids&view=detailv2&&id=072990A13D7C6B29926E0FC3F9E9BE59C8A6322E 2016 R can be hydrogen or any other functional group .in world there are around 182-200 found to be present in nature but we can find 20 aminoacids in…

Introduction DNA is called deoxyribonucleic acid. This contains a phosphate group, sugars, and a complementary base. DNA is found in plants and animal cells in the nucleus. The nucleus is the control center where DNA is replicated or produced within a cell. DNA also contains our genetic material. This is possible due to differences in individual’s phenotype and genotype. DNAs structure is double helical; meaning two strands are parallel to each other and in a ladder formation. This can occur…

and X-ray crystallography. They took especial interest in earlier genetic study. Early genetic research included that of Biochemist Erwin Chargaff, who had composed Chargaff’s rules. His rules stated that among DNA’s four bases adenine (A) and thymine (T) always appeared in ratios of one-to-one as did guanine (G) and cytosine (C). Two other researchers, Maurice Wilkins and Rosalind Franklin, had gotten X-ray images of DNA that suggested a helical, spiral shape (“The Francis Crick Papers,” 2013)…

Unit 2 Project In your own words Discuss why carbon is essential to life on Earth. (150 word minimum response) Carbon is a vital element in organic compounds. Organic compounds are compounds that are usually located in living things.Organic compounds are very vital and Carbon is an elemnt that makes up organic compounds. Carbon helps organic compounds make up cells and carry out important life functions.Additionally, carbon can form strong bonds with itself and many other elements. This…

A. RNA doesn’t have thymine. RNA uses Uracil. RNA can leave the nucleus. B. mRNA- mRNA is called the messenger DNA. This RNA can leave the nucleus and delivers information to other parts of the cell. tRNA- Transfers amino acids to proteins. Ribosomal RNA- Forms parts of ribosomal subunits C. Proteins must be synthesised constantly in order to use the codes from genes over and over again. 2. A. During transcription, the enzyme RNA polymerase binds to DNA and separates the DNA strands. It then…

A. Eukaryotic cells store their genetic information in chromosomes made of DNA. This DNA is copied during interphase of the cell cycle. Replication is semiconservative, meaning one strand of the replicated DNA would be from the original molecule and one would be new. The parental strands serve as templates for the new strands. Replication can begin when helicase breaks the hydrogen bonds responsible for holding the two complementary strands together, ultimately causing the molecule to unwind…

It’s important to realize that each scientific break through is made possible by the work that came before it. It’s a lot like putting puzzle pieces together, collecting different important evidence until enough puzzle pieces result in another break through. Fifty years ago two scientists announced to a lunch time crowd that they had discovered the secret to life. How DNA changed the world To begin with scientists used to have no understanding of what caused distinct patterns of inheritance.…

of our discovery, was the UV mutations in the bacterial genome. UV light is an extremely high-energy particle, and extended exposure to concentrated amounts of this light can cause an error in base pair reading by RNA polymerase due to thymine dimers. These thymine dimers cause the normally linear reading polymerase to perceive the DNA as a bubble; either passing it entirely, or just coding the complementary strand incorrectly. The longer the exposure to UV light, the more inconsistencies in the…

How does the gene code works to control variation within a species: Genes control variation by coding for certain traits inside an organism. Those codes are adenine, cytosine, guanine and thymine. All of these four codes are acids and these acids depends on the variation within a species. This is how it makes an organism change the way it look physically. The four simple coded message codes for everything like eye color to height. Genes codes for many traits and they are important in…
