Describe The Factors That Contribute To The Process Of Ageing
Ageing is the process in which humans and bodies of organisms physically get old, and its causes can be environmental and/or genetic. As a person gets older, they tend to develop and maintain some habits that can affect their health either positively or negatively, and this represents the accumulation of changes in a person over time. There are several factors that can contribute to the process of ageing; there are also ways to slow it down. How and why ageing occurs are all under the guideline of DNA.
DNA (deoxyribonucleic acid) is a complex molecule which consists of two strands coiled together to form a double helix. Nucleotides serve as the monomers of each two of the DNA strands. These nucleotides are composed of either one of the chemical bases: (A) adenine, (T) thymine, (C) …show more content…
Complementary-base pairing is a rule that A always pairs with T and C always pairs with G, this keeps the two strands tightly wound together by hydrogen bonds. DNA carries the genetic information of a living organism which determines its characteristics and contains instructions for development and growth. The bases of the DNA hold different codes that are required for different amino acids. A section of DNA is called a gene and the sequence of bases determines the sequence of amino acids in a protein molecule. The central dogma of life explicates the flow of genetic information from DNA to RNA, which then codes for the protein [DNA (transcription-process of making messenger RNA) > RNA (translation-process of transforming the mRNA sequence to a sequence of amino acids) > protein]. DNA is organized into chromosomes which are found in the nucleus of cells. A significant function of DNA is

    Deoxyribose Nucleic Acid (DNA) is a polynucleotide molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Most DNA molecules are double stranded helices, consisting of two polynucleotide strands made up of simpler molecules known as nucleotides. A nucleotide is made up of an organic nitrogenous base, a deoxyribose sugar and phosphate groups. It is order of these bases which make up the genetic code; a set of rules, by which information is encoded within genetic material.…

    DNA is typically has two strands running in opposite direction and is usually referred to as a double helix. Each on the individual strands consists of a backbone that is formed by sugar molecules linked together in groups. Each individual sugar molecule is covalently linked to one of the following possible bases: Adenine, Guanine, Cytosine and Thymine. These bases are typically aligned perpendicular to the axis of the strand. As previously stated the strands run in opposite directions with the bases paired up with Adenine always with Thymine and Guanine always with Cytosine. Theses pairs form hydrogen bonds with the A/T pair having 2 and the G/C pair having 3. The extra hydrogen bond makes the G/C pair stronger.…

    Describe the structure of DNA.DNA is thread formed by two strands, related together to form a double helix. The double helix looks like a twisted ladder. The sides of this ladder are long unites called nucleotides and are made of three parts; a nitrogenous base, a sugar, and a phosphate group. The sides of the ladder or the nucleotides from the two separate strands of the DNA are attached by an appendage made of one of four separate bases. These appendages represent the rungs of the DNA ladder and are attached to the complimentary strand of the DNA. The bases or rungs are made of either Adenine (A) OR Thymine (T) or Cytosine (C) and Guanine (G). The attachment of the strands by the bases is specific Adenine can only join with Thymine, and Cytosine can only join with Guanine. Since this base pairing is specific, if one knows the sequence of bases a long one strand of the DNA one will also know the strand of the DNA one will also know the sequence along the complimentary strand.…

    DNA is a structure of specific molecules and a complex mixture of chemicals. DNA is a nucleic acid, which is a group of complex compounds that can be found in all living cells or viruses, and controls cell health and function. Nucleic acids are composed of polymers and monomers, which are referred to as nucleotides. There are four different types of nucleotides that make up the structure of DNA, which are abbreviated A, C, T, and G. Covalent bonds join together nucleotides through sugar and phosphate. Polynucleotides, or a polymer nucleotide, which tends to be longer than a monomer nucleotide, contains many variations of arrangements of A, C, T, and G.…

    A DNA molecule which is the abbreviation for deoxyribonucleic acid is made up of precise lengthy chains of polymers and monomers and they are called nucleotides. These two (2) chains specifically which are composed of DNA strain are then molded by the grouping of the nucleotides into the polynucleotides. The nucleotide is composed of a nitrogenous base, a phosphate and a group. In DNA there are four (4) nucleotides that can be found along the DNA chain. These four (4) nucleotides are (T) thyme, (A) adenine, (C) cytosine, and (G) guanine. These four (4) nucleotides are fused together by their covalent bonds. In other words the sugar and the phosphates which composes the sugar/phosphate support of the polynucleotide.…

    The Most Dangerous Game Conflict Analysis

    It is commonly believed that if you are in a position of power and authority you will always remain so. In his fictional short story, “The Most Dangerous Game,” Richard Connell’s characters, Sanger Rainsford and General Zaroff, had the same opinion. Like many individuals, neither men ever expected to be placed in a position of weakness. The deadly conflict that led to both Rainsford and Zaroff hunting and being hunted developed the theme, “strength and power are temporary,” because two once powerful men suddenly fell.…

    Using DNA in Science and Technology

    DNA is the blueprint for life, it is found in the nucleus of cells on the chromosomes. It is found in many cell organelles, such as plasmids in bacteria, chloroplasts in plants, and mitochondria in both plants and animals. DNA helps us to perform many actions in solving crimes, and also helps us to do scientific studies that were not possible until recently. DNA has a double helix structure, its sugar phosphate backbone, made up of deoxyribose and a phosphate group are held together by hydrogen bonds and base pairs. These bases are adenine and guanine, thymine and cytosine. There are coding and non coding parts of DNA, the non coding part is called an intron, this may not seem to have a function but it helps to keep the structure of the helix by coiling, regulates when genes are expressed and is also used in DNA replication. Non-coding regions of DNA between genes are the satellite DNA, this is a simple base sequence repeated many times. It’s not all non-coding DNA though, the coding parts of the DNA are known as exons.…
