DNA As Chemical Beacause Of Its Structure

322 Words2 Pages

Firstly, DNA as chemical beacause of its structure and all the molecules that made it up. As I mentioned before, DNA is a nucleic acid and it is one of the main type of nucleic acids differing from the other in the type of sugar that forms its polymeric backbone. In this case of DNA, it is formed by 2’-deoxyribose sugar. Moreover, nucleotides are the subunits of DNA (a long chain of nucleotides) consist of a nitrogenous base (purine or pyrimidine), a sugar and a phosphate. In nucleotides, one of several different nitrogen-containing ring compounds (bases) is linked to a five-carbon sugar that carries a phosphate group. The backbone of the polynucleotide chain consists of an alternating series of pentose (sugar) and phosphate residues, via 5'-3'

    Deoxyribonucleic acid (DNA) is a molecule found in all forms of life that is passed down from parents to offspring. What makes each DNA unique is the chemical makeup of the molecule sometimes referred to as the “blueprint of life.” (BIO). DNA is made up of nucleotides consisting of a sugar, a phosphate and a base pair. About six million nucleotide base pairs make up DNA in each cell.

    For most sequences at position 4 and 5 we observe only the nucleotides G and T, respectively. There may be rare cases where other nucleotides may also be found. To consider such observations, we need to do a process called additive smoothing or Laplace smoothing to smooth the categorical data. [9] In this case, we add 4 sequences: AAAAAAAAA, CCCCCCCCC, GGGGGGGG, TTTTTTTTT.

    1a. Review: Describe three main differences between RNA and DNA. The three main differences between RNA and DNA are as follows: RNA has the sugar ribose instead of deoxyribose, which DNA has, RNA is single-stranded while DNA is double-stranded, and RNA uses uracil instead of thymine. 1b.

    The biochemistry is very similar through all organisms with each containing DNA made from adenine, thymine, guanine, and cytosine. First, the DNA is transcribed into mRNA. That specific RNA is then converted into an amino acid sequence by ribosomal RNA. The amino acid code makes up a polymer that ultimately becomes the protein that constructs the organism’s distinctiveness. That is how the given organisms establish their physiognomies.

    The monomers of lipids are fatty acids and glycerol. When lipids bond with phosphorous, it creates a phospholipid, which is what is used to create your cell membranes. Nucleic acid is very important because it determines who you are. If there weren’t nucleic acids, we wouldn’t be able to have children because there would be no way to determine their genetics. Nucleic acids are also very good to eat because they contain phosphorous and nitrogen, which are also in other macromolecules.

    1. How does DNA encode information? DNA is a double-stranded helix composed of a phosphate backbone and deoxyribose, and encodes information by the sequence of its nucleotide bases, which are composed of adenine, thiamine, guanine and cytosine. DNA undergoes transcription, which produces single-stranded mRNA, which uses uracil in place of thiamine. Next step is translation, in which the RNA becomes a protein, which then can act as structural units or enzymes.

    DNA is who we are, it also identifies who we are. Repetitive DNA makes up most of the DNA, which is used in forensic DNA analysis. Within the DNA there is a repeating series that’s known as the STR ( short tandem repeat). Everyone is different with the number of repeats, but have the same sequence in the same places. The STR can identify an individuals DNA profile.

    DNA in Forensic Science DNA is the carrier of genetic information in humans and other living organisms. It has become a very useful tool in forensic science since it was discovered. In forensic science, DNA testing is used to compare the genetic structure of two individuals to establish whether there is a genetic relationship between them. One example of the use of DNA in forensic science that is important in biology today is comparing a suspect’s DNA profile to DNA that was discovered at a crime scene.

    DNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.

  • Double Helical Structure Essay

    2085 Words  | 9 Pages

    Each strand of the DNA has a sugar-phosphate backbone. The deoxyribose sugar and phosphate group are joined together by phosphodiester bonds. To hold the two strands together to form a DNA molecule, hydrogen bonds are present between two complementary bases on the different strands. Each nitrogenous base pairs with a complementary partner; Adenine pairs with Thymine with double hydrogen bonds; Guanine pairs with Cytosine with triple hydrogen bonds. Factors affecting the double-helical structure of DNA Besides having hydrogen bonds between the bases to hold the two DNA strands together, the backbone of the polynucleotides must be highly charged too.

  • The Pros And Consequences Of DNA Fingerprinting

    The chemical structure of everyone's DNA is the same. The only difference between people (or any animal) is the order of the base pairs. There are so many millions of base pairs in each person's DNA that every person has a different sequence. Using these sequences, every person could be identified solely by the sequence of their base DNA fingerprinting also called DNA Typing in genetics is the method of isolating and making images of sequences of DNA (deoxyribonucleic acid). The technique was developed in 1984 by the British geneticist Alec Jeffrey’s, after he noticed the existence of certain sequences of DNA (called mini satellites) that do not contribute to the function of a gene but are repeated within the gene and in other genes of a DNA sample.
