Describe The Structure Of Dna

Improved Essays
A. The structure of DNA is that DNA is made up of a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction and thats is called nucleotides. Each nucleotide contains a phosphate group. phosphate is a chemical and salt of phosphoric acid. DNA is also a sugar group and a nitrogen base. There are four types of nitrogen bases which are adenine (A), thymine (T), guanine (G) and cytosine (C). This order determines DNA's instructions or genetic code. The function of DNA is Deoxyribonucleic acid, which is a organic substance present in living cells and contains the genetic instructions for the development and function of living things. The main role of DNA in the cell …show more content…
Helicases are enzymes that bind and may even remodel nucleic acid protein complexe. There are both DNA and RNA helicases. Codon is a sequence of three nucleotides that form a unit of genetic code in a DNA or RNA molecule. Polymerase is a enzyme that brings the formation of a particular polymer. A five cap is a specially altered nucleotide on the five. Poly (A) tail is a long row of 100-250 adenine nucleotides. Introns is the selection of primary transcript not in the mRNA. Exons are regions of eukaryotic genes that are part of the final mRNA. A spliceosome is a large and complex molecular machine found primarily within the splicing (a process b which introns are removed from the growing RNA stand, then pieces of primary transcript are removed and the remaining segments are joined together) speckles of the cell nucleus of eukaryotic cells. rRNA is a molecular component of a ribosome, the cells protein factory. tRNA are molecules that carry amino acids to the ribosome for polymerization (a process of reacting monomer molecules together in a chemical reaction to form polymer chains) into a polypeptide. mRNA is a subtype of RNA which carries a portion of the DNA code to other parts of the cell for processing. Ribosomes are a minute particle consisting of RNA and associated proteins and found in large numbers in the cytoplasm of living cells. Anticodon is a sequence

    5. Ribosomes are involved in protein synthesis, in other words they create proteins. 6. mRNA attaches one end to a ribosome, and through codons, tRNA brings in amino acids and attaches them together to form a specific protein polymer. Codons code for amino acids, and are "triplets" of code.…

    These ribosomes move through the mRNA to generate new subunits of proteins. tRNA and mRNA sequences interact through codons and anticodons and tRNA is what brings amino acids for the use of the ribosomes in translation; therefore, amono acids continue to be made as long as there is availability of resources until a stop codon is hit which is what stops the translation. Different types of amino acids are made for different things; therefore, naturally, these types of amino acids must be made through the process of translation. Through the use of a simple chart of genetic code triplets, it is possible to find out which coding sequences of mRNA correspond to which amino acids; therefore, it is easy to see the outcome of translation without actually diving into genes. Sixty four total codons exist that correspond to polypetides and…

    1. DNA Structure and Function DNA is the type of organic compound that stores the genetic information in a living organism. DNA is made up of two strands of nucleotides, which include a phosphate group, five carbon sugar, and a nitrogenous base. Each individual strand in held together by strong covalent bonds (a bond formed as a result of the distribution of electrons between atoms). The two strands are then joined to each other by hydrogen bonds between complementary bases.…

    A nucleotide is made up of three things. It consists of a nitrogenous base made up of either adenine, cytosine, guanine or thymine. The nucleotide also contains either the sugar deoxyribose or ribose. Finally, it contains one or more phosphate groups. Nucleotides bond together and form a double helix, which was discovered by scientists Francis Crick and James Watson in 1956.…

    The role of nucleic acids are to store, express, and transmit genetic information. A nucleotide is an organic molecule having three components: one or more phosphate groups, a five carbon sugar, and a single or double ring of carbon and nitrogen atoms. Two types of nucleic acids are DNA and RNA. RNA. The structure of DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.…

    Amino acids have a trio of tRNA on them. tRNA is just three nitrogenous bases. When mRNA is on the ribosome, it is understood that the nitrogenous bases are set into groups of three. These are called codons. Codons are already pre-determined by a triplet that was formed by the original DNA.…

    The arrangement of DNA and RNA bases dictates what protein is formed. When DNA is separated into a single strand, ribonucleotides attach to one of the strands and form messenger RNA (mRNA), through the process of transcription. When the gene is turned into a protein sequence by transfer RNA (tRNA), it is called…

    Genes are the basic physical and functional unit of heredity, and make up DNA, acting as instructions for the production of proteins in the organism of every living thing. DNA (deoxyribonucleic acid) is condensed and packaged around histones, which order it into units known as nucleosomes. The epigenome is made up of chemical compounds and proteins that can attach to DNA and switch certain genes on or off, controlling the functions and roles of different cells. Epigenetics, which involves genetic control by factors outside of the DNA sequence, can switch genes on or off and determine how proteins are copied and the roles they have in certain cells. Though DNA can be compared to the harddrive on a computer, epigenomes are more flexible and can determine how genes function,…

    Proteins are large, complex molecules found throughout the body. They are polymers made out of different types of small unites called amino acids. Each amino acid consists of a central carbon atom, which is attached to a hydrogen atom, an amino group, a carboxyl group, and a unique side chain or R group. There are twenty different types of amino acids and each one of them has different chemical properties. Amino acids are held together by covalent peptide bonds therefore the proteins, chains of amino acids, are also called polypeptides.…

    This process is called transcription. The newly created mRNA leaves the nucleus through the nuclear pores and goes out into the cytoplasm. A ribosome attaches to the mRNA and begins the process of translation, which is continued in the segment on ribosomes and their function. The other part of the nucleus is the nucleolus. The nucleolus is mainly responsible for ribosome synthesis.…

    Within the process of protein synthesis, the categorization that occurs in the DNA is transliterated onto the single strand, which takes place as the "messenger" of the RNA; this is referred to as the mRNA. The next step in this cycle is when the mRNA is moved to the ribosome. Here we are now introduced to the rRNA, which is responsible for the processing of protein synthesis. Following the rRNA, we have the tRNA. The tRNA is known for carrying out the amino acids different areas of the cell, which is placed in the ribosomes.…

    This part of protein synthesis occurs in the ribosome. The mRNA codon fixes itself to the ribosome. The tRNA (transfer RNA) has to bond with a correlative mRNA codon. Next, the amino acid is detached from the tRNA by an enzyme. Lastly, when the ribosome reaches to a “stop” codon, it frees the mRNA and it also releases a string of amino acids.…

B) Insulin is made in the DNA when the mRNA copy’s a specific strand/section of the DNA in this case the mRNA begins at Glycine-GGU and ends at Asparagine-AAU this is the basis of human insulin. The tRNA strand then joins the mRNA to the specific amino acid for example tRNA links the start of insulin Glycine (amino acid ) to GUU (mRNA strand from DNA) by doing this it creates a long chain of amino acids which then forms a protein.…
