DNA Worksheet

Answer the following in at least 100 words:

1. Describe the structure of DNA.

A DNA molecule which is abbreviation for deoxyribonucleic acid is made up of very long chains of monomers and polymers that are called nucleotides. These two chains in particular which composes of DNA strain are then formed by the grouping of the nucleotides into the polynucleotides. The nucleotide is made up of a nitrogenous base, of sugar and of a phosphate group. In the DNA case, there are four nucleotides that are found along the DNA chain, the four nucleotides ate (T) thyme, (A) adenine, (C) cytosine, and (G) guanine. These four nucleotides are joined together by their covalent bonds, or more specific, the phosphates and the sugar which composes the sugar/phosphate back bone of the polynucleotide.

2. How does an organism’s genotype determine its phenotype?

The genotype of an organism is the genetic makeup of that organism, it is the nucleotide bases in the organism’s DNA. The phenotype is considered the physical traits of the organism which comes from the actions of the broad variety of proteins. The body of an organism is made up by the structural proteins and the metabolic activities are catalyzed by the enzymes. The synthesis of the proteins is specified by the DNA. However, a protein is not directly built by a gene, but dispatches the instructions to do so in the form of the RNA, which in turn programs the synthesis of the protein.

3. Describe each stage of the flow of information starting with DNA and ending with a trait.

“A sequence of nucleotides in the DNA is transcribed into a molecule of RNA in the cell’s nucleus. The RNA travels to the cytoplasm, where it is translated into the specific amino acid sequence of a protein.” (Eric J. Simon, Jane B. Reece, and Jean L. Dickey)

    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.…

    The genotype is the genetic makeup of a cell, an organism, or an individual usually with reference to a specific character under consideration. A phenotype is the composite of an organism's observable characteristics or traits: such as its morphology, development, biochemical or physiological properties, phrenology, behavior, and products of behavior. Phenotypes result from the expression of an organism's genes as well as the influence of environmental factors and the interactions between the two. Genotype means all the genes in a species DNA. Phenotype is what you would see in a species. Reactions involve the formation of products that are functioning in the cell for various things such as structural support, fibers, cytoskeleton, channels on membrane, enzymes that metabolize food molecules like glucose, energy production, transport, signal systems, pigmentation, attachment to other cells and various others.

    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 made up of two strands. At one end of each strand there is a phosphate group attached to the carbon atom number 5 of the deoxyribose (this indicates the 5' terminal) and at the other end of each strand is a hydroxyl group attached to the carbon atom number 3 of the deoxyribose (this indicates the 3' terminal). The strands run in opposite directions and so we say that they are antiparallel. One strand runs in a 5'-3' direction and the other runs in a 3'-5' direction. Adjacent nucleotides are attached together via a bond between the phosphate group of one nucleotide and the carbon atom number 3 of the deoxyribose of the other nucleotide.…

    DNA consists of two polynucleotide chains and these nucleotides consist of a deoxyribose sugar, a nitrogenous base and a phosphate group. The bases are Adenine, Cytosine, Guanine and Thymine. The sequence of these bases on DNA determines the structure of these proteins. A gene is a sequence of bases which codes for a single polypeptide. Chromosomes carry these genes and these genes come in specific forms called an allele which is how living organisms vary from each other. For example, humans are made up of an XY or XX chromosome. Females are XX and males are XY, however in some animals their sex is determined by the ZW sex-determination…
