DNA Worksheet Essay Sample

1. Describe the construction of DNA.

A Deoxyribonucleic acid molecule which is abbreviation for deoxyribonucleic acid is made up of really long ironss of monomers and polymers that are called bases. These two ironss in peculiar which composes of DNA strain are so formed by the grouping of the bases into the polynucleotides. The base is made up of a nitrogen-bearing base. of sugar and of a phosphate group. In the DNA instance. there are four bases that are found along the Deoxyribonucleic acid concatenation. the four bases Ate ( T ) thyme. ( A ) A. ( C ) C. and ( G ) G. These four bases 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 find its phenotype?

The genotype of an being is the familial make-up of that being. it is the nucleotide bases in the organism’s DNA. The phenotype is considered the physical traits of the being which comes from the actions of the wide assortment of proteins. The organic structure of an being 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 Deoxyribonucleic acid. However. a protein is non straight built by a cistron. but dispatches the instructions to make so in the signifier of the RNA. which in bend plans the synthesis of the protein.

3. Describe each phase of the flow of information get downing with DNA and stoping with a trait.

“A sequence of bases in the Deoxyribonucleic acid is transcribed into a molecule of RNA in the cell’s karyon. The RNA travels to the cytol. where it is translated into the specific amino acerb sequence of a protein. ” ( Eric J. Simon. Jane B. Reece. and Jean L. Dickey )
