PPT-Nucleotides. Nucleic Acid, and Heredity

What Are the Molecules of Heredity After scientists became aware of the differences in amino acid sequences their next quest was to determine how cells know which proteins to synthesize out of the extremely large number of possible amino acid sequences The answer is that an individual gets the information from its parents through . THE STUFF OF LIFE. Biomolecules. Organic molecules made up of:. Carbon. Hydrogen. Nitrogen. Oxygen. a. nd sometimes Phosphorus. LATIN 101. Poly = . Many. Mono = . O. ne. Hydro = . Water. . (actually Greek). Nucleic Acids. What do we know already?. i. . The nucleic acids DNA and RNA are polymers of nucleotides. Nucleotides consist of 3 parts. A 5-carbon sugar – ribose or deoxyribose. A phosphate group (acidic & negatively-charged). 1-deoxyribonucleic acid (DNA). 2-Ribonucleic acid (RNA. Nucleic. Acids. Structure: Nucleotide. Monomer : . Nucleotide. A pentose sugar molecule .. 2.A phosphate group .. 3.A nitrogenous base .. Monomer : . Essential idea: The structure of DNA allows efficient storage of genetic information.. There is 2m of DNA in each human cell, however the most cells in the human body have a diameter of 10 . μm. . This DNA is divided in chromosomes and coiled around proteins called histones so that it can be efficiently stored in each cell's nucleus. The human genome project which has decoded the case sequence for the whole 2m of the human genome requires a data warehouse (pictured) to store the information electronically. This should give a good idea of just how efficient DNA is at storing information and why it needs to be so.. Presentation for . Massachusetts Association of Technology Transfer Offices.

Heredity is the cause of similarities between individuals. This is the reason that brothers and sisters with the same parents resemble each other and with their parents. Variation is the cause of differences who do resemble each other are still unique individuals. Thus, we have no trouble in recognizing the differences between sisters, for example, and even ‘identical’ twins are recognized as distinctive individuals by their parents and close friends. . , Function & Repair .
