DNA Topics Survey
 
 

 
The secret is out.
Please check each of the statements to the right that you believe are true.
DNA is shorthand for deoxyribonucleic acid.
DNA defines our physical characteristics, including what we look like, diseases we are susceptible to, intelligence, etc.
DNA is partly responsible for our behavior because it determines how we react and assimilate to our environments, learning and teaching.
DNA is passed on from one generation to the next.
DNA is present in all organisms from the smallest virus to the largest animals.
DNA is the only known molecule that has the ability to replicate itself.
About this survey:  The points below are intended to provide a basic overview of some fascinating genetic chemistry. You are invited to review the points below. Try checking each button to the right as you proceed in your understanding. Please do not check the buttons to the right of concepts that are not clear enough for you to understand. OK
1.  All living organisms are composed of cells. Nuclei of cells contain long threads of nucleic acids and proteins called chromosomes. Chromosomes contain hereditary information that directs the growth, development, and activities of all cells. OK
2.  DNA is a biological blueprint that contains instructions for all characteristics of all organisms. That information is transferred from a DNA molecule into an RNA molecule in a process called transcription. OK
3.  DNA stands for deoxyribonucleic acid. DNA takes the form of long strands. Each DNA strand is a long polymer built of millions of nucleotides that are linked together. OK
4.  DNA is unique among all known molecules. It is the only one capable of duplicating itself. The process of duplication is called replication. Replication is the process where two complementary strands which form the DNA molecule unzip. Then each is used as a template to make new new strands as free nucleotides combine with their complementary bases. OK
5.  RNA is an acronym for ribonucleic acid. There are many forms of RNA. They are all similar to DNA. All types of RNA are formed from DNA in a process called transcription. OK
6.  The information that DNA and RNA carries is written in a genetic code. This code is made of a sequence of bases. The code is like a sentence, but instead of a string of words it consists of a series of letters. Each code is called a codon and is a sequence of three nucleotides that specify one of twenty amino acids. There are 64 possible codons (4 x 4 x 4) and each codon carries codes for an amino acid. The letters used to build codons are U, C, A, G. OK
