COMPARE DNA, GENES, AND CHROMOSOMES: Function: *All three use genetic information *Genes and DNA are needed to develop information on an organism *Genes and Chromosomes have to do with proteins
Structure: DNA looks like a twisted ladder where two strands twist around each other which is called a double helix. Genes contain DNA so the structure of them are really the same. There are different forms of genes that produce different traits, these are all called alleles. The chromosome groups form an X shape, with the structure of DNA on the inside.
DIFFERENCES IN STRUCTURE OF DNA, mRNA, AND tRNA: DNA is double stranded while RNA is typically single stranded. DNA has a sugar of deoxyribose in it, while RNA has the sugar of ribose. DNA contains thymine, while RNA contains uracil. RNA is a strand while DNA is two twisted strands.

CONTRAST DNA, GENES, AND CHROMOSOMES: Function: *DNA copies, stores, and transmits genetic information *Genes determine traits of a person *Chromosomes bundle genetic information
Structure: Chromosomes (inside of cell) have a structure where they are located in a group. These groups form an X shape. DNA is made into a long chain of nucleotides and is seperated into three dimensions.
DIFFERENCES IN FUNCTION OF DNA, mRNA, AND tRNA: DNA stores, copies, and transmits genetic information in a cell, while mRNA carries the DNA to the other parts of the cell, and tRNA carries a mino acids to the ribosome and matches them to the coded mRNA message.  |
