Term Definition
Griffith discovers that a factor in heat-killed, disease-causing bacteria into ones that can cause disease
Avery determines that genes are composed of DNA
Hershey concluded with Chase that the genetic material of the bacteriophage was DNA
Chase conculded with Hershey that the genetic material of the bacteriophage was DNA
Watson & Crick developed the double helix model of the structure of DNA
Chargoff showed that the percentage of guanine and cytosine are almost equal; the same is true for adenine and thymine
Nucleotide Structure has 3 parts= a phosphate group, deoxyribose group, and a nitrogenous base; the four different bases in DNA are adenine, thymine, guanine and cytosine
DNA Structure DNA is a double helix in which 2 strands are wound around eachother; each strand is made up of a chain of nucleotides, the 2 strands are held together by the hydrogen bonds between adenine and thymine and between guanine and cytosine
DNA Replication during DNA replication, the DNA molecule produces 2 new complementary strands. each strand of the double helix of DNA serves as a template for the new strand
DNA Polymerase the principal enzyme involved in DNA replication; it joins individual nucleotides to produce a DNA molecule
Protein Synthesis three main types of RNA: mRNA, rRNA, & tRNA; ribosomal RNA is combined with proteins to form ribosomes
Transcription RNA polymerase binds to DNA and seperates the DNA strands, RNA polymerase then uses one strand of DNA as a template from which nucleotides are assembled into a strand of RNA
Translation the cell uses the info form the mRNA to produce proteins
Histones Tthe DNA that is tightly coiled around protiens
Chromatin eukaryotic chromosomes contain both DNA and protein tightly packed together to form chromatin
mRNA RNA molecules that carry out copies of instruction for assembling amino acids into proteins
rRNA ribosomes are made up of several dozen proteins as well as a form of RNA
tRNA transfers each amino acid to the ribosome as it is specified by coded messages in mRNA
Codon 3 nucleotide sequence on mRNA that codes for a single amino acid
Amino Acid compound with an amino group on one end and a carboxyl group on the other end
Exons expressed sequence of DNA; codes for a protein
Introns sequence of DNA that is not involved in coding for a protein
Mutations Point Mutations=involving changes in one or a few nucleotides; occur at a single point in DNA sequence: frameshift mutations=shifts the "reading" frame of the genetic message by inserting or deleting a nucleotide
