Studied by 2 peopleWhich scientist conducted tests on extracts made of bacteria to show that the genetic material in bacteria is DNA?
Oswald Avery
Who was responsible for the experiment depicted by the image/data table?
Frederick Griffith
If Chargaff found that a sample of DNA has 30% THYMINE, how much GUANINE would he have calculated to be there?
20%
Who was responsible for the experiment depicted by the image?
Rosalind Franklin
What did Erwin Chargaff conclude from his experiments?
A and T, C and G always occur in equal amounts
Rosalind Franklin's "Photo 51" allowed Watson and Crick to determine the ___ of DNA.
Shape
From his work with mice and pneumonia-causing bacteria, Frederick Griffin coined the term
Transformation
The work of scientists including Griffin, Avery, Hershey & Chase and Franklin helped us to determine the __ are responsible for carrying genetic material.
Nucleic Acids
By using radioactive isotopes, Hershey and Chase were able to conclude that __ is/are the carrier(s) of genetic information.
DNA
Scientist Griffith mixed dead, virulent, pneumonia-causing bacteria with living, harm-less bacteria. The harmless bacteria than infected mice with pneumonia. This experiment showed the process of....

nitrogen base pairing
If Chargaff found that a sample of DNA has 20% ADENINE, how much GUANINE would he have determined to be there?
30%
What was Watson and Crick's main scientific accomplishment?
Building the first accurate 3D model of DNA
transcription
the process where the DNA sequence in a gene is copied into mRNA
translation
the process where genetic information coded in mRNA directs the formation of a specific protein at a ribosome
mRNA
type of RNA that carries instructions from DNA in the nucleus to the ribosome
tRNA
type of RNA that carries amino acids to the ribosome
codon
sequence of three bases on a strand of mRNA that provides genetic code information for a particular amino acid
complementary base pairing
In DNA, T pairs with A; G pairs with C; RNA, U pairs with A and G pairs with C
ribosome
Organelles at which proteins are synthesized. Made of rRNA
nucleus
A part of the cell containing DNA. DNA can not leave.
amino acid
Building block of protein. There are 20 types.
adenine
pairs with uracil in RNA, thymine in DNA
cytosine
pairs with guanine
nitrogenous bases
adenine, guanine, cytosine, thymine, uracail
deoxyribose
sugar in DNA
ribose
sugar in RNA
nucleotide
consists of a phosphate group, sugar, and nitrogen base
DNA
A double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins.
RNA
A nucleic acid that carries information from DNA to ribosomes
