translation
the decoding of a mRNA message into a protein(peptide chain)
3 phases of translation
initiation, elongation, termination
genetic code
each codon specifies a particular amino acid that is to be place in the polypeptide chain
codon roles
AUG is called an "initiation codon",
There are also 3 "stop" codons, they do not code for an amino acid.
AUG
is a start codon
3 major codons
UAA, UAG, UGA
DNA
TAC, AAA, TTT, CAG, AAC, TTC, CAT
mRNA
AUG, UUU, AAA, GUc, UGG, AAg, GUA
tRNA
UAC, AAA, UUU, CAG, AAC, UUC, CAU
Polypeptide
met, phe, lys, val, leu, try, val
mRNA, enzymes
Translation of mature____________requires several, ______________, tRNA, and rRNA.
single-stranded, onti codon

nucleic acide, proteins
Changing 1 language to another:____________~Polypeptides____________
complementary
The anticodon is _____________to the corresponding mRNA codon.
proteins
made up of amino acids
amino acids
Proteins differ in the number and sequence of ___________.

3 combinations on mRNA are called ___________.
Nucleic Acids & Protein Synthesis
DNA, RNA, and Protein Synthesis
protein
DNA~RNA~ ________________
DNA & RNA
____________are directly responsible for making proteins.
I.
Smooth colony(disease) was injected in mouse so mouse died.
DNA~RNA~Protein
What is the Central Dogma of Molecular Biology?
II.
Rough colony was injected in mouse so mouse lived.
III.
When heat smooth colony was injected mouse lived.
IV.
Injected the heat-killed type and the non-deadly rough type bacteria. The deadly bacteria "transformed" itself from the heated non-deadly type to the deadly type. Rat died.
THey found out DNA was the transforming facts.
Briefly describe how Aver, McCarty and McLeod further developed Griffiths experiment.
They put non-deadly rough type no heat-killed smooth type which put in different test types which had different enzymes that destroyed various organic molecules.
Explain the experiment and the results of the Hershey-Chase experiment, which is visualized below.
Equal amount of ademine and Thymine, and equal amounts of Guanine and Cytosine
According to Chargaff's rule, how do the bases of DNA pair with one another?
One is purine and pyrimidine fit in the latter
Why do they pair in this way.
twisted ladder
What about DNA did this image reveal?
Watson and Crick
Who won the race to discover DNA's structure?
Phosphorous and deoxyribose four nucleotides, denine, thymine, guadanine and cytosine
What is the backbone of DNA made of?
genetic code
manner in which cells store program that they pas form one generation the the next
transformation
process by which genetic material absorbed from the environment is added to or replaces part of bacterium's DNA
DNA
nucleic acid that stores & transmits genetic information from one generation to an organisms to the next by coding for the production of a cell's proteins.
nucleotide
unit of a nucleic acid that is made up a f-carbon sugar, a phosphate group, and a nitrogenous base
adenine
nitrogenous base in nucleic acids, belonging to the purines; base pairs with thymine or uracil
guanine
nitrogenous base in nucleic acids belonging to the purines; base pairs with cytosine
cytosine
nitrogenous base is nucleic acids belonging to the pyrimidines; base pairs with guanine
thymine
nitrogenous base found in DNA but not in RNA; base pairs with ademine
base pairing
attraction between complementary nitrogenous bases that produce a force that holds the two strands of the DNA double helix together
replication
process by which DNA is duplicated before a cell divides.
RNA
nucleic acid made up of a single chain of nucleotides that acts as a messenger between DNA and the ribosome and carries out the process by which proteins are made from amino acids.
uracil
nitrogenous base found on in RNA;base pairs with adenine
transcription
process by which a molecule of DNA is copied into a complementary strand of RNA.
messenger (RNA)-
of RNA that carries genetic information from DNA in the nucleus out to the ribosomes in the cytoplasm.
codon
3 nucleotide sequence on messenger RNA that codes for an amino acid
translation
process in which a message carried by messenger RNA is decoded into polypeptide chain(protein)
transfer RNA
type of RNA that carries amino acids to the ribosomes where the amino acids are joined together to form polypeptides
