Function of RNA
Messenger mRNA
Ribosmal rRna
Transfer tRNA
texting tRNA
Ribosmal rRna
combine cRNA
Messenger RNA
Takes DNA code from the Nucleus to Ribosome
Takes DNA code from the Ribosome to Nucleus
Takes DNA code from the Nucleus to Protein
Transfer RNA
Translates the mRNA code into a string of amino acids to create proteins
Translates the rRNA code into a string of amino acids to create proteins
translates the tRNA code into a string of amino acids to create proteins
Ribosomal RNA
makes up ribosomes and serves as the place where proteins are assembled
makes up DNA and serves as the place where proteins are assembled
makes up ribosomes and serves as the place where proteins are disassembled
Transcription
Process by which DNA is used to make a single stranded complementary mRNA molecue using DNA as template U's instead of T's
Process by which RNA is used to make a single stranded complementary DNA molecue using DNA as template U's instead of T's
Codons
3 mRNA base sequences that make a 3 letter words, that specify a single amino acid to be added to the polypeptide chain
4 mRNA base sequences that make a 4 letter words, that specify a single amino acid to be added to the polypeptide chain
Since their are a four bases in RNA
There are 64 possible different codons or different base sequence
There are 44 possible different codons or different base sequence
There are 90 possible different codons or different base sequence
There are 13 possible different codons or different base sequence
Translation
Process of decoding mRNA message into a protein
Process of decoding DNA message into a protein
Process of making mRNA message into a protein
What uses the sequence of codons in mRNA to assemble amino acids into polypeptide chain
Ribosomes
Nucleus
Lysosome
First step of translation
when ribosome attaches to a mRNA
when ribosome attaches to a tRNA
As the Ribosome reads each codon in mRNA
it directs tRNA to bring the specific amino acid into the ribosome
it directs rRNA to bring the specific amino acid into the ribosome
Anticodon
each tRNA molecule has three unpaired bases, which is complementary to one mRNA codon
each rRNA molecule has three unpaired bases, which is complementary to one mRNA codon
each tRNA molecule has three unpaired bases, which is noncomplementary to one mRNA codon
Each tRNA molecule
carries just one kind of amino acid
carries two kind of amino acid
carries three kind of amino acid
tRNA Continuously
pulls amino acids from the cytoplasm
pulls lipids from the cytoplasm
pulls starches from the cytoplasm
Ribosome
puts peptide bonds between amino acids as they are brought in
puts covalent bonds between amino acids as they are brought in
puts hydrogen bonds between amino acids as they are brought in
"Stop" Codon
Polypeptide chain stops growing as soon as it reaches a Stop codon on the mRNA sequence
Polypeptide chain keeps growing as soon as it reaches a Stop codon on the mRNA sequence
