Dna and Mrna
What is the shape of DNA
Twisted double helix
Using a codon wheel what does CAG=
Glutamine
what does MRNA stand for?
Messenger RNA
Where does Transcription take place
The Nucleus
What is the first step to make a protein
Transcription
What is the shape of Mrna
a single strand
What do you use the codon wheel for
Find amino acids
What does TRNA stand for?
Transfer RNA
What is Transcription role in protein synthesis
Its the first step for protein synthesis
what is the second step to make a protein
Translation
What is the sugar for Mrna
Ribose
Using a codon wheel what does G-G-A-T-C-G transcribe to
C-C-U-A-G-C
What does Rrna stand for?
Ribosomal RNA
What does Transcription do
It turns DNA into mRNA
What are proteins
Biomolecules
How are DNA and mRNA alike?
They are both nucleic acids
They are both found in the nucleus
DNA and MRNA both have 3 of the same Nitrogen bases (A,G,C)
Using a codon wheel which codons =stop
UAA UAG UGA
what is Mrna purpose?
Carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell
What two enzymes help during Transcription
Helicase and RNA polymerase
What are proteins made of
amino acids and monomers
How are the accuracy of DNA and mRNA codes assured ?
proofreading molecule
Using a codon wheel which codon= the start
AUG
What is the purpose of Trna?
Transfers amino acids to ribosomes during protein synthesis
What happens after Transcription
The mRNA leaves the nucleus and travels to the ribosomes in the cytoplasm.
can proteins be enzymes
yes they can
