GenesProteins
How does DNA create proteins?
Initial hypothesis: DNA acts as an enzyme
DNA structure regulated (hydrogen bonds throughout molecule)
DNA cannot bind to many substrates
DNA Enzyme
Conclusion: DNA code, information storage
What is the path from DNA to proteins?
DNA present in nucleus +
proteins present in cytoplasm
Must be intermediary between DNA and
proteins
Intermediary = mRNA
Overall summary:
DNA acts as information storage, and is transcripted to mRNA by RNA
polymerase
mRNA acts as an information carrier, and is translated to proteins by ribosomes,
