Protein vs. DNA controversy
|
controversy over where the genetic information was carried
|
|
|
Structure of DNA
|
it is a double helix with phosphate sugar backbone and hydrogen bonds.
|
|
|
DNA replication
|
Happens in the nucleus before a cell splits, it makes a exact copy of the DNA. Helicase untwists DNA, SSBP holds it open, while DNA Polymerse cuts it, copies, and checks for errors.

|
DNA vs. RNA
|
1. DNA has thymine and RNA has uracil
2. DNA has double helix and RNA is single strand 3. DNA stays in nucleus and RNA leaves nucleus. |
|
|
Transcription including RNA Editing
|
Happens in nucleus and all the time for protein production. DNA→ RNA and in RNA editing introns are removed, exons connected and RNA → mRNA and then it leaves the nucleus.
|
|
|
Translation
|
Happens in cytoplasm and all the time for protein productions. MRNA → amino acid. TRNA carries amino acids and pairs with mRNA where the amino acid chain builds and builds
