What is the outcome of DNA replication in terms of the strands?
What is the role of helicases in DNA replication?
Why do single strand binding proteins stabilize the unwound DNA during replication?
How does DNA polymerase synthesize a new DNA strand?
What is the significance of DNA replication being semi-conservative?
How are Okazaki fragments joined together to form a complete lagging strand?
What is the purpose of DNA replication?
What is the role of primase in DNA replication?
What is the difference between primase and DNA polymerase?
What is the relationship between helicase and primase in DNA replication?
What factors can influence gene expression?
What does it mean for a gene to be "switched on"?
What does it mean for a gene to be "switched off"?
How does the environment affect gene expression?
Transcription of DNA to RNA --> Expression
A specific region on the DNA codes for a specific protein --> gene
First step --> Transcription of DNA into RNA. This step is gene expression. Second step --> RNA molecule is transported to the cytoplasm and here the RNA will be translated into protein. Proteins are the main work horses in molecular biology.
What is the first step in gene expression?
What happens to the RNA molecule after transcription?
What is the second step in gene expression?
Where does the translation of RNA into protein occur?
What is the role of proteins in the cell?
What is the function of genes?
What can RNA polymerase do while sliding along the DNA?
What does RNA polymerase do while copying the DNA?
What is the end result of RNA transcription?
