12 Questions
What is the main difference between the sugar-phosphate backbone of DNA and RNA?
RNA has 1 sugar-phosphate backbone, while DNA has 2
What is the base pairing rule for RNA?
A-U, C-G
What is the role of RNA polymerase in the process of transcription?
It uses the DNA as a template to make messenger RNA
What happens to the messenger RNA after it leaves the nucleus?
It travels through the cytoplasm and attaches to a ribosome
What is the result of a mutation in the DNA base sequence?
A variation in the amino acid sequence
What is the function of the ribosome in the process of translation?
It translates the mRNA into a protein
What is the result of the abnormal hemoglobin in red blood cells?
Sickle-shaped red blood cells
What is the sequence of events that leads to the production of abnormal hemoglobin?
DNA replication, mRNA transcription, ribosome reading, protein creation
What is the reason why sickle cell disease is more common in people of Afro-Caribbean origin?

Model 2, where the yeast cell lets the polymerase transcribe the spider's DNA to turn it into mRNA
What is the purpose of the ribosome in the process of protein creation?
To translate the mRNA into a protein
