RNA Review

The Central dogma of molecular biology is

• RNA----DNA-----Protein
• DNA----Protein----RNA
• Protein----RNA---DNA
• RNA----Protein-----DNA
• DNA---RNA----Prrotein

Which of the following are found in both DNA and RNA?

• ribose, phosphate groups, and adenine
• deoxyribose, phosphate groups, and guanine
• phosphate groups, guanine, and cytosine
• phosphate groups, guanine, and thymine
• cytosine, thymine, and guanine

The types of RNA in the cell that we studied in this class are

• tRNA/gRNA/cRNA
• rRNA/mRNA/tRNA
• gRNA/pRNA/rRNA
• cRNA/rRNA/pRNA

This is sliced out of pre-mRNA before it leaves the nucleus.

• Introns
• Exons
• Proton
• Neutrons

The process by which the genetic code of DNA is copied into a strand of RNA is called

• translation
• transcription
• transformation
• transaction
• none of these are correct
