Transcription

Where does transcription occur in a cell?

• ribosome

• nucleus

• cytoplasm

• golgi apparatus

What is the function of the Cap and Poly A Tail?

• To decrease the length of the molecule

• To allow an exit from the nucleus

• Serves as a signal

• Protection from enzymes

What are expressed as proteins?

• Exons

• Introns

• RNA polymerase

• Promoters

What is the job of RNA polymerase?

• Splicing

• To unzip the DNA molecule

• Make a complementary RNA molecule

• Protect the DNA

What does RNA polymerase bind to that helps show it where to start?

• Enhancers

• Promoters

• Introns

• Exons

What nucleotides are in RNA?

• A, T, C, G

• Only Uracil

• A, T, U, C, G

• A, U, C, G

What are three base sequences that code for a single amino acid?

• Codons

• Promoters

• Exons

• Introns

What would the complementary mRNA strand be if the DNA strand is GTA CTA?

• CAU GAU

• CTA GAT

• CTT GAA

• CAT GAT

Which of the following is a START codon?

• UGG

• UGA

• AUG

• UAA

What is done with the portion of DNA that does NOT code for proteins?

• Introns are spliced out.

• They are kept in the coding sequence.

• Exons are spliced out.

• Nothing happens.
