Module 7; Part 2

Genes in bacteria are called ________

In bacteria, transcription produces a large _____________ ____ that encodes more than one protein

• polycistronic mRNA

• polycistronic rRNA

• monocistronic mRNA

• monocistronic rRNA

Eukaryotes have _____________ ____ meaning that each mRNA encodes for a single protein product

• polycistronic mRNA

• polycistronic rRNA

• monocistronic mRNA

• monocistronic rRNA

Where does transcription occur for eukaryotes?

Where does transcription occur for prokaryotes?

Can mRNA stay in a eukaryotic nucleus for translation?

• No, it must leave the nucleus and enter the cytoplasm for translation.

• Yes, it can translate within the nucleus.

• It depends on the type of organism; some eukaryotes allow transcription in the nucleus, and some do not.

• Yes, it can translate within the nucleus but still needs to eventually leave the nucleus to be turned into polypeptide chains.

Chromatin must uncoil to make DNA accessible to RNA polymerase.

• Free Chromatin

• Chromatin condensation

• Chromatin demolition

• Chromatin remodeling

RNA polymerases rely on _____________ _______ to scan/bind DNA

Select all that is true: These control transcription regulation.

• Enhancer mutations

• Silencers

• Chromatin structure

• Methylated Cytosines

Select all that is true: #1

• rRNA

• mRNA

• snRNA

• 5S rRNA

• tRNA
