Topic 8 Transcription & Transcriptional Regulation - Eukaryotes Flashcards
In the beads-on-string model of Eukaryotic chromatin, what is the string and what are the components of the beads?
The string is the DNA wrapping that links the beads called nucleosomes. These are made of protein and DNA
Describe the basic structure of nucleosome.
What is a “TATA box”?
What is the function of TFSll in RNA polymerase ll transcription.
Which enzymes are responsible for synthesis of ribosomal RNAs in human cells.
Which complex is responsible for transforming the closed preinitiation complex of Pol ll into open preinitiation complex?
Which enzyme is responsible for synthesis of pre-rRNA in human cells?
Where are the N terminal tails of the histones?
What does dynamically regulated mean?
What happens during replication in the S phase?
What domains does the interphase chromatin have?
Which complex is responsible for transforming the closed preinitiation complex of Pol ll into open preinitiation complex?
Which enzyme is responsible for synthesis of pre-rRNA in human cells?
Name a role of the nucleolus Polymerases l and lll.
Name a benefit of packing nuclear genomic DNA into Chromatin with his tones in eukaryotes.
