p53 Function: Pro cell cycle arrest and pro cellular apoptosis. HIF Function: Protection of hypoxic cells from cellular apoptosis NF-kB Function: Role in immunity, cell apoptosis, inflamatory response and cell survival. c-myc Function: It is a proto oncogene (understand the characteristics of proto - oncogenes) FOS Function: Role in signalling and cell survival In case of any querry feel free to ask Dr. Rajan Gogna Jawaharlal Nehru University

Can eukaryotic Cells control gene expression by using transcription factors?
yes
Why does chromatin remodeling have to be the first step in gene activation?
Eukaryotic DNA can be highly packaged in condensed chromatin and inaccessible to transcription factors and RNA polymerase.
Where are transcription factors made?
Some transcription factors are proteinacious , they are synthesized in ribosomes .
What has the author Kenneth Maiese written?
Kenneth Maiese has written: 'Forkhead transcription factors' -- subject(s): Forkhead transcription factors, Forkhead Transcription Factors, Physiology
Which is true about eukaryotic gene regulation?
Most eukaryotic genes are controlled individually and have regulatory sequences that are much more complex than those of the lac operon. (this answer above was found in my Biology text book too so it is correct) :)
What are the 7 classes of protein based on function?
kinases, enzymes, peptidases, antibodies, ribosomal proteins, transcription factors, ion channels
How does a Tata box helps position rna polymerase. In a eukaryotic cell?
The TATA box seems to help position RNA polymerase by marking a point just before the point at which transcription begins.
What can inhibit transcription by blocking the binding of positively acting transcription factors to the DNA?
repressor
During protein synthesis in eukaryotic cells does the activator-enhancer complex the molocule of DNA so other transcription factors have better acces tothe bonding sites on the operator?
Yes. If I understand your question correctly (I cleaned up the wording slightly). Activators are proteins that bind to enhancer regions of DNA. This facilitates the binding of transcription factors and the RNA Polymerase to read the DNA of the gene.
What kind of organisms use transcription factors?
Eukaryotes
Which is true of transcription factors?
They control which genes are expressed.
What is the function of the nuclear envolope?
The nuclear envelope is a double lipid layer that encloses the genetic material in eukaryotic cells. The nuclear envelope also serves as the physical barrier, separating the contents of the nucleus (DNA in particular) from the cytoplasm. Many nuclear pores are inserted in the nuclear envelope, which facilitate and regulate the exchange of materials (proteins such as transcription factors, and RNA) between the nucleus and the cytoplasm
