True/False: Do Sp1 and Sp3 bind to the DRG2 promoter and decrease expression?
Above statement is false why because SP1 and SP3 directly bind to the ABCG2 promotor region and increase this promoter activity.
ABCG2 is a member of the ATP binding cassette trans membrane proteins.
True/False: Do Sp1 and Sp3 bind to the DRG2 promoter and decrease expression?
A cell is found to have a high degree of methylation on the promoter for the Rb gene. True or False: This methylation pattern will impact protein primary sequence. True False A cell is found to have a high degree of methylation on the promoter for the Rb gene. Would this methylation pattern impact gene expression? (select one best answer) Transcription would increase Translation would increase No change in expression would occur Transcription would decrease
Some mutations occur in the promoter of Msh2 and decrease its expression relative to wild-type cells leading to cancer. Would you confirm this pattern using DNA sequence or RNA sequence and why?
Promoters are cis-acting. The promoter is considered a cis-acting site because: A it influences the expression of a family of genes within a protein domain. B it exclusively influences the expression of genes to which the promoter is proximal. C it activates the gene it is proximal to while inhibiting the expression of all others. D it regulates the transcription of both alleles of an allele pair. E promoters bind to the sigma subunit.
True or False; One molecule of IgG may bind to many different types of antigens. True O False

QUESTION 9 Regulation of gene expression by eukaryotes is more complicated that in prokaryotes. The promoter region contains proximal regulatory sequences that are called _regulatory elements. These proximal regulatory elements bind trans-acting proteins that are called __factors.

True or false: A helper T-cell can directly recognize and bind to antigens on the surface of pathogens. If false, make it a correct statement.
2. To begin transcribing a gene, RNA polymerase has to find and bind to the promoter region. What class of protein co-factors help RNAP do this? (Bonus: what is the term for an RNAP enzyme complexed with one of these?) 3. Name two antibioties that target bacterial ribosomes and describe how they work (Bonus if you do more than two). ABOS
What do source and sink mean in unregulated gene expression?
OM op promoter (A) mRNA (M) protein (P)
