    1. trans-acting factors are able to regulate target genes from any chromosome, whereas cis-acting elements can only regulate genes located in the same chromosome. a. True only in operons. In Eukaryotic systems, trans-acting factors only regulate genes in the same chromosome. b. True only in Eukaryotes. Prokaryotes don’t have cis-acting elements. c. True for any organism. d. False. The statement is erroneous 2. Unlike activators, repressors never affect chromatin structure. Repressors inhibit transcription only by binding to the binding sites...

    AS Part A Which of the following events occurs during DNA replication? All methylation of the DNA is lost at the first round of replication Methylated DNA is copied in the cytoplasm, and unmethylated DNA is copied in the nucleus Methylation of the DNA is maintained because DNA polymerase directly incorporates methylated nucleotides into the new strand opposite any methylated nucleotides in the template. Methylation of the DNA is maintained because methylation enzymes act at DNA sites where ane strand...

    Part 1. Eukaryotes use at least two distinct mechanisms to control gene expression by altering the structure of chromatin around a particular gene. One of these mechanisms is the covalent modification of histones to switch DNA between an open and closed confirmation. A second mechanism is the covalent modification of DNA (typically on cytosines) by methylation. A. Describe a type of histone modification and explain what effect is has on chromatin, and how that effect is achieved. a. One type...

    What are SOS gene products? How are they induced? A. SOS proteins (RecA, SSB, uvrABC, etc); nicked DNA binds to the Lac repressor, causing its release and degradation, thereby triggering expression of the SOS genes B. SOS proteins are the heat-shock proteins; the “chi” sequence binds to some transcription factors inducing expression of these genes C. SOS proteins are only transcription factors that activate other genes; DNA damage causes induction of these transcription factors through single-stranded DNA binding proteins D....

    Which of the following mechanisms to regulate gene expression are observed in eukaryotes, but are not generally observed in prokaryotes? Choose all that apply. Genes are grouped into operons, which allows transcriptional regulation to turn them all on together. RNA silencing selectively targets mRNA and destroys it to prevent further translation. Proteins can be activated or deactivated as a form of post-translational regulation. Epigenetic regulation can open or condense sectiosn of a chromosome, regulating which genes are transcribed. Regulatory proteins...
