Which one of the following statements is false? DNA methylation in eukaryotes can help inactivate transposons Both histone modifications and DNA methylation can contribute to gene expression differences between different cell types within a person No examples are known of traits passed between generations of organisms that don't involve changes in DNA sequences Histone acetylation is generally associated with active gene transcription DNA methylation in eukaryotes occurs at many of the cytosines present in CpG sequences

Which of the following statements is NOT true? DNA methylation usually inhibits gene expression. Housekeeping genes are unmethylated and active in most cells. A repressor protein would inhibit the ability of TFIID to bind to the TATA box of the promoter. Eukaryotic transcription factors are regulated via covalent modifications, binding of effector molecules, and protein-protein interaction. DNA that contains actively transcribed genes would most likely contain chromatin in the closed configuration. If a portion of a transcription factor's domain is structurally similar in a variety of organisms, it is called a motif.

Select all of the statements that are true regarding DNA methylation and histone methylation: Both are considered epigenetic alterations Both can be passed on to daughter cells through mitosis or meiosis In DNA methylation, a methyl group is added to the base of a nucleotide. In histone methylation, a methyl group is attached to an amino acid Histone methylation can be passed on to daughter cells but DNA methylation cannot be passed on. RNA molecules cause DNA methylation but not histone methylation When a sequence of DNA is methylated, transcription of the associated gene is repressed. When a histone is methylated, transcription could be stimulated or repressed, depending on which amino acids are modified. DNA methylation is permanent while histone modification is temporary RNA molecules can influence both
