- Arrange the levels of chromatin packing from most "open" to most condensed (chromosome, loops, nucleosomes, heterochromatin, 30-nm chromatin fiber)Why is transcriptionally active chromatin ∼10 times more susceptible to cleavage by DNase I than transcriptionally silent chromatin?Modifications of histone tails can: O repress the transcription of some genes affect chromatin structure affect the transcription of some genes in response to the diet or environment activate the transcription of some genes all of these choices are correct The ferritin gene encodes an IRE (Iron-response element) within the 5 UTR (untranslated region) of the MRNA Considering what you know about eukaryotic translation, the IRE-BP (Iron Response Element Binding Protein) is bound to the IRE in the 5'UTR. you would expect: O That the presence of the IRE-BP would enhance translation. That the presence of the IRE-BP would have no effect. That the presence of the IRE-BP would block translation I don't remember enough about the IRE-BP or transiation to guess. 3 Assuming that the trait represented by the filled symbols in the pedigree is an inherited trait due to a single gene with alleles A and a, what mode of inheritance does the pedigree shown suggest?
