_____, like the material in centromeres, contains non expressed genes
A. euchromatin < my answer
B. Neither of these is correct
C. Heterochromatin
D. Both of these are correct
Heterochromatic regions are tightly packed and transcriptonly inactive. Telomere and centromere are example of Heterochromatin
Option C is corect.

Question 12 0.5 pts Centromeres are considered to be: Heterochromatin Euchromatin ORNA Unpaired nucleosides Unpaired nucleotides Question 13 0.5 pts The human karyotype: Is ordered according to the size of the chromosomes. Consists of both prokaryotic (mitochondrial) DNA and eukaryotic (nuclear) DNA. Excludes the sex chromosomes, X and Y. Can show how frequently certain genes are expressed within the animal. Differs from the animal's total chromosomal count in the animal by including the X and Y chromosomes. Question...
In eukaryotic genomes, regions of _____________________ are transcriptionally active while regions of ____________________ are transcriptionally silent. A) Heterochromatin; euchromatin B) Euchromatin; heterochromatin C) None of the above Which of the following proteins can regulate eukaryotic gene expression WITHOUT binding to the DNA in the regulatory region?

You have developed an activator of a non-receptor tyrosine kinase. In three different cell types that all contain this receptor your drug has different effects. In cell type A you see activation of gene X and gene Y; in cell type B you note activation of Gene X, but no change in the mRNA levels for Gene Y. In cell type C your drug has no effect on either Gene X or Y. Describe how could each choice (A-D) be...
