Y-linked
With respect to mitochondrial inheritance, which, if any, of the following statements is
false?
,Affected individuals can be of either sex.
Mitochondrial disorders are transmitted virtually exclusively through the maternal line.
Both the sperm and the egg contribute mitochondrial DNA to the zygote, however,
the paternal mtDNA is destroyed in the early embryo.
Clinical variability is a common feature of mitochondrial DNA disorders.

Hemophilia A
Sickle cell animia
Amyotrophic lateral sclerosis

Steroid 21-hydroxylase deficiency
part of networks that regulate all aspects of DNA metabolism, including transcription,
replication, and recombination
Required to bring a distant enhancer in close proximity to the promoter of the gene it
regulates

DNA looping
,Treating disease by removing an environmental trigger
Ex: metabolic disorders can be helped by taking away certain foods

Treatment by altering disease susceptibility
With respect to histone modifications, which, if any, of the following statements, is
true?
histone acetylation always means adding an acetyl group to the side chain of a lysine
residue.
in histone acetylation each lysine of the histone is acetylated.
in histone phosphorylation a phosphate group is transferred to the side chain of a
serine .
in histone methylation it is the DNA that coils around a nucleosome that is methylated,
not the histone itself.

evolution, and therefore have low copy repeats
