Define heterochromatin and euchromatin. Name one structure within a chromosome where you would find a lot of heterochromatin. What is the difference between the level of expression of genes that are localized to heterochromatin compared to euchromatin?
Pronoy S.
Gene A, which is normally expressed, has been moved by near an area of heterochromatin. None of the daughter cells produced after this recombination event express gene A, even though its DNA sequence is unchanged. Explain what happened.
