In mitosis, the chromatin condenses to form chromosomes during prophase.
Answer:
A. The two alleles for each gene separate as homologous chromosomes move apart during anaphase I.
Explanation:
Took it in Biology
It is actually Covalent bonds. I just took the same question for my science quiz.
While genetics corresponds to the study of genes, epigenetics is interested in a "layer" of complementary information that defines how these genes will be used by a cell ... or not.
In other words, epigenetics is the study of changes in gene activity, does not involve modification of the DNA sequence and can be transmitted during cell divisions. Unlike mutations that affect the DNA sequence, epigenetic changes are made on the proteins surrounding the DNA and are reversible.
So the right answer is the proteins around which dna is wrapped
