The inheritance of gene expression patterns, in the absence of the initiating signal, is called Epigenetic regulation.
Epigenetic changes can be defined as inherited variations which are not present in the DNA sequence. Gene expression is regulated at different levels and not merely in response to DNA modifications. Examples of epigenetic control include DNA methylation, histone deacetylation and mi-RNA expression.
Epigenetic mechanisms add an adaptive layer of control in the regulation of gene expression that allows an organism to adapt to a dynamic environment.
Epigenetic regulation increases the functional intricacy of deoxyribonucleic acid (DNA) by changing chromatin structure, nuclear organization as well as transcript stability.

The DNA has to replicate before mitosis to keep the number of chromosomes consistent. Hope this helps.
Translation of mRNA into a peptide occurs in sequences of 3 nucleotides called codons. Each codon codes for one amino acid. Therefore, as the ribosome reads the codon sequence, it recruits a t-RNA carrying the respective amino acid. A peptide bond is thereafter formed on the growing amino acid chain before the ribosome translocates to read the next codon. This continues until the ribosome reads a stop codon signaling the end of the peptide.
The basic needs of all cells in the body is to have food, oxygen, and have their wastes taken away.
The processes is an example of hydrolysis is conversion of cellulose into glucose units. The answer is letter C. Conversion of glucose units into starch and conversion of fructose and glucose units to form <span>sucrose are not processes of hydrolysis.</span>
