During which phase does the dna make a copy of itself?

Because of this, DNA makes a copy of itself in a process known as replication during interphase, a stage that occurs before cells divide. the answer is interphase hopes this helps.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
