Answer» 1)A chromosome is a string of DNA wrapped around associated proteins that give the connected nucleic acid bases a structure. During INTERPHASE of the cell cycle, the chromosome exists in a loose structure, so proteins can be TRANSLATED from the DNA and the DNA can be replicated.2)MITOCHONDRIA are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in NUTRIENTS, breaks them down, and creates ENERGY rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.3)Cytoplasm, the semifluid substance of a cell that is external to the nuclear membrane and internal to the cellular membrane, sometimes described as the nonnuclear content of protoplasm. In eukaryotes (i.e., cells having a nucleus), the cytoplasm contains all of the organelles.4)nuclei is the small, dense center of the atom. The nucleus is composed of protons and neutrons and has a positive electrical charge. |
