Detailed explanation-1: -A double rod of condensed chromatin; contains DNA that carries genetic information. The final stage of the cell cycle, in which the cell’s cytoplasm divides, distributing the organelles into each of the 2 new cells and a new cellular membrane forms around each new cell.
Detailed explanation-2: -chromosome – A double rod of condensed chromatin.
Detailed explanation-3: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Detailed explanation-4: -Chromosomes are condensed chromatin that contains genetic information that is passed onto offspring. The nucleolus makes ribosomes inside the nucleus, where proteins are assembled according to the DNA directions. The ribosomes use instructions from the nucleus to build proteins.
Detailed explanation-5: -Chromatin in the nucleus condenses to form double-rod structures called chromosomes. Looks like an “X”. Each chromosome has two rods because the cell’s DNA has replicated, and each rod in a chromosome is an exact copy of the other.
