Summary Introduction
To explain: A chromosome.
Introduction: Nucleus is the largest organelle of the cell. It contains chromosomes that are a thread-like structure and carry genetic information in the form of the gene.
Summary Introduction
To distinguish: A haploid cell and a diploid cell.
Introduction: A chromosome is a thread-like structure made up of deoxyribonucleic acid (DNA). It is tightly packed in the nucleus of a cell. Humans normally have 23 pairs of chromosomes.
