THE MITOTIC
CELL CYCLE
, STRUCTURE OF A CHROMOSOME
A chromosome is a thread-like structure composed of DNA and
associated histone proteins, that carries genetic information. Here's
a breakdown of the components:
• DNA (Deoxyribonucleic Acid): carries genetic information in the
form of genes.
• Histone Proteins: around which the DNA is coiled to form a
structure called chromatin. This helps to package the DNA and
manage its structure.
• Sister Chromatids: After DNA replication, each chromosome
consists of two identical halves, called sister chromatids, joined
by a centromere.
• Centromere: The region where the two sister chromatids are
joined together. It's crucial during mitosis for the proper
