Don’t start HSC Biology Module 5 without these helpful terms at hand to guide you in the course.

Chromosome

A thread-like structure carrying genetic information in the form of DNA. Humans have 23 pairs of chromosomes – 46 chromosomes in total)Deep Dive Into Mitosis and Meiosis: HSC Biology

Homologous

A pair of maternal and paternal chromosomes. E.g. the maternal and paternal version of chromosome 1.Deep Dive Into Mitosis and Meiosis: HSC Biology

Haploid

Having a single set of unpaired chromosomes (Human haploid cells have 23 chromosomes)Deep Dive Into Mitosis and Meiosis: HSC Biology

Diploid

Having two complete sets of chromosomes, one from each parent (Human diploid cells have 23 pairs of chromosomes)Deep Dive Into Mitosis and Meiosis: HSC Biology

Chromatids

Chromosomes form sister chromatid pairs following replication (as shown in the diagram)Deep Dive Into Mitosis and Meiosis: HSC Biology

Chromatin

The material of which chromosomes are composed of, and will unwind into.

Centrosome

An organelle involved in producing spindle fibres during cell division, made up of a pair of centrioles.

Centriole

Each component of a pair forming the centrosome.

Centriole - Wikipedia

Centromere

The centre of sister chromatids to which spindle fibres attach.

Spindle fibres

Fibres used to attach to the centromere of sister chromatids, which contract to separate each chromatid.Deep Dive Into Mitosis and Meiosis: HSC Biology
