In this article we will discuss about:- 1. Meaning of Chromosomes 2. Chromosome Number 3. General Morphology. Meaning of Chromosomes: In 1875, Strasburger discovered thread-like structures which appeared during cell division. Later, these structures were termed as chromosomes (chroma = colour; soma = body) by Waldeyer in 1888 since they showed affinity for basic dyes and could be stained deeply, [...]
The following points highlight the two main adaptational forms of chromosomes. The forms are: 1. Polytene Giant Chromosomes 2. Lampbrush Chromosomes. Form # 1. Polytene Giant Chromosomes: Polytene giant chromosomes are normal interphase chromosomes where homologues become paired and undergo several replications; all the copies so produced remain associated together. Polytene giant chromosomes are typically found in salivary gland cells [...]
