Bacterial Chromosome | Definition, Structure & Function

Minute to Understanding: What is a chromosome?

Suppose you have a line of mice that has cytologically distinct forms of chromosome 4 . The tip of the chromosome can have a knob (called 4^K ) or a satellite (4^S) or neither (4). Here are sketches of the three types: You cross a 4^K / 4^S female with a 4 / 4 male and find that most of the progeny are 4^K / 4 or 4^S / 4, as expected. However, you occasionally find some rare types as follows (all other chromosomes are normal): a. 4^K / 4^K / 4 b. 4^K / 4^S / 4 c. 4^K | Numerade
