Difference Between Chromosome and Chromatid : Chromosomes and chromatids are important biological structures. They are involved in cell division and DNA replication. Despite their similar-sounding names, they are distinct structures with unique functions. Understanding the difference between the two is crucial, especially so for students of biology and those preparing for PCMB exams.
This comprehensive study material explores the key differences between chromosomes and chromatids. It explains the structure and function of each. The article provides easy-to-understand examples to help grasp the concepts easily. By the end of this article, you'll have a solid understanding of these fundamental biological structures.Related Links -
Chromosomes | Chromatids |
A complete structure made up of DNA and protein | One-half of a replicated chromosome |
It carries genetic information from parents to offspring | It contains a copy of the genetic information present in the parent chromosome |
Visible under a microscope during cell division | Not visible on its own |
Present in pairs in somatic cells and as a single copy in gametes | Present in pairs during cell division and as a single copy in each new cell |
Has a characteristic shape and size | Identical to its paired chromatid |
Passed from one generation to the next during sexual reproduction | Separated during cell division to form new chromosomes |
Can undergo recombination or exchange of genetic information | Cannot undergo recombination or exchange of genetic information |
Can be linear or circular | Can only be linear |
