Chromosome and Eukaryotic Chromosome: Difference

The upcoming discussion will update you about the difference between prokaryotic chromosome and eukaryotic chromosome. Difference # Prokaryotic (Bacterial) Chromosome: 1. Structural organization of bacterial chromosome is simple and is represented mainly by double-stranded DNA molecule. Although there are specific proteins associated with bacterial chromosome (not the histories) that help stabilize its supercoiled domains. Compared to eukaryotic chromosome, one can [...]

Difference between Euchromatin and Heterochromatin | Chromosomes

Learn about the difference between Euchromatin and Heterochromatin. Difference # Euchromatin: 1. The chromatin fibres in this region are loosely coiled as compared with hetero­ chromatic regions 2. Euchromatin is deeply stained in divisional cycle but less stained in interphase. 3. The region is genetically active and con­tains unique DNA. 4. Euchromatic regions are able to synthesize mRNA in vitro. [...]

Euploidy: Meaning and Types | Cell Biology

In this article we will discuss about the Meaning and Types of Euploidy. Meaning of Euploidy: Euploldy is the presence of chromosome number which is the multiple of the basic chro­mosome set. An organism with the basic chro­mosome number 7, may have euploids with chromosome number 7, 14, 21, 28, 35, 42. Euploids are further of different types - monoploids, [...]
