Differentiate between these terms: chromosome, chromatin, and chromatid.

To differentiate: Between chromosomes, chromatin, and chromatid.
Introduction: Chromatin is a complex macromolecule, which contains DNA, protein as well as RNA. Chromosome is a densely packaged chromatin. It is a thread like structure present in nucleus of the cell. A chromosome has a constriction point in the middle called centromere. Chromosomes duplicate during the process of cell division and form sister chromatids, which further gets separted into two chromosomes.
Explanation of Solution
Chromosome, chromatin, and chromatid all occur in the nucleus of the cells, but have some basic differences. The difference between chromosomes, chromatin, and chromatid is shown below:
Criteria | Chromosomes | Chromatin | Chromatid |
Definition | Chromosomes is condensed form of chromatin, which contains DNA and proteins. | Chromatin is very fine interdispersed form of DNA associated with protein and RNA. | The identical pieces of DNA that is held together by acentromere and pulled apart in the cell division process to make new identical cells that are called sister chromatids. |

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forward
