it is termed a chromatid. When a cell undergoes cell division, chromosomes go ahead and replicate. In this process, two chromatids are formed and they are joined together through a structure called- centromere. The formation of chromatids from the chromosome usually occurs during S-phase in cel...
What is the difference between chromatin and chromatid? Chromosomes: A chromosome is a structure in the nucleus tightly packaged with DNA. The DNA is supported by histones around which it is coiled. The chromosomes are vital in ensuring that the replication and distribution of DNA in the cell ...
Explain the difference between chromatins and chromatids, and what part of the DNA each of them make up? What role do they have in the structure of DNA?Answer and Explanation: Chromatin is spread out within the nucleus of...
Explain the difference between chromatins and chromatids, and what part of the DNA each of them make up? What role do they have in the structure of DNA? Explain the differences between meiosis and mitosis. Do basophils become mast cells when they leave the circulation and enter...
Telophase is the final phase of mitosis, and this is when the official division of one cell into two happens. First, the chromosomes relax back into chromatin and a nuclear envelope forms around each chromatin blob, making it into a brand new nucleus. A nucleolus appears in each of these ...

Changes to the epigenome can result in changes to the structure of chromatin and changes to the function of the genome. Genome The total genetic content contained in a haploid set of chromosomes in eukaryotes, in a single chromosome in bacteria or archaea, or in the DNA or RNA of viruses....
Mitosis:During the first mitotic stage, known as prophase,chromatincondenses into discrete chromosomes, the nuclear envelope breaks down, andspindle fibersform at opposite poles of the cell. A cell spends less time in prophase of mitosis than a cell in prophase I of meiosis. ...

the chromatin packages the dna into a small unit such that it fits into the nucleus. it also protects the dna structure and sequence. it controls gene expression and replication and prevents chromosome breakage. q5 what is the difference between cytoplasm and nucleoplasm? the cytoplasm is found ...
