Webcentromere, structure in a chromosome that holds together the two chromatids (the daughter strands of a replicated chromosome). The centromere is the point of attachment of the kinetochore, a structure to which the microtubules of the mitotic spindle become anchored.

WebWhat is Chromatin? Chromatin is a complex of RNA DNA and protein that may be seen in eukaryotic cells.Its high characteristic is packaging very lengthy DNA molecules into a denser form, compact which stops the strands from becoming tangled and performs essential roles in strengthening the DNA during cell department, heading off DNA damage, … WebAug 2, 2024 · Chromatin is a combination of DNA and histone proteins that form the chromosomes in eukaryotic cells. Chromatin can be found throughout the cell but does not always have to be visible or spread out. Chromosomes are made from long strands of chromatin coiled up into a bundle called a nucleosome. The function of chromatin is to …

WebØ The Folded Fibre Model of chromosome was proposed by DuPraw in 1965. Ø He published this model based on his studies on human chromosomes using electron microscope. Ø The important features of Folded Fibre Model of Chromosome are: @. Each chromosome contains a single but long and coiled chromatin fibre.
WebA chromatid is a condensed DNA subunit of a chromosome. The two chromatids of a duplicated chromosome are held together at a region of DNA called the centromere (see figure below). Centromeres are the attachment points for microtubules, which are responsible for the guiding the movement of chromosomes during mitosis and meiosis.
Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division, preventing DNA damage, and regulating gene expression and DNA replication.
