Replication and Distribution of DNA during Mitosis Figure 1: During prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures.

What are the differences between chromosomes, chromatids and chromatin? In the nucleus, the DNA double helix is packaged by special proteins (histones) to form a complex called chromatin. The chromatin undergoes further condensation to form the chromosome. So while the chromatin is a lower order of DNA organization, chromosomes are the higher order of DNA organization.

- Prophase (from the Greek πρό, before and φάσις, stage), is a stage of mitosis in which the chromatin condenses into double rod-shaped structures called chromosomes in which the chromatin becomes visible. This process, called chromatin condensation, is involved with the condensin complex.

The Cell Cycle, Mitosis and Meiosis Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides. 1  G1 phase.he homologous chromosomes pair and exchange DNA to form recombinant chromosomes. Prophase I is divided into five phases: 1  Leptotene: chromosomes start to condense. 2  Zygotene: homologous chromosomes become closely associated (synapsis) to form pairs of chromosomes (bivalents) consisting of four chromatids (tetrads).

cell cycle Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

Replication and Distribution of DNA during Meiosis Meiosis I consists of four phases: prophase I, metaphase I, anaphase I, and telophase I. Figure 1: Recombination is the exchange of genetic material between homologous chromosomes. During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere.

- On the other hand, chromatin is a mass of genetic material containing DNA, RNA, and various proteins that forms chromosomes. **before mitosis, the DNA is loose in the nucleus in the form of chromatin. When the DNA begins to undergo mitosis the chromatin condenses to form the chromosome.The difference between chromatin and chromosomes is that chromosomes help to make up chromatin.Chromatin is made up of DNA and proteins, and is what makes the nucleus of a cell. Chromosomes make up the DNA.he difference between chromatin and chromosomes is that chromosomes help to make up chromatin.

In what phase do chromosomes move to opposite poles? At metaphase the chromosomes line up along the middle of the cell. At anaphase the chromosomes begin to move and go to opposite ends of the cell due to the action of spindle fibres. Then at telophase the chromosomes are actually at individual sides of the cell and the spindle fibres break down. So, during Anaphase.

Chromosomes During interphase, the cell's DNA is not condensed and is loosely distributed. A stain for heterochromatin (which indicates the position of chromosomes) shows this broad distribution of chromatin in a mouse cell (upper left). The same stain also shows the organized, aligned structure of the chromosomes during mitosis.uring interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible.

Mitosis These stages are prophase, prometaphase, metaphase, anaphase, and telophase. During mitosis, the chromosomes, which have already duplicated, condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell. The result is two genetically identical daughter nuclei. The rest of the cell may then continue to divide by cytokinesis to produce two daughter cells.

Biology for Kids When a cell gets the signal that it is to duplicate, it will enter the first state of mitosis called the prophase. 1  Prophase - During this phase the chromatin condenses into chromosomes and the nuclear membrane and nucleolus break down. 2  Metaphase - During metaphase the chromosomes line up along the middle of the cell.

- Answer by Ligand. Confidence votes 7.7K. Chromosomes are easiest to see when they are condensed (coiled and supercoiled, so that they become short and fat). They are at their most condensed from late prophase through to early telophase, in either mitosis or meiosis.he tetrad is a structure that only exists during the late stages of Prophase I and early stages of Metaphase I in Mieosis I. Prior to being sent off to different cells, the h … omologous chromosomes clump together in these units called tetrads consisting of 2 chromosomes and 4 chromatids.

- The chromosomes uncoil, and the cell matures during G1 phase of interphase. Many people believe that DNA and/or Chromosomes (Chromosomes are made of DNA, remember.) are only present during mitosis. They just get fatter during mitosis by coiling tighter. Thus they are more easily seen.

During what stage of the cell cycle is Chromatin found? · just now. 1  Chromatin is always there, in the nucleus. 2  I know because I have my anatomy book right in front of me, but Chromatin is only found during interphase which is before mitosis actually begins, or during telophase, the last phase where the chromosomes unwind to become the chromatin fibers once again.

How do chromosomes form from chromatin? CHROMOSOMES Chromosomes become evident as discrete structures only during cell division, whether mitosis or meiosis. In both processes the chromatin strands replicate to form two identical strands and then coil up or condense to form chromosomes. Each chromosome is thus a duplicate structure consisting of two chromatids attached to one another at the centromere.
