What is the difference between chromosomes and chromatin quizlet?

What is the difference between chromosomes and chromatin and chromatid?

Chromosomes are single-stranded groupings of condensed chromatin. … A duplicated chromosome is double-stranded and has the familiar X shape. The two strands are identical and connected at a central region called the centromere. A chromatid is either of the two strands of a replicated chromosome.

What is the relationship between chromosomes 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.

What is the difference between chromosome and chromatin Class 9?

Answer: Chromatin is the DNA fibers which are scattered all over inside the nucleus in the interphase of mitosis. Whereas chromosome is a highly condensed chromatin or DNA fiber which is seen just prior to a cell division, be it mitosis or meiosis.

What is the difference between a chromatid and a chromosome in anaphase?

The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere. During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.

What is chromatin quizlet?

Chromatin. An organelle which forms chromosomes during cell division. Consists of DNA, RNA, and proteins. This organelle can have different structures (e.g.an “x” or lines spinning). This organelle is only found in a eukaryote cell.

Are chromosomes chromatin?

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. During cell division, the structure of the chromatin and chromosomes are visible under a light microscope, and they change in shape as the DNA is duplicated and separated into two cells. …

What is the relationship between chromatin and chromosomes in mitosis?

The cellular DNA is replicated during interphase, resulting in the formation of two copies of each chromosome prior to the beginning of mitosis. As the cell enters mitosis, chromatin condensation leads to the formation of metaphase chromosomes consisting of two identical sister chromatids.
