What are the differences between chromatin and chromosomes?

Answer 1

Chromatin and chromosomes are basically the same thing. The difference is that chromatin is unfolded, uncondensed, extended DNA while chromosomes are condensed DNA. Chromosomes are condensed chromatin and chromatin is unfolded chromosomes.

The only difference I know is that chromatin are present normally in a cell, while chromosomes are there only when the cell is about to divide. When the cell is about to divide, the chromatin threads get organised into chromosomes.

Utilizing their histone proteins to accomplish this, DNA first condenses into 10 nm strands and then into 30 nm strands, ready for Condensation and then Cytokinesis.

Answer 2

When the chromosome is duplicated it's called sister chromatids, and so each one of them is called a chromatid. At times it seems people will still call sister chromatids as "chromosomes", it's just more accurate to use "sister chromatids".

Answer 3

Chromatin is DNA wrapped around a sequence of histone proteins (nuleosomes) to allow full strands of DNA to fit inside nucleus. At the beginning of cell division The histone proteins condense and join together to form a chromatid a copy of DNA also known as a chromosome. Sometimes one chromatid is present in a chromosone however prior to cell division this copy of DNA is duplicated to create a chromosone with two chromatids.

Answer 4

Chromatin is a complex of DNA and proteins found in the nucleus of a cell, while chromosomes are condensed and visible structures formed by chromatin during cell division. Chromatin contains DNA tightly wrapped around histone proteins, while chromosomes are the highly organized and condensed structures that contain genetic material.

Answer 5

Chromatin is DNA wrapped around a sequence of histone proteins (nucleosomes) to allow full strands of DNA to fit inside the nucleus. At the beginning of cell division the histone proteins condense and join together to form a chromatid, a copy package of DNA also known as a 30 nm fiber.

Sometimes one chromatid is present in a chromosone however prior to cell division this copy of DNA is duplicated to create a chromosone with two chromatids.
Hi,

Basically, a chromosome is two chromatids joined together at the centromere, and the two chromatids on a chromosome are identical. Normally, the cell only needs one copy of each set of genetic material so chromatids are enough, but because the genetic information of the cell will be distributed to two daughter cells during mitosis/meiosis the chromatids must be doubled. This is achieved in the S-Phase of a cell cycle. With two copies of each allele, the genetic information will be evenly distributed and will be the same between the two sister cells.

Hope this helps

Answer 6

A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere. They are known as sister chromatids. Once the paired sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.

Answer 7

Chromatid are the two "sister" sides of a chromosome that are identical to each other and contain the same genetic information. The chromosomes split in half during mitosis (or meiosis in sex cells) and each new daughter cell gets one chromatid.

Answer 8

chromatin is in the nucleus of the cell and is the stuff thats visible during the stages where the cell is not dividing. There are two types of chromatin - euchromatin and heterochromatin, heterochromatin is slightly denser, inactive DNA whereas euchromatin is active less dense DNA. A chromosome is made up of sections called genes and and is responsibe for certain characteristics of a human. A chromatid is half of one chromosome. Both chromatids and chromosomes are only visible during cell division where they line up at the equator of the cell.

Answer 9

A sister chromatid is one of the pair of a duplicated chromosome joined in the center by a centromere. Google mitosis.

Answer 10

Chromosome need 2 chromatids but a chromatid is only half of a chromosome
