are chromatin and chromosomes the same thing?

The main difference between chromatin and chromosome is that chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material between ...

In eukaryotes, however, genetic material is housed in the nucleus and tightly packaged into linear chromosomes. Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.

A replicated chromosome (or equivalently, a duplicated chromosome) contains two identical chromatids, also called sister chromatids. The difference between a duplicated chromosome and a chromatid, strictly speaking, is that a chromosome contains two chromatids that are joined at a structure called a centromere.

As nouns the difference between chromatin and nucleoplasm is that chromatin is (biology) a complex of dna, rna and proteins within the cell nucleus out of which chromosomes condense during cell division while nucleoplasm is the protoplasm of a cell nucleus.

B. How does the structure of chromosomes differ in prokaryotes and eukaryotes? Prokaryotic chromosomes are composed of a single, circular strand of DNA. Eukaryotic chromosomes are made up of DNA that is tightly wound around histone molecules.

DNA is packaged into tightly wound structures called chromosomes. ... Each long string of DNA winds around structural protein spools called 'histones' to form a material called 'chromatin'. The chromatin further loops and coils to form the tightly condensed chromosome structure.

Chromatin, Chromosomes and Chromatids The chromatin undergoes further condensation to form the chromosome. So the chromatin is a lower order of DNA organization, while chromosomes are the higher order of DNA organization. Chromosomes are single-stranded groupings of condensed chromatin.

Sister chromatids are two identical copies of the same chromosome formed by DNA replication, attached to each other by a structure called the centromere. During cell division, they are separated from each other, and each daughter cell receives one copy of the chromosome.

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. ... Chromatin exists in two forms. One form, called euchromatin, is less condensed and can be transcribed. The second form, called heterochromatin, is highly condensed and is typically not transcribed.

The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes. This means chromatin is lower order of DNA organization whereas chromosomes are higher order of DNA organization.

What is the difference between a chromatid and a chromosome? See Section 12.1 ( page 255) . 1) A chromatid is one half of a replicated chromosome, whereas a chromosome consists of DNA wrapped around proteins in a highly organized manner.

Chromosomes contain tightly packed DNA molecules while in case of chromatids, the DNA molecules are unwound. A chromosome is made up of a single, double-stranded DNA molecule while a chromatid comprises of two DNA strands joining collectively by their centromere. The chromatids contain a substance called chromatin.

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.

In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. ... DNA and histone proteins are packaged into structures called chromosomes.

Chromatin is a substance located in the nucleus of plant and animal cells consisting of RNA, DNA and other proteins. Chromatin is only present in cells containing a nucleus. The exact structure and function of chromatin mainly depends upon the phase of the cell cycle.

A chromosome is an organized package of DNA found in the nucleus of the cell. Different organisms have different numbers of chromosomes. Humans have 23 pairs of chromosomes--22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y.

Genes and Chromosomes. Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
