Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell’s genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus.
What is the relationship between a chromatin and a chromosome?
Under a special microscope, the chromosomes can look like a continuous string of beads. 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.
What is the relationship among DNA a gene and a chromosome quizlet?
DNA contains the instructions, genes, to make proteins that tell what genetic traits the person will have. The DNA along with the proteins make up the chromosomes. The chromosomes are then passed on to the offspring, and with the DNA inside the chromosomes and translation of the genes, its traits are decided.
What is the relationship between DNA and chromatin quizlet?
Chromatin is the DNA and proteins that make up a chromosome. Chromosomes are the separate pieces of DNA in a cell. And Chromatids are identical pieces of DNA held together by a centromere.
What is the difference between DNA and gene?
In general, a gene is a short section of DNA while DNA- Deoxyribonucleic acid is a molecule. The DNA plays an important role to carry the genetic instructions or the hereditary materials.
Difference Between Gene and DNA.
|A gene is present on a chromosome.||DNA is present within the nucleus of the cell.|
How many genes are in a chromosome?
Chromosome 1 likely contains 2,000 to 2,100 genes that provide instructions for making proteins.
What is the difference between DNA and chromatin?
The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes.
|Difference between Chromosomes and Chromatin|
|Composed of nucleosomes||They are condensed chromatin fibers|
What is the major difference between chromatin and chromosomes?
Chromatin is a complex formed by histones packaging the DNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.
Where does DNA contain its genetic information quizlet?
In human cells, most DNA reside in the nucleus and is divided into chromosomes. long strands of DNA that are closely associated with proteins. sequence of DNA nucleotides that code for a specific protein or RNA molecule. A gene is a sequence of DNA that encodes a specific protein.
