In contrast, the genomes of eukaryotes are composed of multiple chromosomes, each containing a linear molecule of DNA. Although the numbers and sizes of chromosomes vary considerably between different species (Table 4.
2), their basic structure is the same in all eukaryotes. 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. The chromosomes contains 13 DNA and the rest of 23 is formed from histones and nonhistones proteins.
There exists two types of chromatin Feb 26, 2012 Best Answer: 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. CHAPTER 7 COMPARE AND CONTRAST. STUDY. PLAY. prokaryotic vs. eukaryotic. Prokaryotic chromatin chromosomes chromatin in the undividng cells, uncoiled stringy DNA Chromosomes in the dividing cell, coiled into colored bodies" and wrapped in protein 46 in humans.
Chromatin and chromosomes are both structures of DNA, but chromosomes are condensed chromatin. DNA exists as chromatin a majority of the time so that the DNA is accessible to proteins for transcription and proteins can be made during the process of Chromatin is the DNA and proteins that make up chromosomes.
Chromosomes are the separate 'pieces' of DNA in a cell (made up of chromatin ). Sister chromatids are identical pieces of DNA held together by a centromere and pulled apart during cell division to make new identical chromosomes in the newly made cells.
Start studying Bio test: protein synthesis and dna. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Difference between heterochromatin and euchromatin Heterochromatin is a part of chromosome, a tightly packed form of DNA whereas euchromatin is an uncoiled form of chromatin.
Heterochromatin has tighter DNA packing than euchromatin. The key difference between chromosome and chromatid is that a chromosome is a long threadlike form of a DNA molecule while a chromatid is onehalf of two identical copies of a replicated chromosome.
In fact, two chromatids are joined together by a centromere to form a chromosome. Chromosome and chromatid are closely related
