These protein-chromosome complexes are called chromatin.
WebThese two regions are A) called heterochromatin and euchromatin B) uniform in the genetic information they contain C) separated by large stretches of repetitive DNA D) each void of typical protein-coding sequences of DNA E) void of introns 26) Chromatin of eukaryotes is organized into repeating interactions with protein octamers called nucleosomes. WebThe DNA in eukaryotic cells is organized into structures called chromosomes. In humans, there are 23 pairs of chromosomes or 46 chromosomes in total. These chromosomes are highly compacted to give this structure, and they contain a lot of DNA. The human genome (haploid) is about 3 billion nucleotides long.
WebEach chromosome consists of one continuous thread-like molecule of DNA coiled tightly around proteins, and contains a portion of the 6,400,000,000 basepairs (DNA building blocks) that make up your DNA. The way DNA is packaged into chromatin is a factor in how protein production is controlled. Duration: 1 minutes, 30 seconds. WebMar 5, 2024 · The DNA in the bacterial chromosome is arranged in several supercoiled domains. As with eukaryotes, topoisomerases are involved in supercoiling DNA. DNA gyrase is a type of topoisomerase, found in bacteria and some archaea, that helps prevent the overwinding of DNA. (Some antibiotics kill bacteria by targeting DNA gyrase.)
