What best describes the eukaryotic chromosome?
Eukaryotic chromosomes consist of DNA tightly wound around clusters of histone proteins. In general, eukaryotic cells contain a lot more genetic material than prokaryotic cells. For example, each human cell has around 2m, or 3 billion base pairs, of DNA that must be compacted to fit within the nucleus.
What is the function of a eukaryotic chromosome?
Eukaryotic chromosomes are found in the cell’s nucleus. This nucleus is the “control center” of the cell that stores all the cell’s genetic information, or DNA.
What can the eukaryotic chromosome be described as?
Eukaryotic chromosomes consist of a DNA-protein complex that is organized in a compact manner which permits the large amount of DNA to be stored in the nucleus of the cell. The subunit designation of the chromosome is chromatin. The fundamental unit of chromatin is the nucleosome.
What are the key features of eukaryotic chromosomes quizlet?
The eukaryotic chromosome is made up of chromatin, a linear DNA strand that is bound to and wrapped around histones, which are proteins that keep DNA from getting tangled and enable it to be packed inside the nucleus in an orderly way. contain free-floating linear chromosomes within a nucleus.
What is the composition of eukaryotic chromosomes quizlet?
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. These DNA and protein structures pack together to form condensed coils.
Why are eukaryotic chromosomes linear?
In most eukaryotic cells, DNA is arranged in multiple linear chromosomes. This is a phenomenon which occurs due to the directionality of DNA replication enzymes, resulting in the gradual loss of genetic material at the ends of linear chromosomes after each subsequent cycle of cell and DNA replication.
What are the two main components of eukaryotic chromosomes quizlet?
Eukaryotic chromosomes are made up of DNA that is tightly wound around histone molecules. These DNA and protein structures pack together to form condensed coils. You just studied 8 terms!
How do prokaryotic and eukaryotic chromosomes differ quizlet?
What is the difference between prokaryotic chromosomes and eukaryotic chromosomes? Prokaryotic cells have a single circular chromosomes attached to the cell membrane, while eukaryotic cells contain free-floating linear chromosomes within a nucleus.
How does the function and structure of the chromosome differ in prokaryotes quizlet?
The function and structure of the chromosome differ in prokaryotes. The DNA in Prokaryotic and Eukaryotic cells contain genetic information, but Prokaryotes have a circular DNA and don’t have histones.
How do eukaryotic chromosomes condense?
Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5). However, when eukaryotic cells are not dividing — a stage called interphase — the chromatin within their chromosomes is less tightly packed.
Why do eukaryotic chromosomes need to be compacted?
Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes. The way in which eukaryotes compact and arrange their chromatin not only allows a large amount of DNA to fit in a small space, but it also helps regulate gene expression.
How do eukaryotic chromosomes differ from bacterial chromosomes?
How does a bacterial chromosome differ from a eukaryotic chromosome? A bacterial chromosome is a circular, double-stranded DNA molecule with associated proteins. A eukaryotic chromosome is a linear, double-stranded DNA molecule with many associated proteins, including histones.
