Multiple linear chromosomes are found in
WebProkaryotic genomes are efficient and compact, containing little repetitive DNA. Eukaryotes contain multiple linear chromosomes. Eukaryotic chromosomes are condensed in a membrane-bound nucleus ... WebEukaryotic Chromosomes. The genome within a eukaryotic cell is subdivided into multiple chromosomes. Each eukaryotic chromosome is a single linear double-stranded DNA molecule that is approximately 10–100 million base pairs (bp) in length (see Figure 1.2).

WebRepetitive regions at the very ends of chromosomes are called telomeres, and they're found in a wide range of eukaryotic species, from human beings to unicellular protists. … Each eukaryotic chromosome consists of a long linear DNA molecule associated with proteins, forming a compact complex of proteins and DNA called chromatin. Chromatin contains the vast majority of the DNA of an organism, but a small amount inherited maternally, can be found in the mitochondria. It is present in most cells, with a few exceptions, for example, re…
WebChromosomes are found carrying your DNA in the nucleus of your cells. DNA looks like a spiral staircase (double helix). The rungs are base pairs and the rails are sugar and phosphate molecules. What is DNA? Deoxyribonucleic acid (DNA) is the material that exists in every cell in your body that holds your genetic code. WebInterestingly, circular chromosomes are also found in mitochondria and chloroplasts. They both use their own DNA to make some proteins needed for their function. This gives …
