WebAnswer. The 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. Web9 de nov. de 2005 · Prokaryotic genes are often organized into operons that are transcribed into polycistronic units, whereas with few exceptions, eukaryotic genes are transcribed as single-gene units. Unlike prokaryotic genes, eukaryotic genes often have complex regulatory regions, and in multicellular species such regions often have a modular …
Webgene, unit of hereditary information that occupies a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins. In eukaryotes (such as animals, plants, and fungi), genes are contained within the cell nucleus. The mitochondria (in animals) and the chloroplasts (in plants) also contain small subsets of genes distinct … WebUnit 3: How Are Eukaryotic Cells Organized into Smaller Parts?
