How does the nuclear genome of the trypanosomes differ from euk. genome
Added by Brandon O.
Step 1
- Eukaryotic genomes typically consist of a single, linear chromosome set within a nucleus, containing DNA associated with various proteins to form chromatin. Show more…

There is an enormous variation in genome size, but the organismal complexity does not correlate well with genome size. Most eukaryotic nuclear genomes are made of multiple linear chromosomes. In addition to the main nuclear genome, eukaryotic genome complexity is increased with the genes of mitochondria and chloroplasts. Transposable elements make up a large portion of eukaryotic genomes. A very large fraction of eukaryotic genomes codes for proteins.

Based on the figure below, which of the following statements is true? Eukaryotic genome size ranges in bp 10^7 10^8 10^9 10^10 10^11 Fungi / Moulds Algae Worms Insects Mollusks Birds Bony fish Reptiles Mammals Amphibians Flowering plants Small Medium Large Trends in Plant Science Figure 1. Eukaryotic Genome Size Ranges in Base Pairs. Small to very small (<500 Mbp), very large (>10 Gbp), and medium-sized (1- < 10 Gbp) genomes preferentially follow shrinkage, expansion, and equilibrium strategies, respectively, during genome size evolution. Adapted from Wikipedia. Schubert, I., and G. T. H. Vu. 2016. Genome stability and evolution: Attempting a holistic view. Trends in Plant Science 21(9): 749-757. Genome size is an adaptation for eukaryotic organisms but not for prokaryotic organisms Non-coding sequences are more common in mammals than in reptiles.
