One obvious belief for this was the sheer number of genes present in complex organisms. However, over the years, scientists have learnt that the size of the genome is not related to the genetic complexity of the organism. chronic migraine statistics

WebJul 19, 2024 · The amount of genomic DNA in complex eukaryotes is much greater than the amount needed to encode proteins. For example: Mammals have 30,000 to 50,000 genes, but their genome size (or C-value) is 3 x 10 9 bp. (4.5.1) 3 × 10 9 base pairs 3000 base paires (average gene size) = 1 × 10 6 (“gene capacity”). WebThe complexity of the eukaryotic genome necessitates a great variety and complexity of gene expression control. Eukaryotic transcription proceeds in three sequential stages: initiation, elongation, and termination. [1] The RNAs transcribed serve diverse functions.
