Final answer:
DNA sequences from transposable elements are not rare but are quite common in the human genome, contributing to its complexity and diversity.
Step-by-step explanation:
Are DNA sequences derived from transposable elements rare in the human genome? The correct answer is False. Transposable elements are actually quite common in the human genome. They are sequences of DNA that can change their position within the genome, potentially causing mutations or altering the cell's genetic identity and its genomic size. These elements make up a significant portion of the human genome; in fact, a large part of eukaryotic genomes is made up of repetitive DNA sequences, which include transposable elements. This prevalence has been crucial in shaping genomes over evolutionary time and can have specific functions such as regulating gene expression and increasing genetic diversity.
