Final answer:
It's true that only a small fraction of TEs in the human genome can move to new locations, with the majority being inactive due to mutations or host control mechanisms.
Step-by-step explanation:
The statement "Only a small fraction of TEs (transposable elements) in the human genome have the ability to move to a new location" is A. True. Transposable elements, also known as jumping genes, are sequences that can change their position within the genome. Although they make up a significant portion of the human genome, most of the TEs have lost their ability to move due to mutations or regulatory mechanisms that have been adopted by the host to minimize their potentially harmful effects. A small fraction of TEs, however, remain active and can transpose, contributing to genetic diversity and sometimes causing genetic disorders.
