Question

Quizplus · Accepted Answer

SINE elements are evolutionarily related to tRNA sequences. SINE stands for Short INterspersed Elements, which are non-coding DNA sequences that have a length of around 100-400 base pairs and are transposable. They are so-called because they are interspersed between other genomic sequences. SINEs are derived from tRNA genes and have a similar secondary structure. They are found in many organisms, including humans, and can make up a large proportion of the genome.
