The human genome is composed of many different types of DNA sequences, the majority of which do not encode proteins. From the following distribution and amount of each of the various types of sequences determine which of these is CORRECTLY expressed?

#Unit 2. Cellular Organization

More than 60% of the human genome is composed of intergenic sequences, and much of this DNA has no known function. About one-quarter of the intergenic DNA is repeated.
Pseudogenes arise from the action of an enzyme called reverse transcriptase. This enzyme copies RNA into double-stranded DNA (referred to as copy DNA or cDNA).
Microsatellite DNA is composed of very short (13 bp), tandemly repeated sequences. The most common microsatellite sequences are dinucleotide repeats (e.g., GAGAGAGAGAGAGAGA).
Transposable elements are sequences that can “move” from one place in the genome to another and they now comprise 60% of the human genome due to their successful rate of propagation.
