Which of the following statements is INCORRECT with respect to the organization and content of the human genome?

#Unit 2. Cellular Organization

  1. More than 60% of the human genome is composed of intergenic sequences, and much of this DNA has no known function.

  2. The most common microsatellite sequences are dinucleotide repeats (e.g., CACACACACACACACA). They represent nearly 5% of the human genome.

  3. Genome-wide repeats are much larger than their microsatellite counterparts. Each genome-wide repeat unit is >100 bp in length and many are >1 kb.

  4.  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).
