Unformatted text preview: 42 Note: Print out extra copies of pp. 50-51 to use in Discussion. 7.1. Overall content of the human genome (B. Alberts et al., Molecular Biology of the Cell , 2008). Haploid size: 3.2 billion bp. Genes: approx 22,500 Av. gene length: 27 kb. Av. exons/gene: 10.4 % DNA in exons: 1.5% % DNA in other highly conserved sequences: 3.5% pseudogenes: more than 20,000 7.2. Transposon derived repeat sequences make up about 45% of the human genome, Fig. 13.27 (14.27). This is sometimes called selfish DNA since it can multiply itself. It also has the ability to copy and move genes, leading to gene families. 43 7.3. Retroposons Fig. 13.26 (14.26) Mammals have 2 major types of retroposons: LINEs are long interspersed elements, usually 1-5 kb long, and SINEs are short interspersed elements, usually 200-500 bp long. 7.4. How transposable elements (TEs) can create repeats and also move genes, Fig. 13.29 (14.29). 7....
