Abstract: | The sizes of nucleotide sequences of chromosomes 21 and 22 of the human genome established in three independent laboratories were compared with the sizes expected from the accurately determined contribution of these chromosomes to the genome mass. It was found that the expected haploid mass of the genome is about twofold smaller than the lowest of the figures published. This strongly contradicts the current notions about the genome size. With the bineme model of chromosome, the expected overall length of the human genome is close to 2100 Mbp and the haploid mass is close to 4200 Mbp. According to the calculations performed, the bineme chromosome structure enhances the reliability of the genome about 1.6 x 10(8)-fold (the computations are given in the paper). |
