Before the human genome was sequenced by the Human Genome Project, scientist expected that they would find about 100,000 genesIn fact, they discovered that humans have only 25 000 genes which statement best explains this discrepancy in numbers? A) Human error caused scientists to estimate the wrong number of genes found in the human genome.

B) Alternative RNA splicing, different molecules are produced from the same primary transcript, depending on which RNA segments are treared as exons and which introns.

C) A wobble where some molecules have anticadors can recognize two or more different because the pairing rules for the third base of a codon are not as strict as they are for the first two bases.
