In 2003, estimates from gene-prediction programs suggested there might be 24,500 or fewer protein-coding genes. The Ensembl genome-annotation system estimates them at 23,299.
When analysis of the draft human genome sequence was published by the International Human Genome Sequencing Consortium on February 15, 2001, the paper estimated only about 30,000 to 40,000 protein-coding genes, much lower than previous estimates of about 100,000. This lower estimate came as a shock to many scientists because counting genes was viewed as a way of quantifying genetic complexity. With about 30,000, the human gene count would be only one-third greater than that of the simple roundworm C. elegans, which has about 20,000 genes.
Studies since the publication of the draft genome sequence have generated widely different estimates. An analysis by scientists at Ohio State University suggested between 65,000 and 75,000 human genes, and another study published in Cell in August 2001 predicted a total of 42,000
Although the completion of the Human Genome Project was celebrated in April 2003 and sequencing of the human chromosomes is essentially "finished," the exact number of genes encoded by the genome is still unknown. October 2004 findings from The International Human Genome Sequencing Consortium, led in the United States by the National Human Genome Research Institute (NHGRI) and the Department of Energy (DOE), reduce the estimated number of human protein-coding genes from 35,000 to only 20,000-25,000, a surprisingly low number for our species. Consortium researchers have confirmed the existence of 19,599 protein-coding genes in the human genome and identified another 2,188 DNA segments that are predicted to be protein-coding genes.

It could be years before a truly reliable gene count can be assessed. The reason for so much uncertainty is that predictions are derived from different computational methods and gene-finding programs. Some programs detect genes by looking for distinct patterns that define where a gene begins and ends ("ab initio" gene finding). Other programs look for genes by comparing segments of sequence with those of known genes and proteins (comparative gene finding). While ab initio gene finding tends to overestimate gene numbers by counting any segment that looks like a gene, comparative gene finding tends to underestimate since it is limited to recognizing only those genes similar to what scientists have seen before. Defining a gene is problematic because small genes can be difficult to detect, one gene can code for several protein products, some genes code only for RNA, two genes can overlap, and many other complications.
Even with improved genome analysis, computation alone is simply not enough to generate an accurate gene number. Clearly, gene predictions will have to be verified by labor-intensive work in the laboratory before the scientific community can reach any real consensus.

Pretty sure some did, especially the ones that didn't expect much.
During a nonexplosive eruption, you can expect to see a steady flow of lava mainly from fissures or vents on the volcano. This type of eruption typically causes slow-moving lava flows, rather than dramatic explosions. Ash and gas emissions may still occur but are usually not as intense as in explosive eruptions.
Yes, a field guide typically includes both common names and scientific names of species to help readers easily identify and learn about the organisms being described. Common names can vary regionally, so including scientific names provides a universal reference point for accurate identification.

Scientists using classical Newtonian physics would expect to observe a gradual increase in the kinetic energy of emitted electrons when exposed to increasing light intensity in the photoelectric effect. They would also expect the emission of electrons to start immediately upon exposure to light, regardless of its frequency.
The salary of a medical scientist can vary depending on factors such as experience, location, and employer. On average, a medical scientist can expect to earn around $6,000 to $8,000 per month.
