The y chromosome, which only contains a few hundred genes.
The human genome contains about 24,000 genes.
55 orthologous genes are associated with human height
The average human possesses around 20,000 to 25,000 genes.
There are estimated to be 26000 genes after completing the human genome project.
This results in bacteria expressing human proteins or genes.
Most, but not all human genes have been identified and named.
Fertilization is important so species can have genetic variation. It is also important so the species can pass on their genes.
Yes, but that does not mean that any viable creature might develop. There are very few limits to what genes can be inserted into what - quite a few creatures have gained fluorescing genes from jellyfish, including mice, and antifreeze genes from an arctic fish have been inserted into a soft fruit (raspberries I think).
Yes, bacteria can be genetically modified to express human genes. This is commonly done in biotechnology and genetic engineering for purposes such as protein production, drug development, and studying genetic diseases. The human genes are inserted into bacterial cells, which then produce the corresponding human proteins.
· Presence of the UTRs in the first and last exons makes it difficult to annotate the genes, and the human genes have 40% non-coding first exons UTRs thus making it difficult to decide how many genes are in the genome.· Most gene finders cannot handle alternative splicing, cannot handle overlapping or nested genes and also algorithms are trained with sequences from known genes which biases them against genes about which nothing is known
There are approximately 20,000 to 25,000 protein-coding genes in the human genome.
