The human genome has many different regulatory sequences which are crucial to controlling gene expression. Conservative estimates indicate that these sequences make up 8% of the genome, [29] however extrapolations from the ENCODE project give that 20 [30] or more [31] of the genome is gene regulatory sequence.
The human genome is the total collection of genes in a human being contained in the human chromosome, composed of over three billion nucleotides. [2] In April 2003, the Human Genome Project was able to sequence all the DNA in the human genome, and to discover that the human genome was composed of around 20,000 protein coding genes.
Human genome projects are scientific endeavors that determine or study the structure of the human genome. The Human Genome Project was a landmark genome project. There are numerous related projects that deal with genetic variation (or variation in the encoded proteins), e.g. organized by the following organizations: HUman Genome Organisation ...
Genetic variation can be identified at many levels. Identifying genetic variation is possible from observations of phenotypic variation in either quantitative traits (traits that vary continuously and are coded for by many genes, e.g., leg length in dogs) or discrete traits (traits that fall into discrete categories and are coded for by one or a few genes, e.g., white, pink, or red petal color ...
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological , medical , historical and forensic implications and applications.
The microscopic nematode Caenorhabditis elegans, for example, is composed of only a thousand cells but has about the same number of genes as a human. [ 1 ] [ 2 ] Researchers suggest resolution of the paradox may lie in mechanisms such as alternative splicing and complex gene regulation that make the genes of humans and other complex eukaryotes ...
In the human genome project the human genome was successfully sequenced, which provided a reference human genome for comparison of genetic variation. With improving sequencing technologies and the reference genome, more and more variations were found of several different sizes that were larger than 1 kb but smaller than microscopic variants.
