17 Facts About Human genome

Human genome is a complete set of nucleic acid sequences for humans, encoded as DNA within the 23 chromosome pairs in cell nuclei and in a small DNA molecule found within individual mitochondria.

Recent results suggest that most of the vast quantities of noncoding DNA within the Human genome have associated biochemical activities, including regulation of gene expression, organization of chromosome architecture, and signals controlling epigenetic inheritance.

The human genome was the first of all vertebrates to be sequenced to such near-completion, and as of 2018, the diploid genomes of over a million individual humans had been determined using next-generation sequencing.

The complete human genome was published in 2021, while with Y chromosome in January 2022.

The haploid Human genome is 3 054 815 472 base pairs, when the X chromosome is included, and 2 963 015 935 base pairs when the Y chromosome is substituted for the X chromosome.

The Human genome includes the mitochondrial DNA, a comparatively small circular molecule present in multiple copies in each mitochondrion.

Content of the human genome is commonly divided into coding and noncoding DNA sequences.

The exploration of the function and evolutionary origin of noncoding DNA is an important goal of contemporary genome research, including the ENCODE project, which aims to survey the entire human genome, using a variety of experimental tools whose results are indicative of molecular activity.

Non-coding DNA greatly outnumbers coding DNA, the concept of the sequenced Human genome has become a more focused analytical concept than the classical concept of the DNA-coding gene.

The complete modular protein-coding capacity of the Human genome is contained within the exome, and consists of DNA sequences encoded by exons that can be translated into proteins.

Noncoding DNA is defined as all of the DNA sequences within a Human genome that are not found within protein-coding exons, and so are never represented within the amino acid sequence of expressed proteins.

Human genome has many different regulatory sequences which are crucial to controlling gene expression.

For example, a much larger fraction of the Human genome is thought to be involved in copy number variation.

Personal Human genome sequence is a complete sequence of the chemical base pairs that make up the DNA of a single person.

In 2009, Stephen Quake published his own Human genome sequence derived from a sequencer of his own design, the Heliscope.

Since then hundreds of personal Human genome sequences have been released, including those of Desmond Tutu, and of a Paleo-Eskimo.

Personal genomics helped reveal the significant level of diversity in the human genome attributed not only to SNPs but structural variations as well.
