Stentor coeruleus, used in molecular biology (its genome has been sequenced), [5] and is studied as a model of single-cell regeneration.; Dictyostelium discoideum, used in molecular biology and genetics (its genome has been sequenced), and is studied as an example of cell communication, differentiation, and programmed cell death.
Saccharomyces cerevisiae was the first eukaryotic organism to have its complete genome sequence determined.. This list of "sequenced" eukaryotic genomes contains all the eukaryotes known to have publicly available complete nuclear and organelle genome sequences that have been sequenced, assembled, annotated and published; draft genomes are not included, nor are organelle-only sequences.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
This list of sequenced animal genomes contains animal species for which complete genome sequences have been assembled, annotated and published. Substantially complete draft genomes are included, but not partial genome sequences or organelle-only sequences.
The HapMap is a haplotype map of the human genome, "which will describe the common patterns of human DNA sequence variation." [77] It catalogs the patterns of small-scale variations in the genome that involve single DNA letters, or bases.
For example, some proteins have parts of their surface that perfectly match the shape of another molecule, allowing the protein to bind to this molecule very tightly. Other proteins are enzymes, which are like tiny machines that alter other molecules. [7] The information in DNA is held in the sequence of the repeating units along the DNA chain. [8]
Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.
The new human pangenome reference integrates the missing 8% of the human genome sequence, adding over 100 million new bases. It aims to capture more population diversity than the previous reference sequence and is based on 94 high-quality haploid assemblies from individuals with broad genetic diversity.
