Algae can exist in many sizes ranging from single cells to giant kelps several feet long. A computer program typically consists of several algorithms. A population or species of organisms typically includes multiple alleles at each locus distributed among various individuals; except very rarely, each individual can have only two alleles at a given locus. Allelic variation at a locus is measurable as the number of alleles polymorphism present, or the proportion of heterozygotes in the population.

CO 2 is emitted from a variety of processes e. CO 2 is a greenhouse gas that absorbs infrared radiation and traps heat in Earth's atmosphere.
Calvincycle Calvin cycle A series of photosynthetic chemical reactions that do not require light to occur. The Calvin cycle uses energy produced by light-dependent reactions of photosynthesis to incorporate carbon from carbon dioxide into organic compounds used to make sugars, starches, and other biological molecules.
The global flow of carbon from one reservoir carbon sink to another. Each carbon exchange among reservoirs is mediated by a variety of physical, biogeochemical, and human activities. CO 2 is a greenhouse gas that absorbs infrared radiation and traps heat in the Earth's atmosphere. For example, if the net exchange between the biosphere and the atmosphere is toward the atmosphere, the biosphere is the source, and the atmosphere is the sink.

These molecules bind selectively to the target DNA. Once bound, the chimeraplast activates a naturally occurring gene-correcting mechanism. Does not use viral or other conventional gene-delivery vectors. See also: cloning vector chlorophyll Chlorophyll A type of green pigment used to harness light energy in the chloroplasts of plants and other photosynthetic organisms. It contains chlorophyll and functions in photosynthesis and protein synthesis.
The gene sequence for the segment is reversed with respect to the rest of the chromosome. In prokaryotes, chromosomal DNA is circular, and the entire genome is carried on one chromosome. Eukaryotic genomes consist of a number of chromosomes whose DNA is associated with different kinds of proteins. Climate is largely determined by local geographical features, latitude, altitude, land- and sea-masses, and atmospheric circulation patterns. The resulting cloned copied collections of DNA molecules are called clone libraries.
A second type of cloning exploits the natural process of cell division to make many copies of an entire cell. The genetic makeup of these cloned cells, called a cell line, is identical to the original cell. See also: cloning vector cloningvector Cloning vector DNA molecule originating from a virus, a plasmid, or the cell of a higher organism into which another DNA fragment of appropriate size can be integrated without loss of the vector's capacity for self-replication; vectors introduce foreign DNA into host cells, where the DNA can be reproduced in large quantities.
Examples are plasmids, cosmids, and yeast artificial chromosomes; vectors are often recombinant molecules containing DNA sequences from several sources. See also: recessive gene codon Codon See: genetic code cofactor Cofactor An organic or inorganic substance required by an enzyme to function.

Genomic Science Program
The initial deposition of a sequence record is referred to as version 1. If the sequence is updated, the version number is incremented but the accession number will remain constant. Most often used for the detection of copy number variation CNV , aCGH also has applications in gene annotation and diagnostics. Read more about aCGH. Mantripragada, K. Wong, K.
Glossary of Genomics Terms
Variations in clinical traits and phenotypes are allelic if they arise from the same gene sequence or locus and nonallelic if they arise from different gene sequences of different loci. Alternative splicing: Use of different exons in formation of mRNA from initially identical transcripts. This results in the generation of related proteins from one gene, often in a tissue or developmental stage—specific manner. Analytical validity: The likelihood that a test result is correct, ie, a specific variant said to be present is present or said to be absent is absent. Array: See Microarray.
Genomics is an interdisciplinary field of 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. In contrast to genetics , which refers to the study of individual genes and their roles in inheritance, genomics aims at the collective characterization and quantification of all of an organism's genes, their interrelations and influence on the organism. In turn, proteins make up body structures such as organs and tissues as well as control chemical reactions and carry signals between cells. Genomics also involves the sequencing and analysis of genomes through uses of high throughput DNA sequencing and bioinformatics to assemble and analyze the function and structure of entire genomes.
Allele Frequency : The proportion of a particular allele among the chromosomes carried by individuals in a population. Amino acid : Any of a class of 20 molecules that are combined to form proteins in living things. The sequence of amino acids in a protein and hence protein function are determined by the genetic code. Amplification : An increase in the number of copies of a specific DNA fragment; can be in vivo or in vitro. Autosome : A chromosome not involved in sex determination.
