Gene Wikipedia ~ A chromosome consists of a long strand of DNA containing many genes A human chromosome can have up to 500 million base pairs of DNA with thousands of genes In biology a gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product either RNA or protein

Genoa Wikipedia ~ Genoa is a port city by birth establishing itself as the merchant capital of the newly established Republic of Genoa in 1005 and maintaining its autonomy until 1797 Genoa was a powerful port and briefly entered in conflict with Venice over the Mediterranean Trade

Genetics Wikipedia ~ Genetics is a branch of biology concerned with the study of genes genetic variation and heredity in organisms Though heredity had been observed for millennia Gregor Mendel a scientist and Augustinian friar working in the 19th century was the first to study genetics scientifically Mendel studied trait inheritance patterns in the way traits are handed down from parents to offspring

Genome Wikipedia ~ In the fields of molecular biology and genetics a genome is the genetic material of an organism It consists of DNA or RNA in RNA virusesThe genome includes both the genes the coding regions and the noncoding DNA as well as mitochondrial DNA and chloroplast study of the genome is called genomics

Housekeeping gene Wikipedia ~ Housekeeping gene regulation Housekeeping genes account for majority of the active genes in the genome and their expression is obviously vital to survival The housekeeping gene expression levels are finetuned to meet the metabolic requirements in various tissues

Human genome Wikipedia ~ The 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 are usually treated separately as the nuclear genome and the mitochondrial genome Human genomes include both proteincoding DNA genes and noncoding DNA

Lists of human genes Wikipedia ~ Proteincoding genes The lists below constitute a complete list of all known human proteincoding genes sorted alphanumerically by the HGNCapproved gene symbol List of human proteincoding genes 1 List of human proteincoding genes 2

History of genetics Wikipedia ~ In 1910 Thomas Hunt Morgan showed that genes reside on specific chromosomes He later showed that genes occupy specific locations on the chromosome With this knowledge Alfred Sturtevant a member of Morgans famous fly room using Drosophila melanogaster provided the first chromosomal map of any biological organism

Gene expression Wikipedia ~ Some housekeeping genes are transcribed at a relatively constant rate and these genes can be used as a reference point in experiments to measure the expression rates of other genes A facultative gene is a gene only transcribed when needed as opposed to a constitutive gene
