Many genomes have been sequenced and their gene sequences are stored in general DNA sequence databases (e.g. GenBank) and in species specific databases (e.g. The Arabidopsis Information Resource (TAIR). Genome is also a popular science book by Matt Ridley. ... In genetics and biochemistry, sequencing means to determine the primary structure (or primary sequence) of an unbranched biopolymer. ... The GenBank sequence database is an annotated collection of all publicly available nucleotide sequences and their protein translations. ... Species See text. ...

The figures are views of the sequence of one (AMY1) of the approximately 25,000 genes from Arabidopsis thaliana the thale cress plant. This gene encodes an alpha amylase enzyme. Binomial name Arabidopsis thaliana (L.) Heynh. ... α-Amylase Amylase (EC 3. ...

These images are views of the gene, cDNA, and coding sequence (CDS) used by researchers to study it further. Such research might involve seed germination or plant flavour. CDS may refer to: Commercial Data Systems, Ltd. ...

cDNA

The image below shows a screenshot of the AMY1 cDNA. This was obtained from TAIR In genetics, complementary DNA (cDNA) is single-stranded DNA synthesized from a mature mRNA template. ...

Note that TAIR provide three views of the 'Nucleotide Sequence', 'full length CDS', 'full length cDNA' (Fig. 1), 'full length genomic' (Fig. 2]. In each of them the DNA alphabet is used, although strictly the CDS should be shown as RNA (AUG etc).

A typical eukaryotic gene is transcribed into an RNA that is then processed into a mature mRNA by removal of introns and 5' and 3' processing. Ribonucleic acid (RNA) is a nucleic acid polymer consisting of nucleotide monomers. ... The interaction of mRNA in a eukaryote cell. ... Diagram of the location of introns and exons within a gene. ...

Gene

The mRNA is comprised of a 5' UTR (red) CDS (uppercase yellow) and 3' UTR (red again). All three of these regions are exonic (not just the CDS). Introns are shown in purple (lowercase). For convienience neither the 5' Cap nor 3' tail are shown in the cDNA (fig 1) although the mRNA will have them. The gene sequence is also shown in a form where the codons can be read (ATG...), rather than as the template DNA strand which is actually copied into mRNA. In eukaryotic genetics, the 5 UTR (read as 5 prime UnTranslated Region) is a particular section of messenger RNA (mRNA). ... CDS may refer to: Commercial Data Systems, Ltd. ... In genetics, the 3 UTR (read as 3 prime untranslated region) is a particular section of messenger RNA (mRNA). ... Look up template in Wiktionary, the free dictionary. ...

This gene structure view is typical of a eukaryotic gene. Similar views of genes can be obtained for human, fruitfly, or yeast genes. Trinomial name Homo sapiens sapiens Linnaeus, 1758 Humans, or human beings, are bipedal apes belonging to the mammalian species Homo sapiens (Latin for wise man or knowing man) under the family Hominidae (known as the great apes). ... Wikipedia does not yet have an article with this exact name. ... It has been suggested that Yeast (baking) be merged into this article or section. ...
