- The sequence of bases along a strand of DNA determines the genetic code. When the product of a particular gene is needed, the portion of the DNA molecule that contains that gene will split.

The Gene Ontology (GO) provides a framework and set of concepts for describing the functions of gene products from all organisms. It is specifically designed for supporting the computational representation of biological systems.
Ultimately, one wishes to determine how genes—and the proteins they encode—function in the intact organism. Although it may sound counterintuitive, one of the most direct ways to find out what a gene does is to see what happens to the organism when that gene is missing.

Gene expression and regulation describes the process by which information encoded in an organism's DNA directs the synthesis of end products, RNA or...
Mar 30, 2024 · Gene expression is a series of steps by which information encoded in genes creates functional products, such as RNA or proteins. It is a fundamental process that plays a crucial role in all living organisms’ development, functioning, and regulation.
2 days ago · Gene expression is the process by which the information encoded in a gene is turned into a function. This mostly occurs via the transcription of RNA molecules that code for proteins or non-coding RNA molecules that serve other functions.
A gene is a region of DNA that encode a gene product, either an mRNA that itself encodes a polypeptide or a “non-coding” RNA that functions as an RNA. The gene also includes the sequences required for its proper expression, that is, when and where the gene is active, when RNAs are made from it.
Oct 31, 2023 · Genes are composed of DNA arranged on chromosomes. Some genes encode structural or regulatory RNAs. Other genes encode proteins. Replication copies DNA; transcription uses DNA to make complementary RNAs; translation uses mRNAs to make proteins.
