	A standard biological part is a functional unit of DNA that encodes for a specific biological function. Parts have been standardized so that they can be used to efficiently develop biological systems in living cells.

What are standard biological parts

Example needed (besides Lego) - Hardware store? Electronic components? Picture needed!

A standard biological part (or simply, part) is a sequence of DNA that encodes for a biological function. At its simplest, a basic part is a single functional unit that cannot be divided further into smaller functional units, but basic parts can be assembled together to make longer, more complex composite parts. The Registry organizes these parts by type/function which means that you can search for or create . You can find more information about part types on the part catalog. You might come to the Registry to look for a promoter that can be induced by

If you wanted to build a traditional electronic device you would go to an electronics store to pick up a transistor, capacitor, or motor. You would come to the Registry to get a promoter, ribosome binding site, or coding region to build a biological machine. Ultimately, parts can be assembled together to create biological systems in cells.

Why use Registry parts?

Coupled with their functional organization, parts can be easily assembled together. You can take a promoter, add a ribosome binding site, then a protein coding region, and finally a terminator.

Why are parts easily assembled?

is flanked on both ends with standard sequences, referred to as a prefix and suffix. The prefix and suffix contain restriction sites, which when used with a restriction enzyme (cutting) and DNA ligase (connecting), allows parts to be assembled together forming a new part.

The specific sequences of the prefix and suffix of a part are defined by their <a href="https://parts.igem.org/Help:Standards">standard</a>. All parts belonging to a standard will have the same prefix and suffix. This means that anyone can join two parts within a standard. The BioBrick (RFC10) standard is the

Different standards

The Registry supports several standards, and among them the BioBrick standard is currently the most used. To accommodate the needs of building different systems with different methods, there
