CodeSystem: Strand Orientation

Official URL: http://hl7.org/fhir/uv/molecular-definition-data-types/CodeSystem/strand-orientation Version: 1.0.0-ballot1
Standards status: Draft Maturity Level: 0 Computable Name: StrandOrientation

Orientation of molecular sequences, indicating directionality for nucleotides (5' to 3' or 3' to 5') or amino acids (N to C terminus)

This Code system is referenced in the content logical definition of the following value sets:

This case-sensitive code system http://hl7.org/fhir/uv/molecular-definition-data-types/CodeSystem/strand-orientation defines the following codes:

CodeDisplayDefinition
forward Forward strand 5' to 3' for nucleotides or N-to-C for amino acids; also known as positive/plus strand. Single stranded sequences are conventionally represented in forward direction.
reverse Reverse strand 3' to 5' orientation; also known as negative/minus strand. Applicable only to double stranded sequences.
