http://hl7.org/fhir/uv/molecular-definition-data-types/CodeSystem/strand-orientation  forwardForward strand5' 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.
http://hl7.org/fhir/uv/molecular-definition-data-types/CodeSystem/strand-orientation  reverseReverse strand3' to 5' orientation; also known as negative/minus strand. Applicable only to double stranded sequences.
