Use Transcript Length nt when you need to report the length of a transcript in nucleotides. Enter Transcript length using the definitions and units below so the result can be reproduced.

Transcript length

An integer count or setting greater than or equal to 1, expressed in nt.

The published tool contract uses this rule: Report the length of a transcript in nucleotides.

Transcript length

The calculated transcript length in nt.

The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.

Retain the original Transcript length values and their units alongside the result. Gene Coordinate Length is useful when you instead need to calculate gene length from one-based inclusive start and end coordinates: end − start + 1. Inclusive coordinates count both endpoint bases, so a feature whose start and end are equal is one base pair long. Fragment Lengths Count provides another view by helping you compute the number of DNA fragments produced by a number of restriction cut sites.

• Gene Coordinate Length

  Calculate gene length from one-based inclusive start and end coordinates: end − start + 1. Inclusive coordinates count both endpoint bases, so a feature whose start and end are equal is one base pair long.

• Fragment Lengths Count

  Compute the number of DNA fragments produced by a number of restriction cut sites.

• Sequence Length

  Count the number of characters in a nucleotide sequence.
