Sequence Length
Count the number of characters in a nucleotide sequence.
Description
Count the number of characters in a nucleotide sequence.
Sequence Length is a focused biology tool that count the number of characters in a nucleotide sequence. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use Sequence Length
Use Sequence Length when you need to count the number of characters in a nucleotide sequence. Enter Sequence using the definitions and units below so the result can be reproduced.
- Sequence
- A sequence, category, or text value.
How Sequence Length calculates the result
The published tool contract uses this rule: Count the number of characters in a nucleotide sequence.
- Length
- The calculated length in nt.
Limitations of Sequence Length
The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.
Alternative or Complementary measurements
Retain the original Sequence 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.
