What it does and how to use it
A skill that teaches Claude Code to do scientific tasks well. It is packaged knowledge the model uses whenever it is relevant.
- Install the skill (command above).
- In Claude Code, describe what you need - the skill turns on by itself when the context fits.
- No commands to memorize: you talk in plain language and the skill does the rest.
Install (Claude Code)

# Sequence Handling with Bio.Seq and Bio.SeqIO
## Overview
Bio.Seq provides the `Seq` object for biological sequences with specialized methods, while Bio.SeqIO offers a unified interface for reading, writing, and converting sequence files across multiple formats.
## The Seq Object
### Creating Sequences
```python
from Bio.Seq import Seq
# Create a basic sequence
my_seq = Seq("AGTACACTGGT")
# Sequences support string-like operations
print(len(my_seq)) # Length
print(my_seq[0:5]) # Slicing
```
### Core Sequence Operations
```python
# Complement and reverse complement
complement = my_s
