Expert writing Tips
Best practice
When describing the arrangement of genes or DNA sequences, use "head to head orientation" to clearly indicate that the genes are transcribed in opposite directions from a shared or nearby regulatory region.
Common error
Avoid using "head to head orientation" when you actually mean tail-to-tail or tandem orientation. Ensure that the elements you are describing are indeed facing each other directly, not aligned in the same direction or opposite but offset.
