Hedgehog protein with autoproteolytic activity that cleaves off the C-terminus to reveal a signal sequence that marks the protein for secretion.

#Unit 3. Fundamental Processes

The protospacer adjacent motif (or PAM for short) is a short DNA sequence (usually 2-6 base pairs in length) that follows the DNA region targeted for cleavage by the CRISPR system, such as CRISPR-Cas9. The PAM is required for a Cas nuclease to cut and is generally found 3-4 nucleotides downstream from the cut site

Type of iteroparity

Seasonal iteroparity- Many species, such as birds or mammals, or temperate forest trees, have distinct breeding seasons Continuous iteroparity- individuals reproduce repeatedly and at any time of the year.
