The nucleolus is a dense spherical structure within the nucleus where ribosomal RNA (rRNA) is transcribed and ribosomal subunits are assembled. They then exit to the cytoplasm. The cytoplasm is the site of translation. Mitochondria have their own 70S ribosomes but their rRNA is synthesized within the organelle. Golgi modifies proteins.

Explanation:
DNA fingerprinting (DNA profiling) is a technique used to identify individuals based on their unique DNA patterns. It primarily relies on the analysis of Variable Number Tandem Repeats (VNTRs) or Short Tandem Repeats (STRs), which are highly polymorphic, non-coding, repetitive DNA sequences that vary greatly in length and number between individuals.
