A DNA Collector is a person who collects and stores DNA samples for research or legal purposes. The term 'DNA Collector' can be abbreviated to 'SWAB, ' which is a four-letter word that can be found in crosswords. Collecting DNA samples involves using swabs to take samples from the inside of a person's cheek, which are then stored for further analysis. DNA Collectors must ensure that the samples they collect are properly labeled and stored in a secure environment.
