Homonym: primers (Paint)
Primers are short strands of nucleic acid, typically made of DNA or RNA, that serve as a starting point for DNA synthesis. They are essential in various molecular biology techniques, such as polymerase chain reaction (PCR), where they bind to specific sequences of DNA to initiate replication. Primers ensure that the desired segment of DNA is amplified accurately and efficiently.
In addition to their role in PCR, primers are also used in DNA sequencing and gene cloning. By providing a complementary sequence for DNA polymerase to attach, primers help researchers study genetic material, diagnose diseases, and develop new therapies.
