STANDARD Botany Recognition Sequences MCQ Question

The specific base sequence where molecular scissors, such as restriction enzymes, work is known as the recognition sequence, making option A the correct choice. These enzymes identify and bind to specific nucleotide sequences in DNA to cut it at precise locations. Option B, antibiotic resistance, refers to the ability of bacteria to withstand the effects of antibiotics and is unrelated to molecular scissors. Option C, the sigma factor site, pertains to bacterial transcription initiation, while option D, ORI (origin of replication), is the specific site where DNA replication begins, not where molecular scissors act.
