Two Core Techniques in Modern Biotechnology — NEET Biology

Which of the following statements correctly highlights the distinction between genetic engineering and traditional hybridisation methods? S1: Traditional hybridisation frequently results in the unwanted introduction and multiplication of undesirable genes alongside desired ones. S2: Genetic engineering is advantageous over traditional hybridisation primarily because it enables the precise introduction of only a single desirable gene or a specific set of genes. S3: One of the core techniques of modern biotechnology, bioprocess engineering, is solely focused on altering the chemistry of genetic material. S4: A key conceptual development of genetic engineering is that it allows the creation of recombinant DNA, gene cloning, and gene transfer. S5: Sexual reproduction, unlike asexual reproduction, preserves genetic information with minimal variation, which is a limitation overcome by genetic engineering.
