Answer: Option C) A sentence in the instruction book
Explanation:
A gene is a specific portion on the DNA that code for a functional protein. i.e DNA consists of several genes, and some non-coding sequences that are usually spliced off during post-translational modification.
In other words, a gene can be best described as each single, meaningful sentence in the instruction book for building an organism.
Answer:
Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security, and medical benefits to the world's growing population.
Answer:
Genetic drift decreases the genetic diversity within a specie's population. Genetic drift is a change in the allele frequencies due entirely to random chance and probability and is more likely to affect smaller populations and groups than larger ones. Genetic drift can also play a role in the development of a new species.
