Answer: <u>Genetic Modification of crop plants.</u>
Explanation:
Genetic modification alters the genome of an organisms through the use of biotechnological tools and advancements in molecular biology. Usually, DNA is swapped among organisms, and between species; this is called transgenes. These altered plants are usually called transgenic organisms.
Some plants can be modified in several ways to meet global food security needs. These include:
-drought tolerance-plants grow in arid conditions with minimal water
-increased yield- plants produce more crop per input
The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a "double helix," in the journal Nature.
