Some food crops are difficult to grow for a variety of reasons.For example,strawberries are easily susceptible to frost damage.How could one use genetic engineering techniques help to overcome this type of problem,and which type of animal or plant would one look to for help?
A)To increase the frost hardiness of strawberries,one could generate a strain of transgenic strawberries using a gene that confers frost resistance.To identify such a gene,one could look to an animal or plant that lives in a very cold environment.Such organisms are likely to have some form of natural protection against frost.
B)To increase the frost hardiness of strawberries,one could generate a strain of cloned strawberries using a gene from another plant that confers frost resistance.
C)To increase the frost hardiness of strawberries,one could generate a strain of strawberries using a breeding design that confers frost resistance.By beginning with northern strawberry strains,breeding and selecting those that survive colder temperatures would eventually produce frost hardiness.

Option A suggests using genetic engineering techniques to generate a strain of transgenic strawberries with a gene that confers frost resistance. To identify such a gene, one could look to an animal or plant that lives in a very cold environment. Thus, option A presents a viable solution to overcome the difficulty of growing strawberries in frost-prone areas. Option B suggests using cloned strawberries, which may not be a feasible solution, as it may not confer frost resistance. Option C suggests a breeding design but may take longer to produce frost-hardy strawberries compared to using genetic engineering techniques. Hence, option A is the best choice.
