lys-0071 [83]

Answer:

sweepstake route

Explanation:

From the view of the horses, the ocean barrier would be seen as a  <u>sweepstake route</u>.

<em>By definition, the sweepstake route refers to a rather difficult or dangerous path through which animals can move from one place to another. No animal would take this path ordinarily except by pure chance or when events leave no other option.</em>

In the illustration, no horse would engage in an adventure of swimming across the ocean to North America until the European settlers decided to ferry them across. Hence, to the horses, the ocean barrier represents a sweepstake route.

What do scientists hope to accomplish using recombinant DNA?
Ber [7]

The correct answer is: Replacement of defective genes with normal genes

Recombinant DNA molecules are made in laboratory by the methods of genetic recombination such as molecular cloning. The aim of these methods is to bring together genetic material from different sources, creating “combinations” that usually couldn’t be found in the genome. The process of recombination is possible because, DNA molecules from all organisms share the same chemical structure (nucleotides are same among different species, difference is only in the nucleotide sequence).
