In 1970, Hamilton Smith isolated the first restriction enzyme. Restriction enzymes are used to cut strands of DNA at specific po

ints. This discovery led to the development of recombinant DNA, which is widely used in several scientific industries to produce proteins and hormones more cheaply and in much larger quantities than earlier methods. The change in scientific knowledge caused by Smith’s discovery most directly affected which sector of society?
A technology

Answer:

The correct answer is A. technology.

Restriction enzymes are the class of enzymes used to create a nick in DNA strand. They cleave the DNA at or near a specific base sequence which is called as restriction site.

It leaded to the advancement in recombinant-DNA technology. Restriction enzymes made it possible for the scientists to make a recombinant DNA at that time. These enzymes help in creating the nick in a DNA at the desired position as well as in the production of sticky ends. At this desired position, the scientist then inset the gene of interest.

Recombinant-DNA (rDNA) technology enabled the scientists to produce insulin, penicillin, genomic libraries etc.

What affects algal growth with increasing depth in the ocean?
andrew-mc [135]
The answer is light.

One of the factors that affect photosynthesis is light. Without light, the photosynthetic rate is reduced or even stopped which consequently affect algal growth. With increasing depth in the ocean, there is less sunlight present. Still, a<span>lgae have accessory photosynthetic plastids other than the chloroplasts</span><span> that can absorb different light in greater ocean depths. This helps them to maximum use sunlight in such conditions. But, in the end, at some particular depth, they would not be able to survive.</span>
