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
B commerce
C government
D education
Biology

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.

Suppose virus A has a viral genome of 19,000 bp, and 10,000,000,000 viruses are replicated in an infected individual in a single
Kitty [74]

Answer:

1 day.

Explanation:

From the given information:

The rate of mutation induced by RNA polymerase is:

\implies \dfrac{1}{10000}= 0.0001

Since the genome comprise of 19000 bp;

To complete a single replication, the viral cycle induce: = \dfrac{19000}{1000}

= 1.9 \ mutation \\ \\  \simeq 2 \  mutation

However, in a single day; 10,000,000,000 viruses are reported to be replicated.

Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

= \dfrac{10,000,000,000}{2} \\ \\ = \text{5000000000 \ mutations \ in \ a \ half \ day which is half} \\ \\ \text{ the given no of the replicated virus}

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.

Does the size of the parachute affect its flight?
lana66690 [7]
Independent Variable: flight
Dependent Variable: size of parachutes
Controlled Variables: precipitation, wind speed, person using parachute (weight), and the shape of the parachute.

The question is slightly broad; it does not specify whether the experiment focuses on the quality of the flight (stability in the air), speed of descent, or the distance it can travel. However, this is what I have come up with.

Of the components that make up one's total energy expenditure, which is controlled by the person?
Pachacha [2.7K]

Total daily energy expenditure (TDEE) represents calories burned vs calories consumed or the total number of calories you burn for energy each day. It consists of three main components:

1. Resting metabolic rate (RMR) or Basal metabolic rate (BMR)- It is the energy which is associated with the maintenance of major body functions.

<span>2. The thermic effect of activity (TEA) or <span>Activity thermogenesis- It is the </span>energy expenditure due to physical work, muscular activity or physical exercise and it is controlled by a person.</span>

<span>3. The thermic effect of feeding (TEF) or Thermogenic foods-It is the energy expenditure after several meals and<span> it refers to calories used to digest different kind of foods you eat.</span></span>
