How do restriction enzymes precisely cut bacterial plasmids to produce "sticky ends"? Make sure you discuss how the restriction enzyme identifies the target DNA sequence in the plasmid and name the enzyme that "cuts" the DNA.

Answers

A 'sticky' end is produced when the restriction enzyme cuts at one end of the sequence, between two bases on the same strand, then cuts on the opposite end of the complementary strand. This will produce two ends of DNA that will have some nucleotides without any complementary bases.Answer:

Which of the following is NOT true about energy balance? A. Energy balance is influenced by the amount of exercise one gets and their dietary habits. B. Inactive people use more energy so they should consume fewer calories. C. Stored body fat will increase if calorie intake is greater than energy used. D. Energy balance is the balance between the amount of calories consumed and the amount used for energy.

Answers

The option C, which is, Inactive people use more energy so they should consume fewer calories is not true about energy balance.  

Energy balance refers to the relationship between the energy in and energy out. Energy balance is affected by the amount of exercise one gets and their dietary habits. Stored body fat will increase if calorie intake is greater than the energy used.

Stored body fat will increase if calorie intake is greater than the energy used. Energy balance is the balance between the number of calories consumed and the amount of energy used.


The difference between the number of calories consumed and burned each day is energy balance. An inactive person uses less energy as compared to an active person due to less work out and therefore would require fewer calories.

Further Explanation:

The difference between input and output energy or calories is the energy balance of the body. The energy balance can be categorized as;

a) Perfect balance: In the energy equation if the input and output difference in energy comes out to be zero, then one has a perfect energy balance. This means neither weight is lost nor gained. During the weight loss journey, the people in their weight maintenance stage show perfect energy balance.

b) Positive energy balance: If the difference in the energy input and output results in a positive number, a person gains weight. The people like growing children, weightlifters, and pregnant women show positive energy balance and bulk up.

c) Negative energy balance: If the difference ends up in a negative number, a person achieves an imbalance required for weight loss. This is called energy deficit and the person slims down due to the negative energy difference and loss of calories.

An active person uses more of its consumed energy to perform physical activities and hence would consume more calories to keep the body at its pace. Whereas, an inactive person do little or no physical activities and therefore requires less energy. As a result, he/she would consume fewer calories due to low energy requirements.
