What are the base pairs in DNA and RNA?

2 answers:

7 0

Although very similar, the base pairs in DNA and RNA differ by one nitrogenous base.

In DNA, the four nitrogenous bases are Adenine, Thymine, Guanine, and Cytosine. Adenine always bonds to thymine (in DNA), they are connected by two Hydrogen bonds. Cytosine and Guanine are always bonded together. They are connected by three Hydrogen bonds.

However, in RNA, there is no thymine and instead, there is Uracil. That is the only nitrogenous base that is different. Cytosine still bonds to guanine, and adenine bonds to uracil.

I hope that helps!

Every nucleotide in the coding strand has a complementary nucleotide in the other strand, called the template strand. The Watson-Crick pairs are the standard DNA and RNA base pairs. In DNA, adenine bonds to thymine while guanine bonds with cytosine. The same pairs apply to RNA, except that uracil replaces thymine.

Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answe

Ratling [72]

Answer:

The Harris Benedict Equation is a formula that determines the total daily energy expenditure (calories) using BMR with some activity factors.

Basal Metabolic Rate (BMR) is defined as the amount of calories one would burn without doing anything for 24 hours. It uses variables of weight, age, height and gender to calculate BMR.

BMR calculation = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)

In Harris Benedict Equation, BMR is multiplied by activity factor to determine calories need.

The activity factors in Harris Benedict Equation are:

for no exercise = 1.2

exercise for 1 to 3 days/week or light exercise = 1.375

exercise for 3-5 days/week or moderate exercise = 1.55

exercise for 6-7 days a week or hard exercise = 1.725

exercise for 2 times training = 1.9

So, calculation for my calorie needs is as following:

BMR = 447.593 + (9.247 x 50 kg) + (3.098 x 164.592 cm) - (4.330 x 23 in years) = 974.945

Calorie needs = BMR x 1.55

= 974.945 x 1.55

= 1511.16 calories

fgiga [73]

Answer:

Explanation:

Cooling reduces the excitement of the molecules of the DNA hence allowing the hydrogen bonds between the base pairs of the two strands to form hence the DNA is considered to anneal. Heating disrupts the hydrogen bonds and causes the two strands to dissociate.

Which of the following substances would have the most trouble crossing a biological membrane by diffusing through the lipid bila

tangare [24]

<h3>Answer;</h3>

d. Na+

<h3>Explanation;</h3>

The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others.
Small molecules that are non-polar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.
Charged ions such as N+ and K+ Cannot permeate the cell membrane for the since uncharged molecules repel uncharged molecules present in the membrane structure.
