Addition of a nucleotide onto a dna strand is an endergonic reaction. what provides the energy to drive the reaction?

Biology

Kruka [31]2 years ago

The release of pyrophosphate from the incoming nucleotide, and then hydrolysis of the pyrophosphate to inorganic phosphate provides energy for the addition of nucleotide onto a DNA strand.

Nucleotides are linked together by a condensation event that yields a tiny, stable molecule. But the released molecule is pyrophosphate, not water. A good amount of free energy is released when water is added to pyrophosphate.

The high-energy link between the ejected beta and gamma phosphates stores the energy for each incoming nucleotide's addition. The subsequent hydrolysis that occurs drives the process. A substantially greater quantity of energy is released when two phosphates are separated into individual phosphates.

Anika [276]

Answer:

In favourable environments you might find birds laying more eggs, and a greater likelihood of multiple successful clutches. There are also birds like Bald Eagles, that start mating in early January and can lay eggs before Spring officially comes. 13. Food Availability. The amount of food available has an affect on bird mating cycles.

Exercising causing ___________
goldfiish [28.3K]

Answer:

c. increase HDL levels

Explanation:

Cholesterol is carried in blood in two ways, LDL and HDL. Both of them are lipoproteins made of fat and protein. LDL or Low Density Lipoprotein has 50% cholesterol and 25% protein by weight. HDL or High Density Lipoprotein has 20% cholesterol and 50 % protein. LDL carries cholesterol to arteries and deposits it there which is not good for the body. HDL on the other hand removes excess cholesterol from body via liver.

Aerobic exercise increases HDL values and lowers LDL values. It has been shown that exercising regularly can increase HDL level by 6% which is good for the overall health of the body. For maximum effect 30 minutes of moderate exercise should be done 5 times a week.

Una carga de 50 N unida a un resorte que cuelga verticalmente estira el resorte 5cm. El resorte se coloca ahora horizontalmente
ELEN [110]

Answer:

-110 N

Explanation:

Una carga de 50 N unida a un resorte que cuelga verticalmente estira el resorte 5cm. El resorte se coloca ahora horizontalmente sobre una masa y se estira 11cm. ¿Qué fuerza se requiere para estirar ese resorte en esa cantidad?

Solution:

La constante de resorte (k) es la relación entre la fuerza (F) y la extensión (d) como resultado de la fuerza aplicada, por lo tanto:

k = F / d

Dado que F = 50 N, d = 5 cm = 0.05 m. Por eso:

k = F / d = 50 N / 0.05 = 1000 N / m

La fuerza (F) requerida para provocar un estiramiento de 11 cm se da como:

F = -kx

x = 11 cm = 0,11 m. Por eso:

F = -kx = -1000 * 0,11 = -110 N

El signo negativo significa que el objeto se tira hacia el resorte.
