Alex777 [14]

Answer:

3rd generation = 2 Hybrid DNA molecules + 6 Light DNA

In Percentage 2÷8 × 100 = 25%

25% of the DNA are hybrid

Explanation:

Semi conservative model proposed by Watson and Crick states that one strand of the DNA comes from parent DNA which act as a template for the other newly formed strand.

First generation:

If cells containing 15 N DNA are transferred to a medium with only 14 N then in initial first generation two parent strands becomes separated and act as template for newly synthesized strands. this means that in first generation both DNA molecules are hybrid, one strand of 15 N DNA and other strand of 14 N DNA

Ist generation = 2 Hybrid DNA molecules

Second generation:

In Second generation these two hybrid molecules become unzip. Two strands are 15N and two strands are 14N. All these 4 strands act as template and 4 new strands are synthesized. The molecules of Hybrid DNA is still 2 with 2 molecules of Light DNA.

2nd generation = 2 Hybrid DNA molecules + 2 Light DNA

Third generation:

In Third generation these two hybrid molecules and two light DNA molecules become unzip. Two strands are of 15N and six strands are of 14N. All these 8 strands act as template and 8 new strands are synthesized. The molecules of Hybrid DNA is still 2 with 6 molecules of Light DNA.

3rd generation = 2 Hybrid DNA molecules + 6 Light DNA

In Percentage 2÷8 × 100 = 25%

25% of the DNA are hybrid

Is plate-based or a meat-based diet is more nutritious
seropon [69]
Question: is plate-based or a meat-based diet is more nutritious

Answer: But it's also common to choose a plant-based diet because it's considered healthier. And that's for good reason. Research over many years has linked plant-based diets to lower rates of heart disease, type 2 diabetes, and some cancers (as compared with diets high in meat and other animal products

Is a meat based diet better than a plant-based diet? Answer: Mounting evidence shows that reducing meat and increasing plant-based protein is a healthier way to go. A diet with any type of meat raises the risk of heart disease and cancer, when compared with a vegetarian diet.”

Plant-based diet: A plant-based diet or a plant-rich diet is a diet consisting mostly or entirely of plant-based foods. Plant-based foods are foods derived from plants with no animal-source foods or artificial ingredients. While a plant-based diet avoids or has limited animal products, it is not necessarily vegan.

Meat based diet:

Meat is a complete, high-quality protein containing all of the essential amino acids your body needs for optimal health.


Meat provides more protein per serving (25 grams per 3 ounces) than dairy (8 grams per cup), eggs (6 grams each), legumes (12 grams per ¾ cup), vegetables or nuts (2 to 5 grams per serving).
