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

True or false? cell death normally does not occur unless there has been an injury to the cell.
Evgen [1.6K]

The statement 'cell death normally does not occur unless there has been an injury to the cell' is false.

A cell can be described as the basic building block of life. All living organisms are known to be made of cells.

There are various reasons that a cell might die. A cell might die when its function is over. A cell might also die for the formation of other structures in the body. For example, the formation of an outer layer of the skin requires dead cells. A cell might kill itself if it has no use or finds that it has been invaded by an antigen.

Hence, the statement that cell death occurs only due to injury is false as cell death can occur due to various other reasons.
