"Mathew Meselson and Franklin Stahl performed classic experiments that supported semiconservative nature of DNA replication in 1985."

A band of hybrid 14N and 15N DNA was produced as a result of the DNA's initial duplication in a 14N medium. The conservative replication mode was so abandoned. "Based on their observations and experimental results, Meselson and Stahl concluded that DNA molecules can replicate semi-conservatively."

One original DNA serves as a template for the production of two DNA copies during conservative replication. One of these two is made entirely of fresh DNA, while the other is made of strands from old DNA. In semiconservative replication, the parent strand is used to make two copies of the DNA, each of which contains one original strand and the other new strand.

Most people think babies are equally likely to come as either a boy or a girl. This is not true. Actually, about 51.3% of all ba
kherson [118]

Answer:

26.3 %

Explanation:

In the given question,

The probability of boys is given that is - 51.3%

Therefore the probability of girls will be = 100- 51.3

                                                                  = 49.7%

The 51.3% probability of boys per thousand individual can be expressed as 513/1000= 0.513 P(B)

The 49.7% probability of girls per thousand individuals can be expressed as 497/1000= 0.497 P(G)

Now to calculate the probability that the first ans second child both are boys

We will fuse formula= P(B) x P(B)

                                 =    0.513 x  0.513

                                  = 0.263

Thus, 26.3 % is correct.

Doss [256]
The function of Mitochondria is in the generation of metabolic energy in eukaryotic cells. Mitochondria are responsible for most of the useful energy derived from carbohydrates and fatty acids. Assembly of Mitochondria thus involves protein encoded by their own genomes and translated within the organelle.
