Which of the following was the major contribution made by Avery, MacLeod, and McCarty that strengthened the argument that the tr
galben [10]

The major contribution made by Avery, MacLeod, and McCarty was 'transformation of nonvirulent cells with a DNA extract was blocked only if DNase was added'. This observation supported the idea that the transforming agent in Griffith's experiment was DNA.

The Avery–MacLeod–McCarty experiment showed that DNA was the transforming agent observed in Griffith's experiment.

Griffith's experiment (1928) suggested that bacteria were capable of transferring genetic information (DNA) by a process of horizontal gene transfer called transformation.

While the bacteria were killed by heat, Frederick Griffith observed that the DNA had was taken up by II-R strain bacteria via transformation.

Avery–MacLeod–McCarty experiment observed that protease enzymes did not destroy the transforming agent (but DNAse destroyed this transforming principle), thereby suggesting that the transforming agent in Griffith's experiment was bacterial DNA.

IgorLugansk [536]

Answer:

Number of nucleosomes in 2.9 * 10^9bp is equal to 1.47 * 10^7

Explanation:

For wounding one nucleosome, total length of DNA required is equal to 146 bp

The length of  linker DNA in mammals is equal to 50 bp

Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length

= 146 + 50\\= 196bp

Thus, in 196bp length of DNA, the total number of nucleosomes is equal to 1

Thus, number of nucleosomes in 2.9 * 10^9bp is equal to

\frac{2.9* 10^9}{196} \\1.47 * 10^7
