The domestic cat genome contains 2.9×109 base pairs. The length of linker DNA in mammals is 50 base pairs. Approximately how man

IgorLugansk [536]

Answer:

Number of nucleosomes in $2.9 * 10^9$ bp 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

$= 146 + 50\\= 196$ bp

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

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

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

2. auxins (chemicals produced in plants that are characterized by their ability to induce cell elongation and cell division in stems)
3. cytokinins (chemicals that helps plant cells divide)

4. ethylene (a hormone that promotes ripening of fruit or blooming of flowers)

5. gibberellins (chemicals produced by plants that stimulate stem elongation, seed germination, and flowering)

Reactive or evocative correlation. An example would be a child that shows particular interest and talent to sports. The parents are not particularly inclined to sports and grew up not playing them, but provides the child with opportunities to play and practice them. This action by the parents reinforces the child's genetic tendency to sports.
