Summarize the experiment in which Griffith became aware that hereditary information could be transmitted between two organisms in an unusual manner.

Answers

Answer:

In his experiment, Griffith used two strains of Streptococcus pneumoniae type II- rough(R) strain and a type III smooth(S) strain. The type III smooth strain had an outer polysaccharide capsule which makes smooth strain a virulent strain.

So in his experiment, Griffith injected these strains in mice in an order and observed the result. When he

injected living S strain- Mice died

Injected living R- strain- Mice survived

Injected heat-killed S strain- Mice survived

Injected heat S strain+ living R strain- Mice died

So after his experiment, he concluded that R strain took something from heat killed S strain which transformed the R strain into virulent strain that killed the Mice. So based on this experiment Griffith gave transformation principle.

Mitochondria and other organelles are manufactured in mitosis or interphase?

Answers

Organelles are manufactured and separated in mitosis.

Final answer:

Mitochondria and other organelles are formed through cellular respiration, not in mitosis or interphase.

Explanation:

Mitochondria and other organelles are not manufactured in mitosis or interphase. They are actually formed through a process called cellular respiration. Mitochondria are responsible for producing ATP, the energy currency of the cell, through a series of chemical reactions. Other organelles, such as the endoplasmic reticulum and Golgi apparatus, are involved in the synthesis, processing, and transport of various molecules within the cell.
