Lysogenic infections require a virus to insert its nucleic acid into a host cell's DNA, therefore the answer would be D
Answer:
The only mutations that matter to large-scale evolution are those that can be passed on to offspring . These occur in reproductive cells like eggs and sperm and are called germ line mutations . A single germ line mutation can have a range of effects : No change occurs in phenotype.
Explanation:
Then, what is the question ???
Answer:
D) A and C
Explanation:
Gram staining is a laboratory technique used for bacterial species. It is used to differentiate between two groups of bacteria based on the components of their cell wall. Gram staining was developed by a scientist called Christian Gram in the year 1884. In the gram stain procedure, the following occurs:
- Due to the thick peptidoglycan component of their cell wall, GRAM POSITIVE bacteria retains the crystal violet due and stain VIOLET.
- On the contrary, due to the thin peptidoglycan component of their cell wall, GRAM NEGATIVE bacteria do not retain the crystal violet dye and hence stain, RED.
Based on this, a bacteria that has been gram stained has been tested for its GRAM REACTION and microscopic morphological characteristics, since it is a microbe.
