Answer:
How does a bacterial cell protect its own DNA from restriction enzymes?
B. by adding methyl groups to adenines and cytosines
Explanation:
The restriction modification system is for the cells defense mechanism. This system is composed of a restriction endonuclease enzyme and a methylase enzyme and each bacterial species and strain has their own combination of restriction and methylating enzymes.
Bacteria have restriction enzymes, also called restriction endonucleases, which cut double stranded DNA at specific points into fragments. This restriction enzymes don’t cleave the bacteria's own DNA because restriction enzymes do not exist in the bacterial DNA sequence.
But is if the recognition sequences exist but the enzyme is methylation specific. Bacteria prevent their own DNA from chop down by restriction enzyme through methylation of the restriction sites. Methylation of DNA is a very familiar way to modify DNA function and bacterial DNA is highly methylated.
Regrowth of grasses, ferns, wildflowers, and saplings after a forest fire is an example of secondary succession.
Secondary succession is one of the two main forms of ecological succession of plant life that is initiated by an occurrence such as harvesting, or forest fire, that has a negative impact or diminishes an already established ecosystem such as a forest or a wheat field to a lower number of species. Several factors such as initial composition, trophic interaction, and competition-colonization trade-offs can influence secondary succession.
B. Spermatogenesis.
Make gametes are called sperm, and
Spermato-sperm
genesis-creation
Answer:I think it was The Heat waves can be dangerous, causing illnesses such as heat cramps and heat stroke, or even death. Warmer temperatures can also lead to a chain reaction of other changes around the world. That's because increasing air temperature also affects the oceans, weather patterns, snow and ice, and plants and animals
