If mutation destroys the function of the Cas9 gene then the bacteria will not be able to target a specific bacteriophage for destruction upon infection for the second time.

<h3>What is the Cas9 gene?</h3>
  • Cas9 is a 160 kilodalton protein that plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids and is heavily utilized in genetic engineering applications.
  • Its main function is to cut DNA and thereby alter a cell's genome.
  • Although Cas9 is an endonuclease and is evolved as a mechanism of immunity against viruses, they are not considered restriction enzymes.

One oak tree cell with 14 chromosomes undergoes meiosis. How many cells will result from this process,???
Tomtit [17]

Answer:

Four (4) cells

Explanation:

Meiosis is the type of cell division in which four daughter cells that are genetically different is produced. The daughter cells are gametes that have undergone a reduction in their chromosome number (by half).

For example, one cell of an oak tree with 14 chromosomes is said to undergo meiosis. This means that, based on the explanation of meiosis above, the oak cell will give rise to four (4) daughter cells containing 7 chromosomes each.

If the theory of evolution were true it would not be possible to classify organisms into distinct categories.
Alenkinab [10]
TRUE!!!! Idk if this answer is actually for a quiz, but for my opinion and belief, it would be impossible to classify animals and organisms if all of this came from an accident. If this question is for a quiz though, I assume that they will expect you to say False. Mostly to defend their belief. So it's really up to you on what you're gonna go with.
