Diploid refers to a cell that has two copies of each chromosome. One way that a diploid organism could have an offspring that are 3n (triploid) or 4n is when the chromosomes don't separate during meiosis.

Triploid refers to some cell that have 3 copies of each chromosomes for a total of 69 chromosomes.

Answer:

Popypoidy mainly occurs in the plants when there is total non-disjunction of sister chromatids occurs during the meiosis of gametic cells. So as before the meiosis the number of chromosomes doubles and after meiosis every cell get half the number of chromosome so after segregation failure autopolyploidy occurs in plants.

Triploid condition can also be seen in animals when two sperms fertilize one ovum. So, in this case, the chromosome number reaches to 69(23+23+23) which means chromosome number become 3n.

Airida [17]

Answer:

48 hours

Explanation:

Patch testing is a method to test the allergic reactions called contact dermatitis caused by the allergens found in the environment the patient is surrounded by like home allergens or work allergens.

To perform the test, the allergens are placed on the metal discs which are pasted on the back of the person with hypoallergenic tape.

Then the discs are allowed to be pasted on the back of the person for about 2 days or 48 hours after which the skin is examined for the allergy reactions caused by an allergen in the form of inflammatory response or hypersensitivity.

Which of the following sets of materials is required by both eukaryotes and prokaryotes for replication? Group of answer choices

erastova [34]

Answer:

Double-stranded DNA.

Explanation:

Replication may be defined as the process of formation of the daughter DNA from the parent DNA with the help of enzymes and proteins. The three main process of replication are inititation , elongation and termination.

The double stranded DNA molecule undergoes the process of replication. Four different dNTPs - adenine, guanine, thymine and cytosine are required for the process of replication. Primers are required for initiation of the process of replication and ori region is the inititaion point of replication.

Thus, the correct answer is option (a).
