Misha Larkins [42]

Answer:

a. conservative replication

b. semi conservative replication

c. dispersive replication

d. discontinuous replication

e. continuous replication

The CORRECT ANSWER IS C.

c. dispersive replication

Explanation:

The attached image shows a single band that becomes lighter (in volume) and increase in darker intensity (in times of color) is revealed with consecutive replications. The major pattern that would produce these outcome is dispersive replication.

Conservative replication do reveal two bands (a 14N for the wholly latest molecule, and a 15N for the totally antiquated molecule) after the initial replication. Therefore, this wholly wrong.

Semi-conservative replication reveal an individual band of transitional weight after the initial  replication, followed by two bands following the second replication (one of transitional weight, and the other at the 14N position). These two bands is observed in each following replication, with the transitional weight becoming lighter in color as the 14N band is seen to appear darker in color.

The real pattern gives an individual band that pinpoints to all molecules in an individual replicative cycle possessing the same constituents.

Dispersive replication, has its molecules to be a blend of old (15N) and new (14N) strands. Each replication raises the ratio of new to old strands as it explains the reason an individual band is shown raised (lighter in weight) with every replication.

Each daughter cell resulting from mitotic cell division has exactly the same genetic composition. Select one: True False
sveta [45]

Answer: True

Explanation: The importance of mitotic cell division is to produce two daughter cells that are genetically identical. The genetic materials of the parent cell are arranged and moved towards the two spindle poles with the help of the spindles so that there will be an even distribution of the parent cell's genetic materials between the resulting two daughter cells.

Linked genes are genes that Select one: a. assort independently. b. segregate equally in the gametes during meiosis. c. always c
nexus9112 [7]

Answer:

d. are found on the same chromosome

Explanation:

Linked genes are genes that <em>sit close together on the same chromosome,</em> this closeness makes higher the probability to inherit them together, meaning they won't follow Mendelian inheritance. Considering this information we can conclude that the correct answer is d. are found on the same chromosome.

I hope you find this information useful and interesting! Good luck!
