Answer:

Colchicine inhibits the formation of the microtubules or spindle fibers. Without the spindle fibers the chromosomes cannot move to the poles.

Explanation:

Spindles and microtubules are both important components of cellular division. The structures go hand in hand with each other and are necessary for cellular division to occur.

Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle and it is called meiotic spindle during meiosis,

Why are single-stranded binding proteins necessary for DNA replication?
Margarita [4]

Answer:

d.They prevent the two parental strands from coming together again.

Explanation:

During the process of DNA replication, the two DNA strands should be separated from each other to serve as a template. To separate the two DNA strands, the helicase enzyme breaks down the hydrogen bonds between the complementary base pairs of the DNA strands. The process uses ATP as a source of energy.

Due to the presence of complementary base pairs, the separated DNA strands have a tendency to reanneal by the formation of hydrogen bonds. To prevent the reannealing of separated DNA strands, single stranded binding proteins bind to them. Binding to single stranded binding proteins to the separated DNA strands does not allow them to reanneal.

Umnica [9.8K]

Answer:

Principle of cross-cutting relationships

Explanation:

The geologic principle that will provide the most profound explanation to this problem is the principle of cross-cutting relationships.

It states that "features that cross-cuts rocks are younger than the layer they cut through".

Some of these features are intrusions, faults and joints.

The logic behind this reasoning is that without the rock in place, the cross-cutting event wouldn't have been recorded.

We can liken this to a fracture on the wall of a building. If the wall is not erected, there wouldn't be any fracture. Therefore, the fracture is far younger than the wall.
