Which of the following is a reason why sticky end producing restriction enzymes are preferred compared to blunt end ones?
anyanavicka [17]

Answer:

D) Because sticky ends can be temporarily held together by hydrogen bonding between the two strands.

Explanation:

Restriction enzymes cut the DNA at specific restriction sites and by the mechanism of action they can form two types of ends:

  • sticky ends-single-stranded overhangs are formed
  • blunt ends-without overhangs.

The main advantage of sticky ends (their overhangs) is that they can complementary bind to another overhand formed by the same restriction enzyme. So, for example in cloning, if the DNA of interest and plasmid vector are cut with the same restriction enzyme, that  forms sticky ends, fragment of DNA will fit into a bacterial plasmid in one direction.

On the other hand, blunt ends can be inserted into vector in both directions: head-to-tail or tail-to-head.

In three to five sentences, describe the advantages and disadvantages of these maps in modeling mitosis.
Nina [5.8K]

Modelling refers to using a diagrammatic representation to present a particular event or biological activity.

The two maps shown are very good for representing/modelling mitosis.

Advantages

  • They clearly lists the various steps involved in mitosis and as well included the process of cell division starting from the interphase stage (for the second diagram).
  • The M phase was also clearly explained in the first diagram.

Disadvantages

  • The first pictorial diagram had to labelling to depict the name of each particular phase and makes understanding difficult.
  • The second diagram fails to show pictorial representation of what could have exactly happened in each stage in the process of cell division.

Decomposers are important because they​
eimsori [14]

Answer:

Decomposers and scavengers break down dead plants and animals. They also break down the waste of other organisms. Decomposers are very important for any ecosystem because if they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
