Stem cells are important to multicellular organisms because of their
Lina20 [59]

Answer:

ability to differentiate into other cell types during cell division i.e. totipotent nature

Explanation:

Stem cells are undifferentiated cells with the unique ability to develop into specialized cell types in the body during early life and growth through the process of cellular differentiation. When a stem cell divides, each new cell has the potential to either to remain a stem cell or become another type of cell with a more specialized function e.g muscle cell, red blood cell or a brain cell.

Stem cells provide new cells for the body as it grows, and replace specialized cells that are damaged or lost. This ability of stem cells to differentiate into a variety of cell types in an organism including embryonic tissue, is an important distinguishing factor. They have two unique properties that enable them do so:

1. They can divide over and over to produce new cells

2. As they divide, they can change into the other types of cell (cellular differentiation).

What technique did Hershey and Chase use in their experiment that led to the conclusion that DNA, not protein, was the genetic m
Olenka [21]

Answer:

They used radioactive labeling techniques to build two different types of phage.

Explanation:

In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.

Suppose you discover a new form of a nucleic acid, XNA. Like DNA, it is double-stranded. You are interested in its mode of repli
victus00 [196]

Answer:

A: Unlike DNA, XNA replicates conservatively

Explanation:

<em>The replication of the DNA is </em><em>semi conservative.</em><em> This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.</em>

In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.

Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.
