Answer:

As a result of the Hershey and Chase experiments, scientists believe

that the “transforming principle” is DNA.

Explanation:

Hershey and Chase determined that DNA, not protein, was the inherent material. They resolute that a defensive protein coat was molded everywhere the bacteriophage, but that the interior DNA is what discussed its capability to produce offspring inside a bacterium. Transformation occurs when one bacterium picks up free-floating DNA and incorporates it into its own genome. When scientists first observed this behavior, it seemed that genes were transforming one type of bacteria into another, so they concluded there must be a 'transforming principle' at work.

The complex of DNA and protein that makes up a eukaryotic chromosome is properly called <u>chromatin .</u>

<u></u>

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.

What is the chromatin and its function?

To create chromosomes, chromatin fibers are coiling and condensing.
Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.

What is chromatin in cell?

Chromosomes in eukaryotic cells are made of chromatin, a compound of DNA and proteins.
Nuclear DNA is extremely compressed and wrapped around nuclear proteins in order to fit inside the nucleus; it does not exist as free linear strands.

Where is chromatin found?

Chromatin is a genetic material or a macromolecule comprising DNA, RNA, and associated proteins, which constitute chromosomes in the nucleus of a eukaryotic cell.
This chromatin is located within the cell nucleus.

What benefits do plants with a smooth stem have? Does the stem type protect a plant?

gogolik [260]

<h3><u>Benefits of smooth stem over rough stem:</u></h3>

Smooth stem plants like guava, eucalyptus etc do have a smooth layer of bark over its stem that comes out as a skin when they shed their barks. Whereas most of the other plants like mango, banyan etc do have a rough corrugated layer of bark over their stem.

The smooth stem doesn’t let water to accumulate in the bark which can led to infections to the tree. It also doesn’t allow any seed to settle on bark that can led to growth of parasites. Thereby this smooth bark saves the trees from some of the probable harm to the tree.
