Answer:

Crossing true breeding plant

Explanation:

Gregor Mendel is known as the Father or Genetics as he was the first successful person to observes and study and understand the pattern of inheritance of traits in the population for which he selected the Pea plants.

He performed the experiment by crossing the plants with different varieties of traits like the color of the flower, shape and structure of pods and others.

He knew that which plant is responsible for the trait of the progeny as he grew the pure-breeding plants which when were self-fertilized produced the same traits as of their parent and when cross-fertilized determined the trait of the progeny.

Thus, Crossing true breeding plant is the correct answer.

After infection of a cell, a viral particle must transport itself to the nucleus in order to produce viral proteins. What is the
kykrilka [37]

Answer:

Double-stranded DNA

Explanation:

If a virus requires to transport its genome in the nucleus to produce viral protein then the viral genome content must be DNA. This DNA of the virus will use the RNA polymerase of the host cell and will first convert into mRNA in the nucleus.

Then the mRNA of the virus will come out of the nucleus because the protein synthesis takes place outside the nucleus and in the cytoplasm. So in the cytoplasm by using host translational machinery the viral mRNA will code for viral proteins. So the correct answer is double-stranded DNA.

What are the two main functions of mitosis?
Nikolay [14]

Mitosis helps in the growth by means of hyperplasia. It also helps in reproduction in single celled organisms.

Neuron and Red Blood Cells doesn't undergo cell division once formed.

Osteoblasts help in forming new bones and joining old ones after there's a fracture in bone.

<h3><u>Explanation:</u></h3>

Mitosis is the process by which a cell divides into two daughter cells. It helps in growth of multicellular organisms as well as reproduction in single celled organisms.

The Red blood cells are formed from the bone marrow megakaryocytes and never undergo mitosis. Same are the neurons which are formed from stem cells and never undergo cell division.

The osteoblasts come into action as the bone breaks. They diposit new calcium compounds between the broken part of bones. This leads to irregular growth of bones between them which is then remoulded and brought back to shape by osteoclasts and osteocytes.
