Answer:

Unvaccinated person has naturally immune , cannot catched by this disease.

Explanation:

The white blood cells can recognise that these are not human protein . The invading or foreign protein is called an antigen . Antigen in the blood

starts the white cells making defence chemicals called antibodies. Some antibodies break up the antigens . This stops the antigen entering the body cells & makes it easier for the Phagocytes

to egulfs and digest antigens/pathogens & also

Lymphocytes produce antibodies to destroy pathogens.

Some bacteria produce toxins inside the body ,

Our white blood cells can also make antitoxins to

destroy the poison .

Antibodies and antitoxins help prevent microbes damaging the body . The help us fight off the. disease , giving us IMMUNITY to the disease.

Total nucleic acids are extracted from a culture of yeast cells and are then mixed with resin beads to which the polynucleotide
mr Goodwill [35]

The question is incomplete as it does not have the options which are:

(a)DNA (b)tRNA (c)rRNA (d)mRNA

Answer:

Option-mRNA

Explanation:

The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.

The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.

This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.

Thus, mRNA is correct.

Scientists isolate cells in various phases of the cell cycle. They find a group of cells that have times more dna than g1 phase
ratelena [41]

Answer:

in the S phase of the cell cycle

Explanation:

<em>Scientists isolate cells in various phases of the cell cycle. They find a group of cells that have 1.5 times more DNA than G1 phase cells. The cells of this group are _____.</em>

The cell cycle has two main stages which is the interphase and the M phase.

While the M phase is characterized by active division, the interphase consists of G0 phase which is entirely a resting phase for cells that do not need to divide ordinarily, G1 phase which is a phase for cell drowth and development, S phase which is a phase for DNA synthesis or replication and G2 phase which is a phase for protein synthesis.

Hence, cells in the S phase and G2 phase of the cell cycle are expected to have more DNA than cells in the G0 and G1 phase.

<em>Essentially, the amount of DNA is doubled in the S phase. Therefore, if the cell group have 1.5 times more DNA than G1 phase cells, it means the cells are still in S phase.</em>
