The cell is the smallest unit of living material capable of carrying on all activities necessary for life. ... Only animal cells are without a cell wall. Protoplast is the living part of the cell inside the cell wall and includes the cell membrane and the protoplasm.
The meselson-stahl experiment demonstrated that dna replication produces two DNA molecules each composed of the nitrogen isotopes.
<h3>
What was the conclusion of the meselson-stahl experiment?</h3>
Based on observations and experimental results, Meselson and Stahl concluded that DNA molecules can reflect semi-conservatively. Investigation of semi-conservative nature of replication of DNA or the copying of the cells, DNA failed to cease there.
1958, Matthew Meselson and Franklin Stahl carried out an test on E. coli which divides in 20 minutes, to take a look at the replication of DNA. 15N (heavy) and 14N (normal) are isotopes of nitrogen, which may be outstanding primarily based totally on their densities through centrifugation in Caesium chloride (CsCl).

Explanation:
a fungus named penicillin produces a substance that kills the bacteria near it. The mold produces the antibiotic penicillin. How do fungi help plants grow? The hyphae spread underground and absorb water and nutrients from the soil for the plant.

Answer:
b. involves synthesizing the peptide and then attaching it to a solid support
the amino acid is reacted with a molecule known as a "linkage agent" that enables it to attach to a solid polymer, and the other end of the linkage agent is reacted with the polymer support (insoluble)
