DanielleElmas [232]

Answer:

All living things are made of cells

Cells form from previously existing cells

Explanation:

According to the Cell Theory, all forms of life are composed of one or more cells, whereby cells are the fundamental building blocks in all living organisms. All cells are composed of inorganic molecules (e.g., water) and carbon-based organic molecules (e.g., carbohydrates, lipids, nucleic acids, etc). All the new cells arise from the division of pre-existing cells. Louis Pasteur showed cells would only grow in broth if they are exposed to air (oxygen), thus refuting the idea of spontaneous generation. In multicellular eukaryotic organisms, these cells can be organized in tissues, organs and organ systems.

How does a single change in nitrogen base alter the formation of a protein
jasenka [17]


During translation to RNA, the nitrogen bases on the DNA molecule are translated to complementary RNA bases. Afterwards, these bases are again used to form amino acids.
Three bases make up a codon, which codes for a specific amino acid. If a base is changed, the codon will become changed. This will result in a different amino acid being produced in and the primary structure of the polypeptide will be altered.
