Answer:
The features of prokaryotes include circular DNA molecules and small ribosomes.
Explanation:
Prokaryotes are organisms having only one cell (unicellular). In their cells, an organized nucleus is absent along with other membrane-bound organelles. Examples include bacteria and archaea. The prokaryotic cell mainly consists of the plasma membrane, cytoplasm, DNA and ribosomes. Some prokaryotes have special structures such as flagella, pili, fimbriae, etc. Flagella help in the locomotion and pili or fimbriae are used for the attachment to host cells and other surfaces.
Their cells contain large quantities of genetic material (DNA and RNA). A single, large circular strand of DNA is found in the central part of the cell (nucleoid) and contains most of the genes. The ribosomes found in prokaryotes are smaller in size. A large number of ribosomes are present inside a prokaryotic cell. The shape and composition of ribosomes are slightly different than those in eukaryotic cells.
Organelles float around in the cytoplasm.
That is called an insertion mutation which is a type of a frameshift mutation
depending on where you put the extra nucleotide, the amino acid sequence may look different.
Answer:
Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration. Anaerobic respiration evolved prior to aerobic respiration.
