Answer:

Eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located. Eukaryotic cells also contain organelles, including mitochondria (cellular energy exchangers), a Golgi apparatus (secretory device), an endoplasmic reticulum (a canal-like system of membranes within the cell), and lysosomes (digestive apparatus within many cell types). There are several exceptions to this, however; for example, the absence of mitochondria and a nucleus in red blood cells and the lack of mitochondria in the oxymonad Monocercomonoides species.

Mutation

Explanation:

A mutation is any change in the nucleotide sequence of the genome of a particular organism. Mutations may be caused by errors during DNA replication or by exposure to environmental mutagenic factors (e.g., ultraviolet radiation, chemical agents, etc). Mutations can be deleterious, neutral or beneficial depending on the environment. When a beneficial mutation occurs in the germline, it may potentially be inherited and subsequently increase its frequency in the population.

How is protein synthesis different in prokaryotes and eukaryotes?
Viktor [21]

Answer:

The correct answer is option B

Explanation:

Translation is the process of synthesis of proteins from mRNA in organisms  and transcription is the process of synthesis of mRNA from DNA.

Both prokaryote and eukaryotes shows the presence of translation but both shows many differences in the process of protein synthesis like site of transcription and translation as in eukaryotes transcription takes place in nucleus while translation takes place in cytoplasm. Since prokaryote lacks the nucleus, both transcription and translation takes place in cytoplasm and lacks the process related to post-translational modifications due to which they take place at the same time.

Thus, option B  is the correct answer.
