Answer:

The RNA helps in the determination of the sequence of amino acids in proteins and polypeptides by a two-step procedure, that is, the transcription of DNA, which generates mRNA in the nucleus, and the translation of the mRNA to tRNA occurring at the ribosome in the cytoplasm.

The association of ribosomal RNA takes place with a set of proteins to produce ribosomes. These composite structures move physically along the molecule of mRNA and catalyze the arrangement of amino acids into protein chains. They also associate with tRNAs and different other accessory molecules that play an essential role in the synthesis of protein.

At some point in their life cycle, all cells have a _____, whereas not all cells have a(n) _____.

Shtirlitz [24]

The cell membrane is present during the whole cycle. The nuclear cell breaks and then is regenerated. At some point in their life cycle, all cells have a _cell membrane_, whereas not all cells have a(n) _nuclear cell_.

<h3>What happens to the membrane during cell cycle?</h3>

The cell cycle involves two stages. First occurs the interphase, and after that cell division. During the interphase, the cell prepares for division, duplicating its size, its content, and genetic material.

During the prophase, the nuclear membrane breaks. Cell division occurs (either mitosis or meiosis), and at the end of the cycle, the nuclear membrane regenerates again (during the telophase).

Finally, cytokinesis occurs in which through invagination of the cell membrane, the cell divides into new cells.

The cell membrane is present during the whole cycle, protecting the cell content. The nuclear cell breaks and then is regenerated.

At some point in their life cycle, all cells have a _cell membrane_, whereas not all cells have a(n) _nuclear cell_.
