Question

Which two cell structures work together in the

Answer 1

Answer:

The most appropriate answer would be (3) nucleus and ribosome.

A nucleus is the controlling center of the cell which contains genetic material of the cell that is, deoxyribonucleic acid (DNA). DNA codes for mRNA (messenger ribonucleic acid) which carries the codes for protein synthesis from DNA (nucleus) to the ribosomes.

Ribosome forms the site for protein synthesis in the cell. Ribosome forms the complex around the initiation codon of the mRNA and then moves along the length of mRNA.

As ribosome moves, tRNA (transfer RNA) keeps adding specific amino acids to the growing polypeptide chain according to the codon sequence of mRNA.

Ribosome releases the mRNA and newly synthesized polypeptide chain as soon as it reaches the termination codon of the mRNA.

Answer 2

The answer is (3) nucleus and ribosome. Mitochondrion is responsible for cell respiration and chloroplast is responsible for photosynthesis. Vacuole is responsible for electrolyte balance in plant cell.
