Detailed explanation-1: -Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.

Detailed explanation-2: -The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs. During translation, proteins are made using the information stored in the mRNA sequence. The mRNA attaches to a structure called a ribosome that can read the genetic information.

Detailed explanation-3: -Ribosomes receive information from the cell nucleus and construction materials from the cytoplasm. Ribosomes translate information encoded in messenger ribonucleic acid (mRNA). They link together specific amino acids to form polypeptides and they export these to the cytoplasm.

Detailed explanation-4: -Assertion : Replication and transcription occur in the nucleus but translation takes place in the cytoplasm. Reason : mRNA is transferred from the nucleus into cytoplasm where ribosomes and amino acids are available for protein synthesis.

Detailed explanation-5: -Ribosomes are mainly found bound to the endoplasmic reticulum and the nuclear envelope, as well as freely scattered throughout the cytoplasm, depending upon whether the cell is plant, animal, or bacteria.
