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: -During transcription, a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell. The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs.

Detailed explanation-3: -The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes.

Detailed explanation-4: -The first step in protein synthesis is transcription where an mRNA molecule is synthesized using DNA as template in the nucleus. The mRNA is then released into the cytoplasm where it is translated into a protein using ribosomes and tRNA.

Detailed explanation-5: -Export of mRNA from the nucleus to the cytoplasm takes place through a pore complex in the membrane of the nucleus. Export is believed to involve the attachment of an adapter protein to the mRNA.
