Detailed explanation-1: -Answer. Explanation: Translation occurs in the ribosomes after leaving the nucleus, and does not involve DNA molecules.

Detailed explanation-2: -The molecules involved in translation are mRNA, ribosomes, and tRNA. During translation, messenger RNA (mRNA) attaches to the ribosome. The ribosome reads the mRNA in groups of three nucleotides called codons. Each codon codes for one amino acid.

Detailed explanation-3: -The key components required for translation are mRNA, ribosomes, and transfer RNA (tRNA). During translation, mRNA nucleotide bases are read as codons of three bases. Each codon codes for a particular amino acid.

Detailed explanation-4: -During translation DNA is not directly involved in its process. DNA first gets transcribed to RNA to form the mRNA which then gets translated to form the amino acid chain. DNA is only used in the process of replication and transcription. In translation it has no direct role.

Detailed explanation-5: -Protein synthesis thus involves interactions between three types of RNA molecules (mRNA templates, tRNAs, and rRNAs), as well as various proteins that are required for translation.
