For translation to take place, which of the following would not be required to be present? 1. DNA.
2. mRNA.
3. tRNA-amino acid complex.
4. rRNA.

The correct answer is 1. DNA would not be required to be present.

Explanation:

Translation takes place in ribosomes, in a very similar way in prokaryotes and eukaryotes, starting with a start codon and ending with a stop codon. The messenger RNA is the one that carries the information for protein synthesis, that is, it determines the order in which the amino acids will be joined. Ribosomes are made up of two functional subunits of different sizes that associate or dissociate throughout the biosynthetic process. In addition to ribosomes, a series of protein translation factors also participate in the process, interacting with aminoacyl-tRNA molecules, ribosomes and mRNA to carry out the translation process with precision. The amino acids are transported by the transfer RNA, specific for each one of them, and are taken to the messenger RNA, where the codon of the latter and the anticodon of the transfer RNA are paired, by complementarity of bases, and in this way they are they place themselves in the position that corresponds to them. Once the synthesis of a protein is finished, the messenger RNA is free and can be read again.
