The first two structures that combine during the process of translation are 1 and 4.
What is translation?
The translation is a biological process during which the genetic codes in transcribed DNA, in the form of messenger RNA, are translated to their respective amino acids and joined together by peptide bonds to form proteins.
The steps involved in the translation process are:
- mRNA binds to the small subunit of the ribosome
- tRNA carrying methionine binds to the start codon on the mRNA
- Large ribosome subunit binds to complete the translation complex.
In the image, mRNA is designated as 4 while tRNA is designated by 2. 1 is the ribosome while 3 is the synthesized protein.
Thus, the first two structure that binds is mRNA and tRNA. That will be 1 and 4.
