Respuesta :
The correct answer is 3'–5'; 5'–3.
During trancription (process of formation of the mRNA from the DNA), the template strand or the non coding strand, which is present in the direction of the 3'-5' is read. This strand is read because the RNA polymerase (enzyme used for the synthesis of the mRNA) can only synthesis the mRNA in 5'-3' direction. So, the synthesized mRNA is present in 5'-3' direction.
Hence, the first blank can be filled with 3'–5' and the second blank caan be filled with 5'–3.
5'–3 direction is the correct answer.
Further explanation:
Transcription is the process by which the RNA synthesis that occurs from a DNA. RNA polymerase is the enzyme used in the process of transcription. Transcription depends on the complimentary pairing of bases for example, the Adenine nucleotide pairs with the Uracil nucleotide and thymine nucleotide will pair with adenine nucleotide by double bonds and the Guanine nucleotide will pair with the Cytosine nucleotide via triple bonds. There is a local detachment of the two strands of the double helix and the strand goes about as the template strand. The template must be always present in the direction 3'-5' due to the unique property of RNApolymeraseenzyme. The RNA polymerase enzyme can only synthesize the mRNA in 5'-3' direction. So, the growth of RNA is always in the 5'-3' direction i.e. heading for example the nucleotides are constantly included at a 3' developing tip. As a result of the antiparallel idea of the nucleotide matching, the way that RNA is incorporated 5'- 3' signifies that the template strand must be oriented 3'- 5'.Hence, the first blank can be filled up with 3'– 5' and the subsequent blank can be filled up with 5'– 3’. Thus, the appropriate answer 3'- 5';5'- 3' is right.
