CBSEENBI12047484

The translation unit is represented by the following diagram. Select the correct answer based on this

  • Promoter/ Terminater/ Coding strand/ Structural gene

  • Promoter/ Coding strand/ Terminator/ Structural gene

  • Terminater/ Coding strand/ Structural gene/ Promoter

  • Promoter/ Structural gene/ Coding strand/ Terminator

Solution

D.

Promoter/ Structural gene/ Coding strand/ Terminator

Promoter : Located upstream of initiation codon of structural gene. TATA box in prokaryotes and pribnow box in eukaroytes. Highly conserved sequence.

Structural gene - Sequences involved in actual protein synthesis and are the functional unit of inheritance.

Coding strand - 5'- 3' polarity, sequence same as in mRNA except thymine.

Terminator - This region is downstream of structural gene at the 3'-end of coding strand. It defines end of transcription process.
