Read the following statements and choose the correct option: 1. The coding sequences or expressed sequences are defined as exons. 2. Monocistronic genes are present in bacteria or prokaryotes and polycistronic genes are present in eukaryotes 3. The ribosome consists of structural RNAs and about 80 different proteins. 4. Inheritance of a character is not affected by promoter and regulatory sequences of a structural ge

Options

  1. Aall are correct
  2. BOnly 1 and 5 are incorrect
  3. C1,2,3 are correct
  4. DOnly 2 and 4 are incorrect

Correct answer

D. Only 2 and 4 are incorrect

Step-by-step solution

The coding sequences or expressed sequences are defined as exons. polycistronic genes are present in bacteria or prokaryotes and monocistronic genes are present in eukaryotes. Exons are said to be those sequence that appear in mature or processed RNA. Inheritance of a character is also affected by promoter and regulatory sequences of a structural gene.
