Question

Which of the following is NOT included in a Ty noninfectious particle?

1) Full length RNA
2) RT
3) ds DNA
4) TyB (integrase)
5) TyA (capsid)
6) All of the above are included

Answer 1

A Ty noninfectious particle does not include double-stranded DNA (dsDNA); this is produced after reverse transcription within the host cell.

Step-by-step explanation:

The question deals with the composition of a Ty noninfectious particle, which is an element of yeast retrotransposons. The components of Ty particles include full-length RNA, reverse transcriptase (RT), and proteins such as TyA (capsid) and TyB (integrase). However, Ty noninfectious particles do not include double-stranded DNA (dsDNA) as this is only formed after the reverse transcription of the RNA within the host cell. Therefore, the correct answer to the question, "Which of the following is NOT included in a Ty noninfectious particle?" is ds DNA.
