Verified step by step guidance1
Understand what transposons are: Transposons, also known as 'jumping genes', are sequences of DNA that can move or transpose themselves to new positions within the genome of a single cell.
Recognize the types of transposons: There are two main types of transposons - DNA transposons and retrotransposons. DNA transposons move directly as DNA, while retrotransposons move via an RNA intermediate.
Identify the role of transposons: Some transposons carry genes that encode proteins necessary for their own transposition, such as transposase in DNA transposons, which facilitates the cutting and pasting of the transposon.
Consider the implications: If a transposon encodes a protein, it means that the transposon itself contains the genetic information necessary to produce a protein, which is a true statement for some transposons.
Conclude based on the information: Given that some transposons do encode proteins, the statement 'Some transposons encode for a protein' is true.
