Final answer:
The statement is true. Transposons, or 'jumping genes', can indeed transport their sequences between different organisms through horizontal gene transfer, contributing to genetic diversity.
Step-by-step explanation:
True or False: DNA-type elements can transport their own sequences into those of different organisms. The answer to this is true. DNA elements known as transposons, or 'jumping genes', have the ability to move around within genomes and can also be transferred between different organisms, a process known as horizontal gene transfer. This has been observed in various species and is a factor contributing to genetic diversity.
Transposons contain inverted repeat sequences and a gene encoding the enzyme transposase, which facilitates their movement from one DNA sequence to another through transposition. These DNA transposons can leave their original location and integrate at another locus ('cut-and-paste' mechanism), or they can replicate themselves and insert copies elsewhere in the genome ('replicative' mechanism). Therefore, the presence of similar transposons in diverse species can be explained by horizontal gene transfer between species.
