Vedclass · Answer

(B) Repetitive sequences are stretches of $DNA$ where a few nucleotide sequences are repeated many times.Statement $(a)$ is correct: These sequences generally do not code for any proteins and have no known transcriptional function.Statement $(b)$ is incorrect: Repetitive sequences are primarily found in heterochromatin regions, not euchromatin. Heterochromatin is highly condensed and transcriptionally inactive.Statement $(c)$ is correct: These sequences form the basis of $DNA$ fingerprinting, which helps in identifying individuals based on their unique $DNA$ profiles.Since $(b)$ is the only incorrect statement, option $(b)$ is the correct answer.

Repetitive sequences are stretches of $DNA$ with repeated bases many times in a genome, but
$(a)$ These sequences are of no transcriptional function
$(b)$ These are associated with euchromatin region
$(c)$ These help to identify a person on the basis of their $DNA$ specificity
