IB Biology HL D1.2.14 Hl Non Coding Sequences in Dna Questions

IB Biology HL D1.2.14 covers DNA sequences that do not code for polypeptides, including introns, regulatory regions, telomeres and genes for functional RNAs such as tRNA and rRNA.

Exam points

Identify non-coding DNA regions, including introns, regulatory sequences, telomeres, and genes for tRNA or rRNA.
Distinguish protein-coding exons from non-coding DNA sequences such as introns and regulatory regions.
State functions of non-coding DNA, such as regulating gene expression, protecting chromosome ends, or producing functional RNA.

[Maximum number: 1]

Some regions of DNA act as telomeres or produce tRNA. State one other function of DNA sequences that do not code for protein.
