Final answer:
Amylase, a digestive enzyme, is most likely encoded in the euchromatic region of the DNA, as this region is associated with active gene transcription due to its less condensed DNA structure.
Step-by-step explanation:
The DNA sequence encoding the digestive enzyme amylase is most likely to be found in the euchromatic region. The euchromatin is where the DNA is less tightly packed compared to heterochromatin, making it more accessible for transcription and, therefore, more likely to be actively expressing genes, including those coding for enzymes involved in digestion like amylase.
Regions such as the telomeric, centromeric, and heterochromatic are typically not associated with active gene expression. The telomeric region protects the end of chromosomes and is not usually where genes are located. The centromeric region is responsible for the proper segregation of chromosomes during cell division. Conversely, the euchromatic region is where active transcription takes place, as it contains regions of DNA that is less condensed.
The final answer: the euchromatic region is more likely to contain the DNA sequence encoding for the enzyme amylase due to its association with active gene expression.
