Question

The DNA of eukaryotes is typically categorized into highly repetitive, moderately repetitive, and unique sequences. Which of the following is true with respect to these categories?

a. highly repetitive DNA consists of several important gene families.
b. most active genes would be found in the unique DNA category.
c. unique sequences represent simple repeated sequences whose functions are unknown.
d. moderately repetitive sequences are very short, typically less than 10 bases in length.
e. highly and moderately repetitive sequences do not represent any active genes.

Answer 1

In eukaryotes, DNA is categorized into highly repetitive, moderately repetitive, and unique sequences. Highly repetitive DNA consists of several important gene families, whereas active genes are mostly found in the unique DNA category. Unique sequences represent non-repeated sequences with unknown functions. Moderately repetitive sequences are typically longer than 10 bases in length and can also contain active genes.

Step-by-step explanation:

In eukaryotes, DNA is categorized into highly repetitive, moderately repetitive, and unique sequences. Highly repetitive DNA consists of several important gene families. Most active genes would be found in the unique DNA category. Unique sequences represent non-repeated sequences with unknown functions. Moderately repetitive sequences are typically longer than 10 bases in length. Both highly and moderately repetitive sequences can represent active genes.
