Question

Types of DNA sequences include: A. unique sequences, which comprise up to one-half of all protein coding sequences. B. moderately repetitive sequences, which include rRNA genes. C. moderately repetitive sequences, which include interspersed sequences, making up one-fourth of the human genome. D. highly repetitive sequences, also known as satellite DNA due to its distinct density. E. All of the above. Types of DNA sequences include: A. unique sequences, which comprise up to one-half of all protein coding sequences. B. moderately repetitive sequences, which include rRNA genes. C. moderately repetitive sequences, which include interspersed sequences, making up one-fourth of the human genome. D. highly repetitive sequences, also known as satellite DNA due to its distinct density. E. All of the above.

Explanation / Answer

A. unique sequences, which comprise up to one-half of all protein coding sequences. ------> TRUE.

B. moderately repetitive sequences, which include rRNA genes. ------------> TRUE ( moderately repetitive sequences includes redundent genes for histones, rRNA genes and genes coding proteins).

C. moderately repetitive sequences, which include interspersed sequences, making up one-fourth of the human genome. ------------> TRUE, Moderately repetitive squences comprise about 25 to 30% of the genome sequence.

D. highly repetitive sequences, also known as satellite DNA due to its distinct density. --------> TRUE.

Thus, the correct option is E. All of the above.
