Question

Sequence motifs are the sequences of nucleotides that indicate what types of function or absence of function may be encoded in a particular region of the genome. Which statement is true regarding sequence motifs?

Sequence motifs are found in DNA and in corresponding RNA produced by transcription.
	Sequence motifs are telltale sequences of nucleotides that indicate possible function.
	An open reading frame (ORF) is a type of sequence motif.
	Sequence motifs help identify sequences that encode protein-coding genes.
	All of these choices are correct.

Answer 1

• All of these choices are correct.
  • Sequence motifs are found in DNA and in corresponding RNA produced by transcription.
  • Sequence motifs are telltale sequences of nucleotides that indicate possible function.
  • An opening frame (ORF) is a type of sequence motif.
  • Sequence motifs help identify sequences that encode protein coding genes.

​​​​​​​ In genome annotation,the sequence motif which identifies the location as potentially or probable protein coding.And the sequence motif can be found in DNA itself or in the RNA sequence that are deduced from the DNA sequence.
