In the context of organic chemistry, what are short tandem repeats?
A
Complex carbohydrates composed of repeating sugar units
B
Single nucleotide polymorphisms that occur at a specific position in the genome
C
Long chains of amino acids forming proteins
D
Sequences of DNA where a short nucleotide sequence is repeated multiple times in a row
Verified step by step guidance1
Understand that short tandem repeats (STRs) are sequences in DNA where a short nucleotide sequence is repeated consecutively.
Recognize that STRs are not related to carbohydrates, single nucleotide polymorphisms, or proteins, but are specific to DNA sequences.
STRs are important in genetic studies and forensic science because they are highly variable among individuals, making them useful for identification purposes.
The repeated sequence in STRs can vary in length, typically consisting of 2 to 6 base pairs, and the number of repeats can differ between individuals.
In summary, STRs are distinct from other biological molecules and are characterized by their repetitive DNA sequence structure.
