Which can be accomplished by DNA barcoding?
A)determining the sequence of DNA
B)identifying species
C)bringing extinct species back to life
D)tagging genes to make things glow in routine lab experiments
A?
then... B?
thank you
Yes, DNA barcoding can be used for determining the sequence of DNA, so the correct answer is A) determining the sequence of DNA.
To get this answer, we can break down the options and explain how each one relates to DNA barcoding:
A) determining the sequence of DNA: DNA barcoding involves identifying specific regions in the DNA, such as the barcode region, and determining their sequence. This sequence can then be used for species identification.
B) identifying species: This is also correct! DNA barcoding is primarily used for species identification, allowing researchers to differentiate between similar species based on their DNA sequences.
C) bringing extinct species back to life: DNA barcoding is not directly involved in bringing extinct species back to life. However, it can be used to extract and analyze DNA from ancient remains, which can provide insights into the evolutionary history of extinct species.
D) tagging genes to make things glow in routine lab experiments: This is not directly related to DNA barcoding. "Tagging genes" generally refers to genetic engineering techniques like inserting fluorescent proteins into genes, which is different from the concept of DNA barcoding.
Therefore, by eliminating options and understanding the purpose and process of DNA barcoding, we can deduce that the correct answer is A) determining the sequence of DNA.
