DNA sequencing

Question 1

what are VNTRs ( variable number tandem repeats )

Answer 1

• many repetitive, non coding sequences of nucleotide bases

Question 2

How do VNTRs correlate with how closely an organism is related to another

Answer 2

• the more related two organisms are , the more similar their VNTRs will be

Question 3

what is DNA sequencing

Answer 3

• the determining of the sequence of DNA nucleotide bases in an organism (genome)

Question 4

why is DNA sequencing important?

Answer 4

• can be used to identify the proteom which can help identify potential antigens for use in a vaccine

Question 5

why is the genome not always reliable for finding out the proteome

Answer 5

• in more complex organisms the DNA base sequence may contain introns or regulatory genes that don’t code for proteins
