Repetitive DNA Part 1

Question 1

2 classes of repetitive DNA

Answer 1

• tandem repeats

- interspersed repeats

Question 2

classes of tandem repeats

Answer 2

• satellites - large tandem arrays
• multiple copy RNA-coding genes
• multiple copy protein-coding genes

Question 3

classes of interspersed repeats

Answer 3

• DNA transposons
• LTR retrotransposons
• non-LTR retrotransposons

Question 4

multiple copy RNA coding genes

Answer 4

• genes whose final product is RNA

Question 5

LTR

Answer 5

• long terminal repeats

Question 6

tandem repeats

Answer 6

• an array of a particular sequence repeated right next to one another in the genome

Question 7

array

Answer 7

• collection of tandem repeats

Question 8

interspersed repeats

Answer 8

• an array of a particular sequence scattered throughout the genome

Question 9

4 categories of satellite

Answer 9

• micro satellite - 2-5 bp
• mini satellite - ~15 bp
• satellite - 5-100 bp
• megasatellite - 4-10 kb

Question 10

VNTR

Answer 10

• variable number tandem repeats

Question 11

total bp added to genome formula

Answer 11

• number of repeats * bp/repeat

- unique DNA*2

Question 12

even if arrays are scattered throughout the genome

Answer 12

• the repeats are considered to be in tandem

Question 13

what DNA sequence must hair pair with primers in PCR reaction to characterize VNTRs

Answer 13

• mini satellites
