1.24 -1.26

Question 1

What does 1.24 DNA sequencing enables

Answer 1

mapping of genomes

Question 2

What does mapping a species geonome

plus steps thanks

Answer 2

it means determining what genes it
contains, and the location of each gene on the DNA.

• The first step of genome mapping is to sequence the DNA (determine
  the order of bases along every chromosome)
• The human genome has been sequenced, but mapping has not been
  completed.

Question 3

What are the results of electrophoresis used to construct

Answer 3

DNA
profiles

They may be displayed in an electropherogram or in a table of data.

Question 4

How to get the info for electropherograms

look im actually not too sure if this question relates to the info so

Answer 4

• Special primers that are tagged with fluorescent markers are used in the
  PCR process to amplify STR regions
• When the amplified DNA is placed into a capillary electrophoresis tube,
  the smaller STR fragments will move faster
• The fluorescent marker enables each STR to be detected as it passes a laser beam at the end of the capillary tube.
• The result is displayed as an electropherogram

Question 5

what does DNA profiling identify

Answer 5

the unique genetic makeup of
individuals

Question 5

how are dna molecules different in individuals

Answer 5

DNA molecules contain repeating sequences that are highly variable between different species, and between individuals

These repeating sequences are called variable number tandem repeats (VNTRs)
