What is the DNA fingerprinting?
It is a laboratory technique for identify DNA.
What does "STR" stands for?
Short Tandem Repeats
What are alleles?
Alleles are variations of a gene.
What is the other name of DNA fingerprinting?
DNA profiling
What does "PCR" stand for?
Polymerase Chain Reaction
What kind of sources to analysis DNA ?
hair, roots, saliva, and blood
What is flanking sequences?
The bases or nucleotides adjacent to the repeats.
What is band represent?
Band represents pieces of DNA of different sizes
What is homozygous ?
Homozygous has same dominant alleles and recessive alleles.
What does polymerase chain reaction do?
It is create a lot of DNA copies.
Why scientists research about ivory?
Because they want to find out the DNA of elephants for pinpoint where they came from to prevent the attack.
Why are flanking sequences important for amplifying STR fragments?
Primer bind flanking sequence.
What is base pair use for?
it shows the number of DNA fragment in DNA ladder.
What is a keystone species?
If remove keystones, the other species in the ecosystem will be affected.
What do you think wells is?
it is a huge hole that contain water.
Where is locus on?
What is the goal of the "CSI Wildlife" video?
The goal is to match DNA fingerprint for polices to find evidence.
You should guess 5 regions or countries the majority of African elephants inhabit.
- Africa, Kenya, Zambia, South Sudan, Angola.
What is the different between a homozygous to heterozygous?
Homozygous has the both copies of a gene or loci match to each other, but heterozygous has the copies does not match
What are two types of fingerprints?
1. Conventional fingerprints
2. DNA fingerprints
What does genetic marker use for?
It uses to study the relationship between an inherited disease and its genetic cause
What is gel electrophoresis use for?
It is uses for the graph that compare by using DNA ladder and DNA fragment that species.
What is function of primer?
the function of primer is the beginning of the chain reaction.
These primers are then used to amplify the STR fragment from 10 different elephants. What are you think about? Would you expect the fragment to be the same size in all the elephants?
No, because there are a lot of different type of elephants and have different alleles.
Yes or No
Can a DNA profile be obtained from DNA from a fingerprint?
Yes
