by producing important proteins

Question 6

Gene Therapy

Answer 6

the process of replacing a faulty/defective with a working one, which allows the body to make the protein or enzyme which eliminates the cause of the disease

Answer 9

when thinking of having a baby to know if you might carry a certain disease

Question 10

How is genetic testing done?

Answer 10

with a blood test

Question 11

DNA Fingerprinting

Answer 11

analyzing DNA, and identifying an individual from it

Question 12

We all have ____ DNA with slight _____

Answer 12

similar; differentiations

Question 13

Answer 13

twins

Question 14

DNA Fingerprinting is used in

Answer 14

forensics

Question 15

STR stands for

Answer 15

short tandem repeats

Question 16

How many STRs are there in each genome

Answer 16

13 `

Question 17

STR

Answer 17

part of DNA that is enough to identify a person

Question 18

Establishing relations

Answer 18

solution to the genetic recombination which scrambles the molecular markers used for DNA fingerprinting which makes it hard to find the parents of a child

Question 19

How do you establish relations with fathers?

Answer 19

with the Y-Chromosome

Question 20

How is the Y-Chromosome used in establishing relations with fathers?

Answer 20

because it never undergoes crossing over and is passed from father to son with little changes

Question 21

How do you establish relations with mothers?

Answer 21

mtDNA

Question 22

mtDNA is

Answer 22

mitochondrial DNA — DNA in the mitochondria

Question 23

How is the mtDNA used in establishing relations with mothers?

Answer 23

mtDNA is passed directly from mother to child bc it comes from the cytoplasm of the egg

Question 24

CRISPR

Answer 24

gene editing tool from bacteria that will be an important tool in gene therapy
