Genetics-Test 2 HW
1) What is a mutation? _______________________________
2) In what type of cell does a germ mutation occur? _________________________________
3) Mutations that occur in regular body cells are called ________________________ mutations.
4) Which type of mutation above can be passed to your offspring? __________________ Why would this be so bad? _________________________________________
5) What is meant by Trisomy-17? __________________________________________________
6) If a person had only one chromosome in pair #7, it would be called _________________________
7) Three chromosomes in every pair is called ___________________ Four in every pair is called _________________________ A general name for more than two chromosomes in each pair is _________________________
8) If one base on DNA is changed, it will change one _____________ which will change one ___________________ in the protein. This is called a ______________________ mutation.
9) If one base in DNA is missing, it will change all the _____________ and all the ____________________ from that point on. This is called a ______________________ mutation.
10) Anything that can cause a mutation is called a _______________________ Give an example _______________________
11) Cells that are _____________________ are more likely to get mutations. Give an example.___________________
12) A family tree is also called a _____________________.
13) Certain ___________________ groups are more likely to have certain recessive bad genes.
14) A picture of your chromosomes lined up by pairs is called a ______________________
15) Amniocentesis and CVS are methods of getting cells from the __________________
16) The danger in being a carrier is that you might marry __________________________. This would mean that you would have a _________% chance of having a kid with the disease.
17) Two people carrying the same recessive bad gene is more likely
if a) they are _________________
or b) they are from the same ______________ group.
18) A genetic disease that can be treated with a special diet is called _____________
19) A genetic disease that affects the shape of red blood cells is _________________________. Carriers of this disease cannot get what other disease? ____________________________
20) A genetic disease where the lungs fill with mucus is ______________________________
21) A genetic disease cause by a dominant gene that doesn't kill you until you are older is ___________________________. This means that you will probably already have _______________ and maybe passed the gene on.
22) Down's Syndrome is also called ___________________________
23) All the genes that a certain type of organism might have is known as its __________________
24) We study identical twins that have been _______________________________ in order to find out which has a greater effect on the- their _________________ or the way they were raised. This is called the ________________ / __________________ discussion.
25) Enzymes that break DNA into certain size pieces are called ____________________ enzymes
26) A process that can make copies of small amount of DNA is called _____________
27) Putting DNA from one cell into another is called ______________________ DNA. If the DNA comes from a different organism, you create a ______________________ organisms
28) Bacteria have been given some human DNA so they will make things like _____________________
29) ____________therapy is when a normal gene is put into cells to replace a bad gene. This has been tried with what disease? ____________________________
30) To get a DNA "fingerprint", the sample DNA is treated with ______________________ enzymes to break it into pieces. The size and number of these pieces is _______________________ for each person.
This can be used to identify the person the DNA came from. This
process is called ____________
(4 letters)
