Question 21

What are the four characteristics of a genetic material?

Answer 21

Replication of self. Storage of info. Expression of info. Variation through mutation.

Question 22

Which experiments dealt with transformation?

Answer 22

Griffith. Avery and McCarty

Question 23

What did Griffith experiment do and show?

Answer 23

Taking virulent bacteria and avirulent bacteria and injecting it into a mouse. Virulent bacteria kills mouse, avirulent mouse lives. Heat killed virulent bacteria mouse lives. Heat killed virulent bacteria with avirulent bacteria mouse dies. This shows something transformed the avirulent bacteria into virulent. Showing indication of genetic material.

Question 24

True or False? Just because something is necessary does not means that its sufficient to cause infection

Answer 24

True

Question 25

What did McCarty and Avery experiment do and show?

Answer 25

Trying to show which is the genetic material, protein, RNA, or DNA. This was done by doing the same experiment as Griffith but treating each one with either protease (get rid of proteins), ribonuclease (get rid of RNA), or deoxyribonuclease (get rid of DNA). The correct one will not give virulent bacteria. Results: DNA is our genetic material.

Question 26

What did Hershey and Chase experiment do and show?

Answer 26

Wanted to show if protein or DNA was the genetic material. This was done with bacteriophage confirmation. Made radioactive phage. Sulfur labeled protein and Phosphorous labeled DNA. Radioactive phages were mixed with non radioactive bacteria. Results: S is left outside and P is left inside the bacteria. DNA is the genetic material.

Question 27

What are the three parts of a DNA nucleotide?

Answer 27

Deoxyribose (sugar), phosphate group, and nitrogenous base

Question 28

Which nitrogenous bases are Purines?

Answer 28

Question 29

Which nitrogenous bases are Pyrimidines?

Answer 29

C,T, U (RNA)

Question 30

True or False? Doesn't matter identity of base pair, it will always be the same width

Answer 30

True

Question 31

Through what group are the nucleotides linked through?

Answer 31

Phosphate group

Question 32

What is the function of DNA?

Answer 32

Storage

What is the function of RNA?

Answer 33

Transport, catalysis, regulation

Question 34

What is the structure of DNA?
