A

Nucleus, mitochondria/chloroplasts, cytoplasm

20
Q

Nucleic acids physical description?

A

viscous, snotty

21
Q

What are the four characteristics of a genetic material?

A

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

22
Q

Which experiments dealt with transformation?

A

Griffith. Avery and McCarty

23
Q

What did Griffith experiment do and show?

A

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.

24
Q

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

A

True

25
Q

What did McCarty and Avery experiment do and show?

A

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.

26
Q

What did Hershey and Chase experiment do and show?

A

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.

27
Q

What are the three parts of a DNA nucleotide?

A

Deoxyribose (sugar), phosphate group, and nitrogenous base

28
Q

Which nitrogenous bases are Purines?

A

A,G

29
Q

Which nitrogenous bases are Pyrimidines?

A

C,T, U (RNA)

30
Q

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

A

True

31
Q

Through what group are the nucleotides linked through?

A

Phosphate group

32
Q

What is the function of DNA?

A

Storage

33
Q

What is the function of RNA?

A

Transport, catalysis, regulation

34
Q

What is the structure of DNA?

A

2 strands

35
Q

What is the structure of RNA?

A

1 strand

36
Q

What is the sugar of DNA?

A

Deoxyribose

37
Q

What is the sugar of RNA?

A

Ribose

38
Q

What are the Pyrimidines of DNA?

A

C,T

39
Q

What are the Pyrimidines of RNA?

A

C,U

40
Q

What are the Purines of DNA?

A

A,G

41
Q

What are the Purines of RNA?

A

A,G

42
Q

What is the anatomy of a gene (DNA)?

A

Regulatory, promoter, coding region, regulatory

43
Q

What is the anatomy of a gene (mRNA)?

A

5’UTR, Exons and introns, 3’UTR, polyA tail
