Q

Pyrimidine?

A

Thymine and cytosine

Has single ring of carbon

16
Q

Chargaff’s Rule?

A 
Purine always pairs with pyrimidine
# of pu = # of py
17
Q

How many hydrogen bonds does the pairing A-T have?

A

2

18
Q

G-C?

A

3 hydrogen bonds

19
Q

Why is DNA twisted?

A

Because of the different number of hydrogen bonds.

20
Q

DNA has anti parallel strands true or false?

A

True

21
Q

Permanent change in the nucleotide sequence is?

A

Mutation

22
Q

Significance of the structure of the DNA?

A
  1. Maintenance of the code during reproduction - constancy of the base pairing guarantees that the code will be retained
  2. Providing variety - order of bases responsible for unique qualities of each organism
23
Q

Why do we need variation?

A

Because the environment changes

24
Q

What are the functions of DNA?

A

Storage of info
Expression of info
Variation by mutation
Replication

25
Q

What is the central dogma of biology?

A

DNA transcription RNA translation PROTEIN

26
Q

All types of genetic material constitutes the genetic makeup?

A

Genotype

27
Q

Expression of the genotype?

A

Phenotype

28
Q

Steps in the process of DNA replication?

A

Unwind and unzip DNA (enzyme will pass through)

provide complimentary strands

29
Q

Why is DNA replication semi conservative?

A

Because the daughter DNA consists of one original strand and one newly synthesized strand
