DNA Test

Question 0

Polymers

Answer 0

Made of many repeating monomers

Question 1

Monomers

Answer 1

Single unit

Question 2

Base Pairing Rule (Char-gaff’s Rule)

Answer 2

Adenine always pairs with Thymine

Cytosine always pairs with Guanine

Question 3

Helicase

Answer 3

Moves down DNA molecule and separates two strands of double helix, result is formation of two DNA template strands

Question 4

DNA Polymerase

Answer 4

Forms covalent bonds b/w newly paired nucleotides

Question 5

Free Floating DNA

Answer 5

In environment of DNA template strands

Available to form complementary strands pairs with nucleotides on template strand

Question 6

Process of DNA Replication

Answer 6

Unwinding of double helix by Helicase and formation of two DNA template strands (Hydrogen bond breaks)
Addition of complementary nucleotides and covalent bonding by DNA polymerase

Question 7

Aug

Answer 7

Met (Start)

Question 8

Central Dogma of Biology

Answer 8

Two step process, transcription & translation, which information in genes flows into protein
DNA —> RNA —> Protein

Question 9

Genetic Code

Answer 9

Set of rules by which information within genetic material such as DNA is translated into protein by living cells
Determines everything about a person
AUG-start codon
64 triplets of nucleotides

Question 10

Translation for Reading

Answer 10

Position corresponds with order of letters

Question 11

Relationship

Answer 11

3 nucleotides = 1 codon

1 amino acid = 1 codon

Question 12

Missense Mutation

Answer 12

Leads to amino acid change

Question 13

Nonsense Mutation

Answer 13

Causes premature STOP codon before protein is complete

Question 14

Frameshift Mutation

Answer 14

(Insertion/deletion/duplication) Changes frame reading, alters protein

Question 15

Silent Mutation

Answer 15

Nucleotide change but no amino acid change
