Replication and protein synthesis

Question 11

Explain replication for DNA?
(3 points)

Answer 11

• 2 strands of double helix separate and
• act as templates for synthesis of
• 2 new complementary strands

Question 12

Explain protein synthesis for DNA?
(3 points)

Answer 12

• Base sequence represents info carried by DNA
• Determines sequence of amino acids (primary)
• in proteins

Question 13

How is DNA suited to its functions?
(im writing 2 things)

Answer 13

1. Very stable molecule, info content unchanged from generation to generation
2. Large molecule = large n° of genetic info

Question 14

Quick structure of DNA?

Answer 14

Forms a double helix
(that’s all i got T-T)

Cytosine and uracil

Question 19

Quick structure of RNA?

Answer 19

Single stranded

Question 20

What are the 3 different types of RNA?

Answer 20

• Messenger RNA (mRNA)
• Transfer “ (tRNA)
• Ribosomal “ (rRNA)

Question 21

What sugar is RNA?

Answer 21

Ribose

Question 22

Where does DNA replication take place?

Answer 22

Interphase
(aww hell nah this is linton type shit)

Question 23

Step 1 of DNA replication?

Answer 23

DNA molecule unwinds

Question 24

Step 2 of DNA replication?
(3 points)

Answer 24

• DNA unzips (separation of polynucleotide strands)
• From the helicase enzyme (he breaks hydrogen bonds)
• Leases exposed

Question 25

Step 3 of DNA replication?
(2 points technically)

Answer 25

• Free nucleotides activated + attracted to exposed bases
• And thus align with complementary bases
  (A-T & C-G)

Question 26

Step 4 of DNA replication?
(2 points)

Answer 26

• DNA polymerase joins nucleotides together
• To form new strands (simple dimple D:)

Question 27

Step 5 of DNA replication?

Answer 27

2 new identical DNA molecules are formed

Question 28

Step 6 of DNA replication?

Answer 28

DNA winds up into a double helix

Question 29

How is ATP called the universal energy currency?
(2 things)

Answer 29

• Used by all organisms/species to provide energy
• for most biochemical reactions

Question 30

There’s additional info on ATP type shit sooooo yeeeee, it’s at the end of the booklet

Answer 30

okay…. hopefully i can revise most materials D:
