6.2 - DNA Replication

DNA replication is initiated by ____ that unzip the hydrogen bonds

• proteins

• enzymes

• carbohydrates

• nucleic acids

DNA replication needs a​ (a)   from the ​ (b)   to make a ​ (c)  

• template
• parent molecule
• daughter strand
• non template
• orignial molecule
• son strand

When it comes to DNA replication, SEMICONSERVATIVE means the new DNA is made with:

(select all that apply)

• 1 parent strand

• 2 parent strands

• 2 daughter strands

• 1 daughter strand

These 3 components are required for DNA Replication to start

• Replication Fork

• DNA Polymerase

• DNA Helicase

• Origin of replication

The number of​ (a)   bonds between ​ (b)   and T is ​ (c)   .

The number between G and ​ (d)   is ​ (e)   .

• A
• 3
• hydrogen
• covalent
• C
• 2
• 1
• 4
• U
• T

Organize these options into the right categories

Groups:

(a) DNA Helicase

,

(b) Origin of Replication

,

(c) Replication fork

• enzyme that unzips DNA into single template strands

• The unzipped exposed DNA strand that creates a template for replication

• Substrate of DNA nucleotides for DNA Helicase to bind to to begin DNA Replication

What is NOT one of the 4 components are needed for REPLICATING DNA?

• DNA Polymerase 3

• Primase

• Primers

• Amylase

• Single Strand Binding Proteins

Enzyme that binds to a single strand to add new nucleotides
