DNA Synthesis

DNA replication results in

• 2 completely new DNA molecules

• 2 DNA molecules that each contain a strand of the original

• 1 new DNA molecule and 1 old

• 1 new molecule of DNA

DNA strand has the following bases AAGCCA what are the bases on the complementary strand

• GGCTTA

• TTGGGA

• CCAGGT

• TTCGGT

The new DNA strand formed after DNA replication is an exact copy of its parent strand

• True

• False

Key players in DNA Replication are...

• enzymes

• sugars

• fats

• amino acids

What is the function (job) of an enzyme?

• speed up reactions

• insulators

• main source of energy

• code for traits

Semi = half

Conservative = to keep

What does "DNA is semi-conservative" mean?

• DNA keeps half of the original strand and creates a new strand

• DNA keeps both original strands

• DNA does not keep any old strands at all and makes completely new strands

What makes up the SIDES of a DNA ladder?

• nitrogen bases

• sugars & phosphates

• genes & chromosomes

• RNA

What makes up the rungs (steps) of a DNA ladder?

• sugars & phosphates

• nitrogen bases

• sugars

• genes & chromosomes

What is the significance of the sequence (order) of the Nitrogen Bases in DNA?

• The order of the Nitrogen Bases determines the number of chromosomes present in an organism.
• The order of the Nitrogen Bases determines the traits that an organism will possess (have).
• The order of the Nitrogen Bases determines the gender of an organism.
• The order of the Nitrogen Bases determines whether an organism is abiotic biotic.
