NonAmoeba Recap [based on] Amoeba Sisters Video: DNA Replication

Explain what is meant by the "lagging" strand and why this occurs.

• The lagging strand is slower than the other strand because it has to buffer before it can start.

• It's lazy compared to the other strand so we call it lagging. The other strand is very productive.

• It replicates at a slower pace because it is being replicated in the opposite direction of the replication fork.

• This is still under research by many scientists; We need more information on this "lagging" strand.

What tells the polymerase where to start?

• Ligase

• Primase

• Helicase

• Lipids

In the game Fortnite, if a player's structure is damaged, which tool acts like a 'Ligase'?

• A tool that breaks the structure apart by removing the connections between the parts

• A tool that marks the starting point for the repair process

• A tool that rebuilds the structure by adding new parts to the original, damaged structure

• A tool that binds or "glues" fragments of the structure together

Why does DNA need to replicate before cells divide?

• So that each cell has a full copy of DNA

• So it has extra genetic material in case a mutation arises

• So they can use the extra chromosomes to fill and "pad" the cell before dividing

• DNA doesn't need to replicate before the cell divides.

Which enzyme builds a new DNA molecule by adding complementary strands of DNA to the original, unzipped DNA molecule?

• Primase

• Helicase

• Ligase

• DNA Polymerase

Which enzyme unzips the double stranded DNA by breaking the hydrogen bonds holding the bases together?

• Ligase

• Helicase

• Primase

• DNA Polymerase

In the game of Fortnite, if a player's character had the function of a Helicase in DNA replication, what would be their role?

• They would be the one who creates a starting point so others know where to begin building

• They would be the one who connects or "glues" different parts of the fort together

• They would be the one who breaks down the fort by breaking the bonds holding the parts together

• They would be the one who builds a new fort by adding complementary parts to the original, broken down fort

In the game of Fortnite, what is the function of a 'Primase' tool if it were to function like it does in DNA replication?

• A tool that marks a starting point so the 'DNA polymerase' tool knows where to begin working

• A tool that unzips the the double stranded DNA by breaking the hydrogen bonds holding the bases together

• A tool that builds a new DNA molecule by adding complementary strands of DNA to the original, unzipped DNA molecule

• A tool that binds or "glues" fragments of DNA together

What full term does the abbreviation, "DNA" represent?

A DNA nucleotide is made of a deoxyribose molecule (sugar), a phosphate group, and a nitrogen base (Adenine, Cyosine, Guanine, or Thymine).

In RNA, the utilized sugar molecule is __________________ and Thymine is exchanged for ______________.

• deoxyribose, adenine

• ribose, adenine

• deoxyribose, uracil

• ribose, uracil
