DNA Replication Formative Assessment

The process of DNA replication is called semi conservative because it results in

• none of these

• Two DNA molecules.  One original molecule and one with two new strands

• two exact copies with new strands

• two DNA molecules, each with 1 original strand and one new.

Why does DNA replicate?

• To create a duplicate copy in case the original gets damaged

• New cells will have a copy of the DNA

• To create a new copy to replace the damaged original

Adenine bonds with _____

• Cytosine

• Thymine

• Guanine

• Uracil

Why is DNA important?

• it is very small and very complicated

• it's in everything

• it serves as the blueprint for traits of all living things

• because we eat it every day for energy

Cytosine bonds with ____

• Adenine

• Thymine

• Guanine

• Uracil

What does DNA stand for?

• Deoxyribonucleic acid

• Denitrogenous acid

• Deribonucleic acid

• Diribonucleic acid

The picture below shows the steps of DNA replication beginning with step one and ending with step three.

​Because you are reusing the old, or parent, DNA strand DNA replication is said to be

• Semi- Conservative

• Semi-discontinuous

• Continuous

• Fully-Conserveative

The picture below shows an enzyme unwinding and unzipping DNA.

​

​What is the name of this enzyme?

• DNA Helicase

• DNA Ligase

• DNA polyermase

• RNA Polymerase

The directionality of DNA is said to be ___________, because it is side by side by goes in opposite directions.

• Anti-directional

• Parallel

• Anti-parallel

• Anti-uniform
