Genetics and DNA Exam

DNA stands for

• Dioxyribo Nucleic Acid

• Dunder Nucleic Acid

• Dopamine Nucleic Acid

• Deciduous Nucleic Acid

What are the parts of a nucleotide?

• phosphate, sugar, base

• A, T, G, C

• Nucleic Acids

• two base pairs connected

Which of the following is correctly matches: ATT GTA CGA

• TAA CAT GCT

• ATT GTA CGA

• TAA GTA TCG

• GCC ACG TAC

The 'backbone' or 'ribbon' of the DNA strand is made of:

• phosphate and sugar

• phosphate only

• phosphate and base

• sugar and base

Hydrogen bonds occur:

• on the ribbon (between the sugar)

• between the bases

• only between A & T

• only between G & C

DNA is shaped in a:

• double helix

• tightly packed swirl

• twisted ladder

• nucleotide

the process of making a copy of DNA

• transcription
• double helix
• DNA replication
• replication fork

Which shows the correct complementary base pairing for DNA?

• C-A, T-G
• A-G, C-T
• C-G, U-A
• T-A, G-C

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

A process in which DNA has the unique ability to make an exact copy of itself.

• Replication
• Translation
• Transcription
