unit 5: DNA and Protein Synthesis

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 size and shape of proteins determines:

• their function

• their bonds

• their nucleotides

• their chromosomes

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

What is this a picture of?

• nucleotide

• DNA strand

• chromosome

• gene

Label the picture in order:

• phosphate ; sugar ; base

• phosphate ; base ; sugar

• base ; sugar ; phosphate

• base ; phosphate ; sugar

DNA is shaped in a:

• double helix

• tightly packed swirl

• twisted ladder

• nucleotide
