DNA Review

DNA stands for

• Dioxyribo Nucleic Acid

• Dunder Nucleic Acid

• Dopamine Nucleic Acid

• Deciduous Nucleic Acid

Which is in order from largest to smallest structure?

• chromosome, DNA strand, gene, nucleotide

• chromosome, gene, DNA strand, nucleotide

• gene, DNA strand, chromosome, nucleotide

• DNA strand, chromosome, gene, nucleotide

What are the parts of a nucleotide?

• phosphate, sugar, base

• A, T, G, C

• Nucleic Acids

• two base pairs connected

One strand of DNA has how many nucleotides

• millions

• about 20

• billions

• thousands

Which of the following is correctly matches: ATT GTA CGA

• TAA CAT GCT

• ATT GTA CGA

• TAA GTA TCG

• GCC ACG TAC

What do genes do?

• make proteins

• store energy

• create covalent bonds

• create hydrogen bonds

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

Covalent bonds occur:

• on the ribbon (between the sugar)

• between the bases

• only between A & T

• only between G & C

Hydrogen bonds occur:

• on the ribbon (between the sugar)

• between the bases

• only between A & T

• only between G & C
