What are the building blocks of DNA called?

• amino acids

• RNA polymerase

• nucleotides

• replication

What are the 3 correct parts of a nucleotide?

• Nitrogen base, hydrogen bond, and sugar

• Phosphate, sugar, nitrogen base

• Sugar, amino acid, phosphate

• Hydrogen bond, sugar, phosphate

If we start with a DNA code that reads CTT AGC, what would the complimentary strand look like?

• GAA TCG

• AGG GTC

• GAA CTG

• GAT TGC

What is the term that is used to describe a DNA molecule that has been wound tightly into a package?

• Nucleic Acid

• Chromosome

• mRNA

Where can we find chromosomes in most living organisms?

• Ribosome

• Nucleus

• Cytoplasm

• Proteins

If we analyzed a strand of DNA and noticed that 19% of the bases were Thymine, what would be true about the Adenine bases?

• Adenine would equal the remaining 81% of the bases

• We cannot determine an answer based on the information provided.

• To know how much adenine there will be, we need a number for cytosine - which is its base pair.

• Adenine would equal the thymine, being about 19%

What is true about a DNA code that has 32% cytosine and 18% adenine?

• It will have 32% thymine.

• It will have 18% guanine.

• It will have 18% thymine,

• Cytosine should match adenine, so this data is incorrect.

Different forms of genes that provide variation in traits are known as what?

• Alleles

• Proteins

• Nucleotides

• Ribosomes

How do alleles create different variations of a trait?

• They are made up of different proteins.

• They are made up of different DNA strands.

• They are made up of different sugars.

• They are made up of different nucleotides.
