DNA

__________ is a single-stranded nucleic acid that contains the sugar ribose.

• DNA

• RNA

__________ is a type of RNA that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell.

• rRNA

• mRNA

• tRNA

__________ is a type of RNA that combines with proteins to form ribosomes.

• tRNA

• mRNA

• rRNA

__________ is a type of RNA that carries each amino acid to a ribosome during protein synthesis.

• tRNA

• mRNA

• rRNA

The synthesis of an RNA molecule from a DNA template, or pattern is called ________________.

• translation

• replication

• transcription

During transcription, 

• RNA is converted into DNA
• DNA is split into 4 strands
• DNA is converted into mRNA
• enzymes are not involved

RNA polymerase is 

• an enzyme that uses one strand of DNA as a template to create a strand of RNA
• a ribosome that creates proteins
• an enzyme that uses RNA as a template to create a strand of DNA
• a molecule that creates RNA through translation

The four nitrogenous bases present in an RNA strand are;

• uracil, thymine, guanine, and adenine
• adenine, guanine, cytosine, and thymine
• adenine, guanine, uracil, and thymine
• adenine, cytosine, guanine, and uracil

I am a single strand.

• DNA

• RNA

I am arranged as a double helix or "twisted ladder".
