Which of the following nucleotides bonds with uracil?

• guanine

• cytosine

• thymine

• adenine

DNA is copied into 2 new strands of DNA during a process called:

• replication

• translation

• transcription

• transformation

In DNA replication, a section of DNA with bases ATTC will line up with bases:

• GAAC

• AUUG

• ATTC

• TAAG

One difference between DNA and RNA is that

• DNA= 1 strand

• DNA contains ribose sugar

• DNA has a double strand

• RNA is more complex

A group of 3 letters representing an amino acid is called:

• nucleotide

• ribosome

• codon

• anticodon

What happens during the process of translation?

• mRNA is made from DNA

• mRNA attaches o tRNA and makes protein

• copies of DNA molecules are made

• transfer RNA is made from mRNA

In protein synthesis, amino acids are brought to the ribosome by:

• DNA

• mRNA

• tRNA

• rRNA
