During transcription, the information on a DNA molecule

is "rewritten" into an mRNA molecule.

True

Only DNA molecules contain the

nitrogen base called uracil

False

Only ribosomal RNA plays a role in translation

False

A codon is for a specific amino acid

True

RNA nucleotides contain the five-carbon

sugar ribose

True

In RNA molecules, adenine is complementary to:

Thymine

or

uracil

Uracil

During transcription...

proteins are synthesized

or

mRNA is produced

mRNA is produced

RNA differs from DNA in that RNA

contains the nitrogen base uracil

or

All of the above

All of the above

codon : mRNA ::

DNA : protein

or

anticodon : tRNA

anticodon : tRNA

Refer to illustration

The anticodons for the codons in the mRNA given are:

GAG-UUC-ACG-AAG

or

GAG-TTC-ACG-AAG

GAG-UUC-ACG-AAG

Refer to illustration

What is the portion of the protein molecule

coded for by the piece of mRNA given?

Val-Asp-Pro-His

or

Leu-Lys-Cyc-Phe

Leu-Lys-Cyc-Phe

Each nucleotide triplet in mRNA that specifies a

particular amino acid is called a (n)

codon

or

anticodon

codon

Each of the following is a type of RNA except:

carrier RNA

or

ribosomal RNA

carrier RNA

RNA is chemically similar to DNA except that its sugars

have an additional oxygen atom, and the base thymine 

is replaed by a structurally similar base called

uracil

or 

alanine

uracil

In order for translation to occur, mRNA must migrate to

ribosomes

or

RNA polymerase

ribosomes

The function of rRNA is to

form ribosomes

or

transfer amino acids to ribsomes

form ribosomes

Transfer RNA

carries an amino acid to its correct codon

or

synthesizes amino acids as they are needed

carries an amino acid to its correct codon

Which of the following is NOT found in DNA?

adenine

or

uracil

uracil
