Protein Synthesis

RNA is able to leave the nucleus because

How are DNA and RNA different? (CHECK ALL THAT APPLY)

• Only DNA can leave the nucleus

• RNA contains Thymine; DNA contains Uracil

• DNA is double stranded, RNA is a single stranded

• DNA contains Thymine, RNA contains Uracil

What mRNA strand would be created using the DNA strand TAC GTA TAT?

• TAC GTA TAT

• UAC GUA UAU

• GCU ACG GCG

• AUG CAU AUA

Which process is happening in this picture?

• Transcription

• Translation

• Replication

In RNA, Uracil pairs with ______. 

• cytosine
• adenine
• guanine
• thymine

In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of

• cytosine
• guanine
• thymine
• uracil

Mutations that change the amino acid specified by the codon, affecting the amino acid sequence, are called:

• nonsense mutations

• missense mutations

• silent mutations

• all of the above

3 bases in a row on the mRNA strand, that call for a particular amino acid to be added to the polypeptide chain:

• chromosome

• gene

• codon

• anticodon

Changes to the number or structure of chromosomes are called chromosomal mutations. Which of the following is NOT a type of chromosomal mutation?

• deletion

• duplication

• inversion

• translation

A nucleotide base is inserted or deleted shifting the entire DNA sequence. Entire protein will be changed.

• Substitution Mutation

• Silent Mutation

• Frameshift Mutation

• Translocation
