SB2a- DNA Replication & Protein Synthesis

DNA replication begins when the two strands of the original DNA

• are separated by breaking the hydrogen bonds between nitogen bases
• acts as a template to build an mRNA strand
• are separated by breaking the nitrogen bonds between hydrogen bases
• attracts extra nitrogen bases to the nucleus to build a new strand

An mRNA molecule is made through the process of

• Duplication
• Translation
• Transcription
• Crystallography

Each combination of three nitrogen bases on mRNA from a

• anticodon
• enzyme
• nucleic acid
• codon

Which of the following would not be found at the ribosome during protein syntheisis?

• tRNA
• rRNA
• DNA
• mRNA

Which strand is transcribed?

• Strand A
• Strand B

What process is represented by process D?

• Transcription
• Translation
• Replication

What is the function of tRNA?

• Carry the message from the DNA to the ribosome
• Bring amino acids to the ribosome
• Create the structure of the ribosome

After DNA replication, the two DNA molecules that are made are

• opposite
• identical
• unable to replicate again
• inverse

In mRNA, each codon specifies a particular

• nucleotide
• purine
• amino acid
• carbohydrate

A nucleotide does NOT consist of a

• Nitrogen base
• 5 Carbon sugar
• phosphate group
• polymerase
