Warmup-Protein Synthesis-Part 1

What are the differences between DNA and RNA?

• RNA is single stranded; DNA is double stranded

• RNA has the base U; DNA has the base T

• Both

• Neither

mRNA:

• Sends text messages

• Is at the ribosome

• Is the messenger RNA

Name this structure.

• Base

• Nucleotide

• Sugar

• DNA

The process to go from mRNA to a protein is called ____

• transcription
• rRNA
• replication
• translation

What is the function of the poly-A tail in mRNA?

• to add modified guanin to the 3' end of the mRNA
• to indicate the site of translational termination
• to code for the binding of RNA polymerase to the DNA
• to help protect the mRNA from degradation by hydrolytic enzymes 

What is the location in the cell for translation?

• nucleus
• mitochondria
• ribosome
• chloroplast

The genetic code is essentially the same for all organisms. From this, one can logically assume which of the following?

• The same codons in different organisms translate into the different amino acids.
• A gene from an organism can theoretically be expressed by any other organism.
• All organisms have experienced convergent evolution.
• DNA was the first genetic material.

The first step of protein synthesis is.....

• replication

• mitosis

• translation

• transcription

Which Nucleic Acids can be found in the nucleus?

• DNA only

• DNA & RNA

• RNA only

• enzymes only

The molecule that synthesizes the mRNA inside the nucleus

• DNA polymerase

• Nucleotides

• RNA polymerase

• helicase
