DNA Basics Review

A strand of DNA with the sequence A-C-T-T-G serves as a template to form a strand of mRNA with the sequence U-G-A-A-C.  During which process would this happen?

• replication
• transcription
• translation
• meiosis

The diagram shows the base sequence of a strand of DNA.
From left to right, what is the sequence of the complementary strand of DNA in this molecule?

• T G A A C
• A C T  T G
• T G U U C
• U C T T G

The table shows several DNA codons and their corresponding amino acids.
If a sequence of DNA reads AGTGGGTCT, for what sequence of amino acids does it code?

• arginine-glycine-serine
• serine-arginine-arginine
• serine-arginine-glycine
• serine-glycine-serine
