Choose the correct statement below about DNA and RNA.
DNA is single-stranded and RNA is double-stranded
DNA contains Uracil and RNA contains Thymine
DNA is made of ribose sugar and RNA is made of deoxyribose sugar
DNA stays in the nucleus and RNA can leave the nucleus
What does one phosphate, one sugar, and one nitrogen base make up?
protein

How does this model represent replication?
each new molecule of DNA is made of two old strands
each new molecule of DNA is made of ONLY new strands
each new molecule of DNA is made of one old strand and one new strand
this model does NOT represent replication
The diagram shows the process by which DNA copies itself. What is the name of this process and how do we describe the model?
replication, conservative
transcription, conservative
translation, semi-conservative
replication, semi-conservative
The codon (3 bases that contain the genetic code) is contained in...
tRNA
protein
mRNA
rRNA
What process is pictured and where does it happen?
translation, nucleus
transcription, nucleus
translation, ribosome
transcription, ribosome
What molecule leaves the nucleus with the genetic message and why?
mRNA, so the genetic code can be taken to the ribosome
DNA, so the genetic code can be taken to the ribosome
mRNA, so the proteins can be made in the nucleus
tRNA, so the proteins can be made in the cytoplasm
