ANSWER KEY
GENETIC Material
Fill in the following table.
DNA
RNA
What does DNA stand for?
What does RNA stand for?
Deoxyribonucleic acid
Ribonucleic acid
What is the name of the sugar that is found in DNA?
What is the name of the sugar that is found in RNA?
Deoxyribose
Ribose
Where is DNA found in a eukaryotic cell?
Where is RNA found in a eukaryotic cell?
Nucleus, mitochondria, chloroplast
Cytoplasm, on the rough ER, assembled in nucleus, (some
students might include mitochondria/chloroplast)
What is the function of DNA?
What is the function mRNA?
Contains instructions for how to make cellular proteins
Direct, single stranded copy of nuclear DNA, contains the
genetic code to be translated
What is the function tRNA?
Transfer amino acids to the growing polypeptide chain
What is the function rRNA?
Component of the ribosomal complex, needed for protein
synthesis
What are the four bases found in DNA?
What are the four bases found in RNA?
Thymine, adenine, guanine, cytosine
Uracil, adenine, guanine, cytosine
In the table below, draw a picture of double stranded DNA and single stranded RNA. Label the sugar, phosphate group
and bases. Color the phosphate groups red, leave the sugars white, and color the base blue.
DNA
RNA
Replication & Transcription
1. What is the purpose of DNA replication? It is necessary to make a copy of DNA for a new cell that will be produced
during cell division. This cell will be genetically identical to its parent cell.
2. During what stage of the cell cycle is DNA replicated? S phase (after G1, before G2)
3. Below is a strand of DNA. Make a Complimentary copy of the strand.
A A G A C C T T G G C A A C T
T T C T G G A A C C G T T G A
4. What is the purpose of transcription? Transcription is the process of making a specific copy of DNA but writing it as
RNA. DNA cannot leave the nucleus, but RNA can. This RNA will then be translated in order to make a protein.
5. Below is a strand of DNA. Transcribe the strand.
