DNA Structure
What does DNA stand for?
Deoxyribose Nucleic Acid
Which enzyme breaks the hydrogen bonds unzipping the DNA strands?
Helicase
What does RNA stand for?
Ribose Nucleic Acid
What is the end product of Protein Synthesis?
Proteins
What are the three parts that make up a DNA nucleotide?
Phosphate, Sugar and Nitrogen Base
Which enzyme adds new nucleotides to the new strand of DNA?
DNA Polymerase
How many strands does RNA have?
1
mRNA is transcribing DNA into RNA in the nucleus. Once it is completed it goes to the ribosome.
Where in the cell is DNA located?
The nucleus
What is the complementary bases pairs to the following strand of DNA:
A T C G T C T T A A T
T A G C A G A A T T A
What is the mRNA strand for the following DNA strand?
A T C G A A T C G A T G
U A G C U U A G C U A C
What occurs during the process of translation?
The tRNA matches its anticodons with the mRNA and builds the protein by bonding amino acids.
What type of bonds hold the nitrogen bases together?
Hydrogen Bases
Why is DNA considered to be semi-conservative?
1 strand is original and 1 strand is new
What are the three types of RNA?
mRNA, tRNA and rRNA
Fill in the mRNA, tRNA and Amino Acid
DNA: A T C- G C T- A G A- A T T
mRNA?
tRNA?
Amino Acid?
mRNA: U A G C G A U C U U A A
tRNA: A U C G C U A G A A U U
Amino Acids: Methionine- Arginine-Serine-Stop
Why cant DNA leave the nucleus?
DNA is too big, it is two stranded
Why does DNA replicate?
All new cells need DNA
Which type of RNA is responsible for transcribing the message from DNA and taking it to the ribosome?
mRNA
What could happen if the wrong protein is created due to an error in the mRNA strand?
A Mutation
