What is the structure of DNA?
Single Strand
Single Helix
Double Helix
Triple Helix
What is the sequence of nucleotides of DNA and RNA that determines the amino acid sequence of proteins?
Protein Code
DNA Codes
Ribonucleic Acid
Genetic Code
Why do we call it the 'Universal' Genetic Code?
All life on Earth uses nucleic acids to transmit information.
All life on Earth has identical genes.
All life on Earth has identical DNA codons.
There is no such thing as a 'Universal' genetic code.

RNA
DNA
tRNA
mRNA
What does RNA stand for?
Ribophosphuros Acid
Deoxyribonucleic Acid
Ribonucleic Acid
Ribosomal Acid

Where does DNA replication take place in a Eukaryotic cell?
In the Mitochondria
In the Cytoplasm
In the Ribosomes
In the Nucleus
What are the steps in DNA replication?
1. Free nucleotides pair with matching half
2. Two identical strands formed
3. Enzyme unzips DNA
1. DNA becomes one single strand
2. Enzyme divides it into two perfect halves
1. Enzyme (Helicase) unzips DNA
2. Free nucleotides pair with matching half
3. Two identical strands formed
DNA replication has no steps
