What are the 4 nitrogen bases?
Thymine, Guanine, Cytosine, Adenine
Cytosine, Glucose, Adenine, Proteins
Ribosomes, Thymine, Proteins, Nucleus
Thymine Cytosine, nitrogen, Adenine
Which of the following binds to Thymine?

DNA replication occurs before mitosis - when new cells are produced for growth & repair
True
False
IN RNA, which of the following is NOT a nitrogen base?
Adenine
Cytosine
Thymine
Guanine
How many amino acids are in the human body?
20
30
100
26
DNA is a double stranded sugar phosphate with ribose
True
False
What is the first step of DNA Replication?
The free nitrogen bases that are found inside the nucleus react with the available nitrogen bases
Make new DNA in the 5` → 3` direction
DNA Polymerase makes the sugar phosphate bond to make new nucleotide
DNA helicase breaks the the hydrogen bonds between the nitrogen bases
What process does the following occur in?
Occurs so every new cell have a complete copy of the genetic code
DNA Replication
Transcription
Translation
Protein Synthesis
The universal start codon is what?
UGG
CAG
AUG
UCG
Which of the following is a step in translation?
Make new DNA in the 5` → 3` direction
Ribosome attaches to the mRNA at the start codon, AUG.
All the above
RNA polymerase causes available RNA nitrogen bases
(A,U, G, C) to bond with the open DNA.
