DNA is also known as...
deoxyribonucleic acid

How is RNA different from DNA( list three things)?
RNA is smaller and the base thymine is only found in DNA and uracil is found in RNA and the sugars are different(deoxyribose and ribose).
100
How many amino acids are attached to a single DNA?
21
200
a base found only in RNA.
What is uracil?
200
The process of making RNA from DNA is______and it occurs in the _________.
transcription;cytoplasm.
200
Where are genes located in cells?
chromosomes that are made up of DNA.
200
Describe the structure of the RNA( # of strands,sugar, base)
single strand,ribose, AUGC for bases.
200
How many bases are in a codon?In an anticodon?
3;3
300
What is the base-pair rule for DNA?
adenine- thymine cytosine- guanine
300
In _________,the DNA molecules unzip and separate into two strands. Each strand serves as a _______.
replication;template.
300
What are the components of a DNA nucleotide and RNA nucleotide?
DNA- phosphate and deoxyribose sugar backbone and one of 4 bases/RNA- phosphate and ribose sugar backbone and one of 4 bases.
300
Why is RNA necessary to act as a messenger?
It takes the "message" of the DNA to the ribosomes and tells them what proteins are to be made.
300
The entire sequence of the bases that code for all the amino acids in a protein.
What is gene?
400
What type of molecule is represented by the following sequence?Why?
G-U-A-A-U-C-C-G-U
RNA;because it has the uracil base.
400
What is the flow of information in a cell?
DNA->transcription->RNA->translation
400
What does the DNA codes for?
amino acids and proteins.
400
Three types of RNA?
mRNA,tRNA,rRNA

What was the goal of the Human Genome Project?
To sequence all the bases in the human genome.

Fill in the missing step of Transcription.
1.DNA molecule unwinds at a specific gene location.
2.____________________________.
3.The new RNA strand is released and moves into the cytoplasm.
4.The DNA molecules close.
Nucleotides of RNA match up and joint to the template strand of DNA.

Why is DNA called the "Blueprint of life"?
Because every cell in your body has the same "blueprint" and it tells the cell how to build the organisms.

RNA is a place where....
the amino acids are brought together to form a protein.

FINAL JEOPARDY
How do some cells become brain cells and others become skin cells, when the DNA in all the cells are exactly the same?
DNA has the abillity to turn some genes on and off depending on its function- gene regulation.
