What is the nitrogen base which compliments Adenine?
Thymine
100
What does "transcribe" mean?
To make a written copy of something
100
Where does translation take place and what attaches to the mRNA strand?
In the cytoplasm of the cell, the mRNA attaches to a ribosome
100
What is another word(s) for protein?
polypeptide chain or amino acid chain
100
What is the Human Genome Project?
A project whose goal is to find the sequence of nitrogen base pairs which make up human DNA, also to identify and locate each gene in the human genome
200
What is the DNA "backbone" made of?
Sugar and Phosphate
200
What do you call the new strand that is being created during transcription?
RNA or mRNA
200
The ribosome reads the mRNA in groups of three nitrogen bases. What is this group of three letters called?
a codon
200
What are three things that protein is used for?
to build our muscles, to form our hair, to shape our eyes, to pump our heart, to color our skin, to form structures in our body, etc.
200
How many types of amino acids are there?
20
300
What is holding the nitrogen bases together?
Weak Hydrogen bonds
300
Where does the mRNA go when it is complete?
It leaves the nucleus to find a ribosome
300
What carries the amino acids to the ribosome?
the tRNA
300
What is the codon "AUG" also known as?
a start codon
300
What are genetically identical copies of an organism called?
clones
400
How does such a long strand of DNA fit into the nucleus of a cell?
It is very tightly packed and twisted together to form chromosomes
400
What are the four nitrogen bases in mRNA?
Adenine, Uracil, Guanine, and Cytosine
400
What are the three letters called that compliment the codons on the mRNA strand?
anticodons
400
What are the three types of RNA?
rRNA, mRNA, and tRNA
400
A mistake or change in the DNA sequence can result in what?
a mutation
500
What is so important about DNA?
DNA is the instruction booklet of the cell, it contains all the information needed for the cell to function. DNA tells the cell what to do and how to do it.
500
What is the name of the enzyme which copies the DNA strand to create RNA?
RNA polymerase
500
What amino acid does CAA code for?
Glutamine
500
What are the 3 components(parts) of a nucleotide?
a nitrogen base (A,T,C, or G), a sugar, and a phosphate group
500
If one strand of DNA contains the base sequence AGATCA, what would the complimentary strand be? What would the mRNA strand be? Which 2 amino acids would the mRNA sequence code for?
complimentary strand TCTAGT
mRNA strand UCUAGU
amino acids Serine and Serine
