2
What is mRNA used for?
3
The copying of the instructions in the DNA
4
What does mRNA stand for?
5
messenger RNA
6
Where is mRNA before the process of protein
synthesis
7
In the cytoplasm
8
Where does the mRNA go after the copying of the
DNA
9
Ribosome
10
What is the process of copying the DNA in the
nucleus called
11
Transcription
12
What does DNA do
13
Gives instructions to the cell
14
What was the name of the project that discovered
the number and sequence of the chromosomes
15
Human Genome project
16
Who discovered DNA and what did he use
17
Dr. Mendel pea plants
18
What does DNA Stand for
19
Deoxyribonucleic acid
20
What does tRNA do
21
Brings amino acids to the ribosome
22
What does tRNA stand for
23
transfer RNA
24
What role does tRNA play in protein synthesis
25
Transports the amino acids to the ribosome
26
What is the process of reading the tRNA called
27
Translation
28
How many types of amino acids can one piece of
tRNA bond to
29
One amino acid
30
Who was tRNA hypothesized by
31
Francis Crick
32
How many homologous chromosomes are there?
male-female
33
22 male23female
34
What is the definition of Genetics
35
The study of heredity
36
How many genes are there in the human body
37
31,000
38
Why can the DNA not leave the nucleus
39
It is too large
40
What two organelles have their own sets of DNA
and reproduce independently from the cell what
are the names of the DNA

41
Mitochondria mitochondrialRibosome ribosomal
42
What is the name of the process for making protein
43
Protein synthesis
44
What makes up a protein
45
Amino acid
46
Your body cannot make 6 amino acids where can you
get them
47
From the food you consume
48
What type of organism must be able to make all of
the amino acids
49
Plants must be able to make all the amino acids.
Humans, on the other hand, do not have all the
enzymes required for the biosynthesis of all of
the amino acids.

50
What amino acids can our bodies not make
51
arginine (required for the young, but not for
adults), histidine, isoleucine, leucine, lysine,
methionine, phenylalanine, threonine, tryptophan,
and valine
