2
The building blocks of proteins
3
Amino Acids
4
List 3 protein used by organisms
5
Cell structures, tissues, keratin, collagen,
myosin
6
Protein used for communication
7
Hormones
8
Proteins that catalyze chemical reactions
9
enzymes
10
What does the enzyme lysozyme do?
11
Helps destroy harmful bacteria by cutting a
polysaccharide found in bacterial cell walls
12
RNA synthesis
13
Transcription
14
Where transcription occurs in eukaryotes.
15
Nucleus
16
Three ways that RNA is different that DNA?
17
Uracil, ribose, single stranded, shorter
18
Which types of RNA are synthesized during
transcription?
19
mRNA, tRNA, rRNA
20
Describe the 3 types of RNA
21
mRNA- copies DNArRNA-makes up the
ribosomestRNA-transports the amino acids to the
ribosomes.
22
Where does RNA processing occur?
23
nucleus
24
Why is the RNA after it leaves the nucleus
shorter than after it was transcribed?
25
Processing edits
26
Parts that are edited out of the mRNA?
27
introns
28
Why is processing necessary?
29
To remove nonfunctional parts of the RNA
30
Explain RNA editing and splicing.
31
Snurps form the slicosome and create a lariat to
excise the introns and maintain the exons.
32
Where does translation occur
33
ribosome
34
What is made in translation?
35
Proteins
36
The amino acid code is called __
37
codon
38
Amino acids are always coded from the __
39
mRNA
40
Explain translation
41
mRNA attaches to a 2 part ribosome, tRNA brings
the amino acids to the A site where the codon and
anticodon match the amno acid is transferred to
the polypeptide chain at the P site, the tRNA
exits at the E site.
42
Virus that infects bacteria
43
Bacteriophage
44
Most viruses consist of (2 things)
45
Protein coat and DNA or RNA
46
What is a virus that consists of RNA called?
47
retrovirus
48
Type of viral infection that produce new viruses
49
Lytic infection
50
Explain how lytic and lysogenic infections are
different.
51
Lytic produces new viruses while lysogenic
infections incorporates its DNA into the host
cells DNA and the cell copies can become lytic.
