Viral reproductive cycle where the viral DNA becomes part of the host cell's DNA
Lytic cycle
Lysogenic cycle
Binary fission
Replication
Viral reproductive cycle where the virus takes over the host cells functions, and forces it to make more viruses
Lytic cycle
Lysogenic cycle
Binary fission
Replication
Which is the proper order for the steps of the lytic cycle?
Attachment, injection, replication, assembly , lysis
Lysis, injection, attachment, assembly, replication
Injection, assembly, replication, attachment, lysis
Replication, assembly, Injection, attachment, lysis
Viruses such as HIV and cold sores are called temperate viruses because they
integrate their DNA with the host's DNA, and can cause illness much later
only cause illness immediately (soon after infection), because they enter the Lytic cycle
replicate more virulently, causing RNA to leak out of the cell
are DNA retroviruses
RNA viruses can cause problems for humans because they
mutate more easily than DNA viruses
are all retroviruses
break down ribosomes in the host cell
All viruses have
a capsid and DNA/RNA
a capsid, DNA/RNA, and an envelope
a capsid, DNA/RNA, an envelope, and enzymes
DNA/RNA and an envelope
Capsids are made of
nucleic acids
proteins
lipids
lipids and proteins
Part of a virus that protects the nucleic acid and recognizes the host cell
capsid
DNA/RNA
membrane
proteins
Viruses are non-living
True
False
Viruses are
smaller than a bacterium
smaller than a eukaryotic cell, but larger than a bacterium
approximately the same size as a bacterium
approximately the same size as a eukaryotic cell
Viruses cannot reproduce on their own, they require a host cell to be able to make more viruses.
True
False
Antibiotics can cure both bacterial and viral infections
True
False
HIV is an example of this type of RNA virus that can make DNA from its RNA genome, and then integrate that DNA with the host cell's DNA
retrovirus
lytic virus
virulent virus
obligate intracellular parasite
A step of the lytic cycle where the host cell explodes, releasing many new viruses
attachment
injection
replication
lysis
A step of the lytic cycle where the host cell produces viral proteins and viral nucleic acid
attachment
injection
replication
lysis
