Dimitri Ivanowsky
- B.
Martinus Beijerinck
- C.
Wendell M Stanley
- D.
Adolf Mayer
- E.

D. Adolf Mayer
E. Karl JohnsonExplanation
Adolf Mayer and Karl Johnson were the first scientists to conduct research on viruses. Adolf Mayer, a German scientist, first observed and described the tobacco mosaic disease caused by a virus in 1886. Karl Johnson, an American scientist, independently discovered the virus causing yellow fever in 1901. Their contributions were significant in laying the foundation for the field of virology and understanding the nature of viral infections.Rate this question:

Virus dianggap bukan makhluk hidup, dikarenakan...
- A.
Virus merupakan non seluler
- B.
Asam nukleat virus tidak dapat mensinteis protein
- C.
Virus tidak dapat bereproduksi sendiri
- D.
Virus tidak bergerak
- E.
Benar semua
Correct Answer
E. Benar semuaExplanation
The correct answer is "Benar semua" which means "All are correct" in English. The question asks for an explanation for this answer. The given options state that viruses are non-cellular, cannot synthesize proteins, cannot reproduce on their own, and do not move. All of these statements are true and provide valid reasons for considering viruses as non-living entities. Therefore, the answer "Benar semua" is correct.Rate this question:

Bagian-bagian berikut yang ditemukan pada semua virus...
- A.
DNA, RNA dan protein
- B.
Sampul, asam nukleat, dan protein
- C.
Protein dan asam nukleat
- D.
Lipid, protein, karbohidrat dan asam nukleat
- E.
Serat ekor, duri dan sampul
Correct Answer
C. Protein dan asam nukleatExplanation
All viruses contain protein and nucleic acid (either DNA or RNA) as their basic components. Protein is essential for the structure and function of the virus, while nucleic acid carries the genetic information of the virus. Other components mentioned in the options, such as lipid, carbohydrate, and tail fiber, may be present in some viruses but are not found in all viruses. Therefore, the correct answer is protein and nucleic acid.Rate this question:

- E.
Materi genetik, kapsid, sampul
Correct Answer
E. Materi genetik, kapsid, sampulExplanation
The correct answer is "Materi genetik, kapsid, sampul." This is because the genetic material of the HIV virus is located inside the virus particle, followed by a protein coat called the capsid, and finally, an outer envelope or "sampul" that surrounds the virus.Rate this question:

Correct Answer
C. 2, 4,5Explanation
The correct answer is 2, 4, 5. This is because classification of viruses based on host cells is a common method used in virology. In this classification, viruses are categorized based on the type of host cell they infect. Option 2 includes the numbers 2, 4, and 5, which suggests that the correct answer is 2, 4, 5.Rate this question:

Tahap fage merakit partikel virus
- B.
Tahapan fage melepaskan enzim pada dinding sel
- C.
Tahapan fage menempel pada dinding sel
- D.
Tahapan mengambil alih mesin metabolisme sel
- E.
Tahapan partikel virus meninggalkan sel
Correct Answer
C. Tahapan fage menempel pada dinding selExplanation
The correct answer is "Tahapan fage menempel pada dinding sel." This is because the word "menempel" means "to attach" or "to adhere," indicating that the fage stage involves the virus particles attaching themselves to the cell wall. This is a crucial step in the viral life cycle as it allows the virus to gain entry into the host cell and initiate infection.Rate this question:

Pelepasan, adsorbsi, penetrasi, sintesis, pematangan
- E.
Adsorbsi, penetrasi, sintesis, pematangan, pelepasan
Correct Answer
E. Adsorbsi, penetrasi, sintesis, pematangan, pelepasanExplanation
The correct answer is "Adsorbsi, penetrasi, sintesis, pematangan, pelepasan". This is the correct order of events in the lytic replication cycle of a bacteriophage. Adsorbsi refers to the attachment of the bacteriophage to the host cell. Penetrasi is the entry of the viral genetic material into the host cell. Sintesis involves the replication of the viral genetic material and the production of viral proteins. Pematangan is the assembly of new viral particles. Pelepasan is the release of the newly formed viral particles from the host cell, allowing them to infect other cells.Rate this question:

Pada replikasi bakteriofage, tujuan memasukkan DNA ke dalam sel inang adalah...
- A.
Mengeluarkan protoplasma sel inang untuk tempat reproduksi
- B.
Mengaktifkan enzim nukleus sel inang
- C.
Melumpuhkan sel inang agar tidak bisa bereproduksi
- D.
Mengendalikan sintesis protein dan membentuk bagian-bagian tubuhnya
- E.
Memacu produksi enzim untuk melisiskan sel inangnya
Correct Answer
D. Mengendalikan sintesis protein dan membentuk bagian-bagian tubuhnyaExplanation
The correct answer is "Mengendalikan sintesis protein dan membentuk bagian-bagian tubuhnya". In the replication process of bacteriophages, the goal is to control the synthesis of proteins and form the different parts of their bodies. This allows the bacteriophages to reproduce and continue their life cycle.Rate this question:

- A.
RNA-->RNA
- B.
DNA -->RNA
- C.
RNA -->DNA
- D.
Protein-->DNA
- E.
RNA--> protein
Correct Answer
C. RNA -->DNAExplanation
HIV is a retrovirus that uses the enzyme reverse transcriptase to convert its RNA genome into DNA. This DNA can then be integrated into the host cell's genome, allowing the virus to replicate and produce more viral RNA. Therefore, the correct answer is RNA --> DNA.Rate this question:

Correct Answer
B. Rabies-RhabdovirusExplanation
The correct answer is Rabies-Rhabdovirus. Rabies is a viral disease that affects the central nervous system and is caused by the Rhabdovirus. The virus is transmitted through the saliva of infected animals, usually through bites. It affects the brain and spinal cord, leading to symptoms such as fever, headache, and difficulty swallowing. If left untreated, rabies can be fatal.Rate this question:

Apel
Correct Answer
B. TembakauExplanation
CPVD stands for Cekaman Penyakit Virus Daun, which translates to Leaf Virus Disease Stress in English. CPVD is a common disease that affects tobacco plants. This disease is caused by viral infections and can lead to stunted growth, yellowing of leaves, and reduced yield. It is important for tobacco farmers to be aware of CPVD and take necessary measures to prevent and control the spread of this disease in order to ensure healthy crop production.Rate this question:

Gerakan 3M (mengubur, Menguras, Menutup)
- B.
Vaksinasi
- C.
Pemberian antibioti
- D.
Evakuasi
- E.
Pengobatan simptomatik
Correct Answer
B. VaksinasiExplanation
Vaksinasi adalah tindakan yang biasa dilakukan untuk mencegah serangan virus. Dengan memberikan vaksin kepada individu, sistem kekebalan tubuh akan mengembangkan kekebalan terhadap virus tertentu, sehingga jika terpapar virus tersebut, individu tersebut akan memiliki perlindungan yang lebih baik dan kemungkinan terkena penyakit akan berkurang. Vaksinasi telah terbukti efektif dalam mencegah penyebaran virus dan mengurangi angka kesakitan dan kematian akibat penyakit yang disebabkan oleh virus tersebut.Rate this question:

Penyakit flu babi disebabkan oleh virus tipe:
- A.
H1N1
- B.
H3N2
- C.
H5N1
- D.
H9N2
- E.
H5N2
Correct Answer
A. H1N1Explanation
The correct answer is H1N1 because the question asks for the type of virus that causes swine flu. H1N1 is a subtype of the influenza A virus that primarily affects pigs but can also infect humans. It caused a global pandemic in 2009, commonly known as the swine flu pandemic. H3N2, H5N1, H9N2, and H5N2 are also subtypes of influenza A virus, but they are not specifically associated with swine flu.Rate this question:
