An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence. An anticodon is found at one end of a transfer RNA (tRNA) molecule.
Explanation:
Answer:
The correct order is
E. Adsorption
B. Penetration
D. Synthesis
A. Assembly
C. Lysis
Explanation:
Virus can have two reproduction cycle that is lytic and lysogenic. In the lytic cycle first step is virus adsorption or attachment on the host cell surface. The second step is penetration in which the virus penetrated the host cell and injects its genetic material in the host cell.
The third step is synthesis, in this stage, the viral genome gets incorporated and produces viral proteins required for capsid formation. The fourth step is assembly in which viral protein assembled around viral nucleic and form new viruses.
The final step is lysis where the new viruses lyse the host cell to come out of the host cell and infect other cells.
This statement is true. Early land animals indeed had gills as well as lungs. It is generally known that amphibians breathe through their skin, like how the lungs needed the skin for its respiratory. Fish have gills for breathing while mammals do have their nasal cavity and lungs for their gas exchange.
