If a substitution changes the amino acid to a “stop,” it's called a NONSENSE mutation. frameshift, missense, silent or nonsense (hint: deletion or insertion will always be frameshift). Sickel cell anemia is the result of a type of mutation in the gene that codes for part of the hemoglobin molecule.
It depends on which virus you are referring to specifically. Viruses come in many shapes and types; their variations are tremendous.
For HIV and Influenza, viruses acquire their envelops after maturation, during the budding off or detachment stage from the host cell.
Hope this helps! :)
Function of mRNA
The mRNA is formed inside the nucleus in a process called transcription. This mRNA contain codon responsible for the formation of specific type of protein. In translation this mRNA is converted into protein.
Function of tRNA
tRNA is found in cytoplasm and possess amino acids. During translation they attach to the base pair of mRNA with the help of anti-codons.
Formation rRNA:
rRNA is the principle component of ribosome. Ribosome is that organelle which help in attachment of mRNA and contribute in translation.
