<span>Galvanometer guess.....</span>
When speaking about pre-molars, we would only contain 8 pre-molars, and this is due because we only contain 32 teeth.
We have : (8 pre-molars)
We have : (12 molars)
We have : (8 incisors)
And for the last part, we would contain : (4 canines).
Answer:
B
Explanation:
RNAi is a cellular mechanism for post-transcriptional gene silencing. After transcription of a gene into mRNA, small interfering RNA (siRNA) and microRNA (miRNA) can target the mRNA to form dsRNA. This mRNA then becomes a target of ribonucleases such as the Dicer that break it apart. These mRNA, therefore, do not reach the cytoplasm for translation by ribosomes. This mechanism is hence harnessed and manipulated by scientists to study genes by silencing them.
