TRna is used in translation or transcription ?
liraira [26]

Answer:

Translation.

Explanation:

The mRNA formed in the transcription process is transported out of the nucleus, then goes into the cytoplasm, and then to the ribosome. The ribosome is called the cell's protein synthesis factory.

In the ribosome, it directs protein synthesis. Messenger RNA is not directly involved in protein synthesis. Transfer RNA (tRNA) is required for this. The process by which mRNA leads to protein synthesis with the assistance of tRNA is called translation.

So we can say that the transfer RNA (tRNA) is used in the translation process.

How does mitosis provide for genetic consistency in an organism and why is this important?
castortr0y [4]
 <span>Mitosis is Asexual reproduction. It promotes genetic consistency because all offspring are exactly identical to the parent, unlike meiosis where homologous chromosomes are randomly dispersed between four daughter cells. organisms that only reproduce asexually are at a disadvantage because all organisms in their population are identical so if there were to be a major environmental change, they would have less of a chance of survival compared to a population of sexually reproducing organisms that are all genetically different.</span>
