Where in the cell does the fist step (transcription) of protein synthesis take occur?
|
|
in the cell membrane
|
|
|
on the rough ER
|
|
|
in the nucleus
|
|
|
at the ribososmes
|
Explanation:
Detailed explanation-1: -Transcription happens in the nucleus of the cell. During transcription, a strand of mRNA is made that is complementary to a strand of DNA called a gene.
Detailed explanation-2: -In eukaryotes, the first step (transcription) occurs in the nucleus. When the transcript (mRNA) is formed, it proceeds to the cytoplasm where ribosomes are located. Here, the mRNA is translated into an amino acid chain.
Detailed explanation-3: -The nucleus is the site where DNA is replicated, and DNA is transcribed to make messenger RNA (mRNA) signals to start the process of translation or protein synthesis which occurs in ribosomes in the cell cytoplasm (all the cell body except the nucleus).
