Understanding Transcription Proteins - Biology

During transcription, transcription factors will bind to promoter sites on the 5' side of the gene to be transcribed. Although the answer "a gene" is technically correct, the more accurate answer is promoter site—the region of DNA that initiates transcription.

A peptide strand is the product of translation, and does not bind transcription factors.

Ribosomes help read the RNA that is eventually transcribed from the DNA, but transcription factors do not interact directly with the ribosomes.

Plant cells are eukaryotic, thus they have nuclei. The process of mRNA synthesis is called transcription. Transcription occurs in the nucleus in eukaryotes. In prokaryotes, it occurs in the cytoplasm. Note that rRNA synthesis and ribosome assembly takes place in the nucleolus.

The genetic code is read in triplets. The addition of a single nucleotide would shift the triplets such that they are no longer read in the correct frame. This is called a frameshift mutation. A truncated protein could be a result of an insertion, but this is not the most likely result. Early transcriptional termination would not be a likely result of an insertion, since this is mediated by long GC repeats or a protein called rho in prokaryotes. Eukaryotic transcriptional termination is not well-understood.

RNA polymerase II is the primary protein responsible for generating mRNA.

RNA polymerases I and III transcribe other RNAs (such as tRNA and rRNA). DNA polymerase is responsible for DNA replication during the S phase of the cell cycle.
