the start of transcribing signal is a nucleotide sequence called a "promoter", which is located in the beginning of a gene. its a specific place where RNA attaches and starts synthesis and the prmotoer dictates wish of the DNA strands is to be transcribed
Transcription starts in the nucleus, when a mRNA strand forms a template of the DNA. the DNA unwinds, and free bases (A,C,T,G) attach to the mRNA strand. when this is finished the DNA 'zips' back together, and the mRNA strand moves through the nucleus and into the cytoplasm to the ribosomes. once the mRNA leaves the nucleus, transcription has ended and translation starts
ribosomes use tRNA that carry the amino acids to complete the protein synthesis process.
basically, in the RNA strand in the ribosome there are triplets of bases (C,G,A,U) and the tRNA have corresponding triplets that code for a specific amino acid. if the RNA sequence is GCA, then the matching tRNA would be CGU. let's say CGU codes for Arginine (Arg), the CGU tRNA would have an arginine amino acid on the end.
this tRNA triplet with attached amino acid is drawn to the ribosome, and if the triplet fits the RNA strand then the amino acid will form a polypeptide bond with the last amino acid in the chain.
when the ribosome reaches a stop codon, the amino acid chain is finished and folds to form a protein!
and there you have DNA transcription, translation and protein synthesis :)
RNA polymerase creates a transcription bubble, and this separates the two strands of the DNA helix. This breaks the hydrogen bonds between complementary DNA nucleotides.
In protein synthesis, transcription begins inside the nucleus where the DNA template is being used to make mRNA.
in chromosomes ahahahhaahaha!!/
i think it starts in the promoter
Right after the start codon.
The process of transcription.
The process that involves the transcribing of genetic information from DNA to RNA is called Transcription.

transcription
Transcription.During transcription the base sequence (genetic code) of part (a gene) of one strand of DNA is copied onto a strand of RNA as the RNA is synthesized.
transcription
Transcription results in messenger Rnas that are passed to the process called translation [Rna to protein].

It's called transcription. But transcription is part of a larger process called protein synthesis.
