What is the central idea? Fat-Free Chocolate Milk Box
There I was, staring at that fat-free chocolate milk box, so common, so simple, yet something completely new for me, completely different from the bagged yogurts my grandmother packed in my lunchbox along with little snack-sized cakes wrapped in colorful packages. After two days of having arrived in New York City, The fact of being in a completely different place was just starting to hit me, surrounded by a different culture and a different language. I wondered what that little milk box would’ve thought if it found itself surrounded by the fresh bagged whole milk and yogurts I previously had in my school lunches. The smelly, dry, brownish rice on my tray didn't look tasty at all and on top of that, being there made me nervous so I did not feel like eating. Staring at my tray in order to avoid eye contact with the other kids was starting to get boring and weird so opening the milk seemed like my best choice. I wanted to open it, but how? Am I supposed to get a straw and poke it?... Am I supposed to rip the whole thing?... What if I spill it? I don’t want to spill it… Should I ask for help? No.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

this is math not biology xd
