Biology

Complete the following questions. Illustrates theprocess of DNA transcription, translation, and proteinsynthesis.

1.    The stages of transcription areinitiation, elongation, and termination. Draw a representation ofeach of these stages . Be sure to include the names of importantenzymes and locations.

2.    Once mRNA is created throughtranscription, it is often processed. Explain how mRNA can beprocessed. Include the names of important enzymes orstructures.

3.    Translation is how mRNA gets used tocreate the peptide sequence. Draw what is going on inside aribosome. Be sure to include the locations of mRNA, tRNA, eachsubunit of the ribosome, and where the amino acid sequence forms.

1Transcription is the process in which the genes DNA sequence is copied or transcribed to make an RNA moleculeRNA polymerase is the main transcription enzymeTranscription begins whwn RNA polymerase binds to a promoter sequence near the beginning of a genedirectly or through helper proteinsRNA polymerase uses one of the DNA strandsthe template strand as a template to make a new complementary RNA moleculeTranscription ends in a process called terminationTermination depends on sequences in the RNAwhich signal that the transcript is finished Transcription is an essential step in using the information from genes in our DNA to make proteinsProteins are key molecules that gives cell structure and keep them running Transcription is the first step of gene expressionBefore transcription can takes placethe double helix must unwind near the gene that is getting transcribedthe region of opened up DNA is called transcription bubble Transcription uses one of the two exposed DNA strands as a templatethis starnd is called template strandThe RNA product is complementary to the template strand and is almost identical to the other DNA strandcalled the non template strandHoweverthere one important differencein the newly made RNAall of the T nucleotides are replaced with U nucleotides The site on the DNA from which the first RNA molecule is transcribed is called the 1 site or the initiation siteNucleotides that come before the initiation are given negative numbers and said to be    See Answer
