PROTEIN SYNTHESIS Q3 Flashcards
This is the process that takes place in __________ which the cells generate new proteins. This process involves nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)
Protein Synthesis; ribosomes
Synthesis meaning?
to “make something”
What are the processes of protein synthesis
transcription and translation
It is a copy of a single gene. They have similar structures as to a DNA.
mRNA
It is the process under transcription of creating the equivalent RNA copy of a sequence of DNA.
RNA Synthesis
It is when DNA information must first be copied or transcribed to mRNA. This is done inside the nucleus of eukaryotic cells, since it is where DNA is stored.
Transcription
What are the three steps in transcription.
Initiation
elongation
termination
what happens in the initiation of transcription
where RNA polymerase (an enzyme that generates the formation of RNA) binds the promoter region of DNA
This is an enzyme that catalyzes the formation of RNA, binds to the promoter region of DNA.
RNA polymerase
The _________ is only a short sequence of DNA, located 25 nucleosides upstream of the site where transcription begins.
promoter region
What particular organelle is where protein synthesis is taken place.
ribosome
what happens in the elongation process of transcription.
RNA polymerase proceeds to separate two strands of DNA. reads the bases one by one and it adds nucleotides to the growing mRNA stand.
what happens in the elongation process in transcription
RNA polymerase zips DNA back up, keeping only 10-20 strand bases exposed.
What are the two strands that is used to synthesize mRNA?
Template stand
Anti-sense Strand
what happens in the termination process in transcription?
RNA polymerase and mRNA strand all separate from the DNA template strand.
