Answer:
Prokaryotes do not have introns, eukaryotes have introns
Explanation:
Prokaryotes do not have introns, eukaryotes do. Introns are regions of DNA that are transcribed but not part of the final protein. They interrupt exons, which are the coding parts of the gene. These are only present in eukaryotes.
Introns need to be removed before the mRNA can be translated into the protein sequence. This occurs by a process called splicing. The splicing machinery binds the junction between introns and exons and excises the intron. The exons are then fused together to create the mRNA.
Other processing steps occur to the eukaryotic pre mRNA to prevent it from being degraded in the cell. This includes adding a cap to the 5' end of the protein, and adding a poly A tail to the 3' end. One these steps are complete, the eukaryotic mRNA is complete.
The prokaryotic mRNA undergoes transcription and translation simultaneously because it doesn't require these processing steps.
I believe the answer is that the turns are formed from complementary base pairing and cause separation of the RNA transcript and RNA polymerase.
A hairpin loop is an unpaired loop of messenger RNA that is created when an mRNA strand folds and forms base pairs with another section of the same strand. Intrinsic termination of transcription in E.coli involves the formation of an RNA hairpin in the nascent RNA. The hairpin plays a central role in the release of the transcript and polymerase at intrinsic termination sites on the DNA template.
YES THAT FIRST SENTENCE IS VERY TRUE.YES, GENE DOPING IS USED BY MANY ATHLETES AROUND THE WORLD.IT CAUSES SEVERAL EFFECTS LIKE:
a) increased extraordinary hematocrit
b) increased thrombotic activity
c) autoimmune anemia,ETC.
ANY TWO GENETIC MODIFICATIONS THAT WOULD IMPROVE THE PERFORMANCE OF AN ATHLETE ARE:
a.gene therapy should be given to produce more hormones in the body.
b. gene therapy is given to athletes because they have been used to study and model cancer (the oncomouse), obesity, heart disease, diabetes, arthritis, substance abuse, anxiety, aging and Parkinson disease to check for the athletes.
