<span>It is true that AIDS is classified as a chronic disease, as the AIDS- related illnesses are not the primary threat, since the patients have access to treatment, but the complications resulting in a chronic disease.</span>
Answer:
Explanation:
There are 3 different types of DNA dependent RNA polymerase. RNAP II is the main enzyme synthesizing mRNAs.
1. Signals for initiation of transcription
Promoters: there are certain specific areas on the DNA that act as starting signals for initiation process.
The DNA polymerase attaches to the promoter site on the template DNA strand.
TATA Box: upstream of the transcription start site is 5'-TATAAA-3' it is referred to as the TATA Box. It acts as a signal for the start region.
2. Initiation of Transcription. The DNA helix unwind, and the RNAP binds to the promoter site on the 5' end DNA with the help of sigma factor. RNAP reaches the appropriate site of the gene and add the first nucleotide of the mRNA.
3. Elongation of Transcription: the RNAP moves along the DNA template, new nucleotides are incorporated in the nascent mRNA, one by one, according to the base pairing rule.
4. Termination of transcription: specific signals are recognized by the termination protein (Rho factor). When it attaches to the DNA, rnap can't move further. So the enzyme dissociate from DNA and consequently newly formed RNA is released.
Amoxicillin is a broad-spectrum antibiotic widely used for certain
bacterial infections in the ear, nose, throat, genitourinary tract, skin, lower
respiratory tract, and its also used to treat gonnorhea. Amoxicillin is a
fairly strong drug, and it can elicit an allergy to patients even to those who
had used the drug before and did not experienced any untoward problems. If the patient
had symptoms such as difficulty in breathing, itching, and untoward swelling or
lump in the throat when receiving treatment with penicillins like amoxicillin,
sulbactam, ampicillin, methicillin, or penicillin G, the nurse should
discontinue giving amoxicillin and report to the doctor right away.
Single celled organisms exchange gases directly across their Cell membrane.
