Explanation:
In the given question, the options are not provided in the question and neither they are found anywhere therefore based on the previous knowledge this can be answered.
Since both the prokaryotes and eukaryotes are living therefore they perform the metabolism or chemical reactions in the form of process.
Both eukaryotes and prokaryotes perform almost similar process like the cellular respiration, photosynthesis by green colored organisms, the Central dogma related process like the replication, transcription and translation.
The central dogma related processes differ in these process only in terms of the site they are performed and a few modifications which are characteristics of the eukaryotic cells.
In prokaryotes, the transcription and translation are coupled and takes place in the cytosol whereas in eukaryotes transcription in the nucleus and translation in the cytosol.
Also in eukaryotes, modifications like the splicing, alternative splicing, capping and tailing are observed which are not observed in the prokaryotes.
Answer:
The post-transcriptional modifications in the mRNA produced as a result of the transcription in eukaryotes provide many advantages to the mRNA.
The two post-transcriptional modifications are the addition of 7-methylguanosine cap at 5' end of mRNA called capping whereas the addition of the poly(Adenyl) tail at 3' end called tailing.
The advantages of capping are:
1. Protection of nascent mRNA from the degradation.
2. Recognition by transcription factors helps in translation.
The advantages of tailing are:
1. Protection of the mRNA from enzymatic degradation in the cytosol.
2. Transcription termination
3. Export of the mRNA from the nucleus
Answer: Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. This evidence led scientists to look again at Wegener's hypothesis of continental drift.
Explanation:
Answer:
Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood. Common problems include allergies, diseases or infections.
The question is incomplete as it does not have the options which are:
photoreactivation
reactivation repair pathway
nucleotide excision repair pathway
UV repair pathway
p53 repair pathway
Answer:
p53 repair pathway
Explanation:
ATM gene or ataxia telangiectasia-mutated is a gene which codes for the protein kinase involved in the DNA double-stranded break.
The DNA double-stranded break is repaired easily as the protein kinase is recruited to the site of the break where it allows the DNA repair machinery to repair the DNA.
The gene also controls the cell growth therefore this gene is important to study cancer. Since the p53 protein is a suppressor protein which if mutated is repaired by the ATM gene and if the gene becomes mutated then the p53 repair pathway is affected.
Thus, p53 repair pathway is the correct answer.
