The p53 protein is a transcription factor that regulates a cell's progression through the cell cycle after DNA is damaged by ult

raviolet ( UV ) radiation. The p53 pathway is shown in Figure 1.
Please answer this question! I will give brainliest!
Please note: p53 regulating image is for the entire problem, whereas part C image is only for part C.

(a) A skin cell completes one round of the cell cycle. Describe the products.
(b) Based on Figure 1, explain how p53 regulates the cell cycle in the presence of damaged DNA .
(c) Draw an X on the template in the space provided for your response to indicate the phase during which the replication of damaged DNA would occur.
(d) Based on Figure 1, explain how a mutation to p53 may lead to an increased risk of cancer.

At what stage and in what eon did the earth develop seasons?
inysia [2303]
C. Era del Precámbrico Tardío. El término eón se refiere a dos o más eras geológicas que componen un eón. Se divide principalmente en cuatro eones: Hadeano, Arcaico, Proterozoico y Fanerozoico. Este último incluye las eras Paleozoica, Mesozoica y Cenozoica. El Cámbrico forma parte de la era Paleozoica, la cual fue un período crucial en la escala de tiempo geológico por el repentino desarrollo de una gran diversidad de filos animales. Durante este tiempo, también apareció la primera planta terrestre, lo que fue un avance prometedor para el crecimiento de vegetación en condiciones estacionales adecuadas.

In E. coli, the primary component of the mismatch repair system is the protein MutS. How does MutS recognize mismatched base pai
-BARSIC- [2551]

Answer:

The most accurate answer to the inquiry, based on findings regarding this specific mechanism in E. Coli, is: D) It detects hemimethylated base pairs and extends the methylation to the unmethylated base.

Explanation:

Research into this complex subject, particularly in E. Coli and other gram-negative prokaryotes, indicates that whether or not methylation is present will trigger MutS, a protein present in both prokaryotes and eukaryotes that plays a crucial role in launching and executing the entire DNA mismatch repair operation. When daughter DNA strands are synthesized from the parent strands, these initial strands often contain various mismatches and deletions that require rectification, identifiable because the daughter strands are hemimethylated. This situation prompts MutS in E. Coli to attach to the damaged DNA strand, and accompanied by other complex members like MutH and MutL, it starts the repair process.

The exact methodology by which MutS repairs DNA in eukaryotes and different prokaryotic organisms remains not entirely elucidated.

In which order do the necessary enzymes act to repair a thymine dimer by nucleotide excision repair?a) nuclease, dna polymerase,
garik1379 [2080]
To fix a thymine dimer via nucleotide excision repair, the sequence of enzyme activity is Endonuclease, DNA polymerase I, and DNA ligase. Two primary methods exist for repairing thymine dimers; one is photoreactivation, where an enzyme activated by blue light repairs the dimer, thus restoring the proper base pairing. The alternative method is excision repair, involving the uvr system that removes the dimer, with the gap filled by DNA polymerase I's proofreading capability.
