Explain how proteins are involved in controlling mitosis.

Biology

SashulF [63]1 year ago
5 0

Explanation:

Almost all eukaryotic proteins are subject to post-translational modifications during mitosis and cell cycle, and in particular, reversible phosphorylation being a key event. The recent use of high-throughput experimental analyses has revealed that more than 70% of all eukaryotic proteins are regulated by phosphorylation; however, the mechanism of dephosphorylation, counteracting phosphorylation, is relatively unknown. Recent discoveries have shown that many of the protein phosphatases are involved in the temporal and spatial control of mitotic events, such as mitotic entry, mitotic spindle assembly, chromosome architecture changes and cohesion, and mitotic exit. This implies that certain phosphatases are tightly regulated for timely dephosphorylation of key mitotic phosphoproteins and are essential for the control of various mitotic processes. This review describes the physiological and pathological roles of mitotic phosphatases, as well as the versatile role of various protein phosphatases in several mitotic events.

Please help! I will give brainliest!! Summarize the steps of transcription. (picture above)
max2010maxim [7]

Answer:

Step 1: Initiation - begins at the region of the DNA called the Promoter

Step 2: Elongation - the enzyme RNA polymerase reads the bases in the unwound unwound DNA strand and adds complimentary RNA nucleotides to create a new RNA strand.

Step 3: Termination - the process ends when the enzyme reaches a region of DNA called the termination or stop sequence which indicates the end of the transcription.

Explanation:

Transcription is the process in which RNA molecules are synthesized from the information stored in the DNA found in the nucleus. The region of the DNA that codes for genes is transcribed, or copied, into messenger RNA, known as mRNA, which then leaves the nucleus and enters into the cytoplasm where the information it carries is used to synthesize proteins.

Transcription occurs in three steps which are summarized below:

Step 1: Initiation - begins at the region of the DNA called the Promoter

Step 2: Elongation - the enzyme RNA polymerase reads the bases in the unwound DNA strand and adds complimentary RNA nucleotides to create a new RNA strand.

Step 3: Termination - the process ends when the enzyme reaches a region of DNA called the termination or stop sequence which indicates the end of the transcription.

MA_775_DIABLO [31]

Answer:

In the case of arson,  investigators must look for the most intensely burned debris to find the origin of the fire. In the case of an explosion, there will also be a crater at the site of the blast. With either type of event, chemical residues can tell how the event happened.

The arson and explosion investigator must take detailed notes during every step of the process. These notes are used to write a full report about the analysis and its conclusions. If the evidence from the analysis is used in a case that goes to trial, the arson and explosion investigator may be required to testify in court about the work.

Arson and explosion investigation is an inspiring field of forensic science that will continue to provide exciting career opportunities well into the future.
