Mr. A.H., age 44, had a generalized tonic-clonic seizure unexpectedly at work_ He had no history of seizures, trauma, infection,
NemiM [27]

Answer:

a tumor is a growth of abnormal cells in the brain tissue, in this case they are malignant cancer cells since their growth is very fast, some are primary that start directly in the brain and other metastatic that start in another part of the body, in the case of Mister AH always had primary symptoms.

Tumors in the brain can show various symptoms. These are some of the most common:

Headaches, usually in the morning

Nausea and vomiting

Changes in the ability to speak, hear or see

Balance or walking problems

Problems with thinking or memory

Weakness or longing to sleep

Changes in mood or behavior

Seizures

tumors can destroy brain cells which can cause inflammation and damage to parts of the body depending on where in the brain this is exerted, this also aggravates the symptoms.

Radiation therapy used to treat brain cancers increases the risk of brain tumors up to 20 to 30 years later.

In this case, he was causing this same reaction to Mr. AH, which may also have another type of tumor such as

Meningiomas and schwanomas are two other types of brain tumor. These tumors:

They occur in most cases between the ages of 40 and 70.

They are not usually cancerous, but they can still cause serious complications and death due to their size or location. Some are cancerous and aggressive.

A transcription unit that is 8,000 nucleotides long may use 1,200 nucleotides to make a protein consisting of approximately 400
bearhunter [10]

Answer:

A) many noncoding stretches of nucleotides are present in mRNA.

Explanation:

A transcription unit in eukaryotes includes the region that code for mRNA extending from the 5' cap site to the 3' poly-A site. It also includes the controlling regions. The mRNA formed by transcription also has some non-coding intervening sequences. These are called introns. Introns are removed from the primary transcripts by the process of splicing that occurs after transcription.

Therefore, a transcription unit that is 8,000 nucleotides long may use only 1,200 nucleotides to code for a protein having 400 amino acids since the rest of the nucleotides are part of introns and are removed from mRNA after transcription.
