How does the cell use both dna and rna to direct protein synthesis

Biology

Answer:

DNA and RNA are nucleic acids found in the cells of living organisms. DNA is a two-stranded molecule consisting of a deoxyribose sugar, while RNA is a single-stranded molecule with ribose as its sugar component. There are three primary types of RNA: messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA). Another kind of RNA is small nuclear RNA, or snRNA, which is involved in altering an RNA transcript.

Proteins are one of the vital biomolecules of life. These compounds perform a variety of essential processes to sustain an organism's survival, which include clotting of blood, transporting oxygen, contracting muscles and catalyzing chemical reactions. The building blocks of proteins are called amino acids.

The synthesis of proteins starts with transcribing the instructions in DNA into mRNA. The mRNA is then carried out of the cell's nucleus into the cytoplasm, specifically into structures called ribosomes. The ribosomes, which contain rRNA, are organelles where protein production occurs. The tRNA transports the amino acids to the ribosomes. The code sequence in mRNA is then translated, and specific proteins are synthesized by stringing amino acids together.

A car drives 23 m/s east for 35 seconds. What is the displacement of the car in this time?
trapecia [35]

Answer: 805m east

Explanation:

From the data above v=23m/s, t=35s

Average velocity= Displacement/Time.

Displacement= Average velocity X Time.

Displacement= 23 X 35= 805m

So, the correct answer is 805m east.

When working with radioactive materials you must use radiation detection instruments. Which of the following instruments require
vampirchik [111]

Geiger-Muller tube is instruments requires you test three times the background of the work area.

<u>Explanation</u>:

These detectors are gas filled detectors and hence requires time for responding to the value. This time is taken because during this period it collects the electric charges and features of the electric circuit. It also gets stabilized during this period. This device has thumb rule i.e one must wait or hold for at the least 3 times the time constant before getting the precise and accurate reading. The time constant order is 10 seconds for the ionization chamber but for the Geiger counter it can vary from seconds to greater than 20 seconds

The EKG is hooked up, and Mr. M's trace looks very abnormal. His heart rate is low. The T wave, which indicates repolarization o
azamat

Answer:

This question lacks options, options are: Mr. M's cells are depolarizing too easily. Blocking Nat channels will make it harder for them to depolarize, bringing their sensitivity back to normal O Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Kt channels can stay open and his cells can repolarize properly. Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Na /K+ ATPase can move Kt out of the cell effectively O Blocking Na* channels cannot help- it will only make his cells fire less, and he already has a weak heartbeat. Mr. M's cells are not repolarizing properly. Blocking Nat channels will help them repolarize normally, bringing their resting potential back to normal.

The correct answer is ''Mr. M's cells are depolarizing too easily. Blocking Na+ channels will make it harder for them to depolarize, bringing their sensitivity back to normal.''

Explanation:

Calcium administration is an emerging treatment modality aimed at restoring the transmembrane electrical gradient of cardiac myocytes. It probably achieves this goal by reducing the resting membrane potential of cells. Calcium antagonizes the effect of hyperkalemia on cardiac conduction, that is, it antagonizes the effects of K on the heart. Its onset of action is immediate, in a few minutes. Calcium gluconate antagonizes the excitability of the cardiac membrane, that is, it decreases the excitability of the membrane and it does not affect serum levels, it is generally accepted that calcium should be administered when there are ECG changes associated with hyperkalemia.
