What is the difference between rRNA, tRNA, mRNA and codon,anticodon
Eddi Din [679]
MRNA, is used to transcript DNA codes from DNA molecules and then later exits the nucleus via nuclear pore, then moves to the ribosome. Then, tRNA is activated to bring specific amino acid to the ribosome for translation. Ribosome, which is the site of synthesis of proteins, is composed of rRNA and ribosomal proteins.
A codon is a three-base sequence (three nitrogen bases in a row) on mRNA. An anticodon is a three-base sequence on tRNA. It matches the codon.

What have the scientific studies identified as the major cause of acid rain in the united states?.
Vadim26 [7]

Burning of fossil fuels that release sulphur and nitrogen compounds into the air is identified as the major cause of acid rain in the united states.

<h3>What are the causes of acid rain?</h3>
  • Acid Rain is created when sulphate and nitrogen oxides from the atmosphere react with rainwater and fall as a result.
  • Sulphur and nitrogen particles that mix with the wet elements of rain are the main causes in the production of acid rain.
  • Due to air pollutants, notably the excessive levels of sulphur and nitrogen released by machinery and industrial operations, acid rain is made up of water droplets that are extremely acidic.
  • The emissions that are released from industries are man-made causes.
  • The natural causes, such as lightning strikes in the atmosphere that release nitrogen oxides and volcanic eruptions that release sulphur oxide.

The complete question is :
