Answer: D) carcinogens

Explanation:

Mutagen is a chemical or physical agent which is capable enough to change the genetic make up of the organism hence, result in mutation. The mutagen can be in the form of radiation such as X-rays, UV rays, heat or chemical substances. The carcinogens are the chemical substances which are capable of causing mutations which are responsible for cancer.

A mutation occurred in the following DNA sequence AGCCTAGCC and the mutated form is now AGCCTTAGCC. Which of the following corre
Ilia_Sergeevich [38]

Answer:

Explanation:

1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.

2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.

3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.

4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

describe the water cycle here on Earth and explain how it demonstrates the law of conservation of matter.
Nitella [24]

Answer:

Start with evaporation. Place a full cup of water in front of a sunny window. Use a marker to make a line at the beginning water level.

After evaporation we have condensation. When the water vapor reaches the sky it cools to form clouds.

Finally, a precipitation experiment. Again, fill a cup almost full with water.

Explanation:

Matter is conserved because atoms are conserved in physical and chemical processes. As complex as the water cycle is, water molecules are conserved and endlessly recycled in nature. Conservation of mass is a physical law that s never broken.

you're welcome!!

What would most likely happen if an error occurred when RNA was receiving coding information?
MariettaO [177]
If an error occurred when RNA was receiving coding information a protein wouldn't be formed correctly. RNA need's coding information to determine what type of protein it needed to produce. Hope I helped!
