Answer:

The correct answer would be 5' capping, 3' polyadenylation , and intron splicing.

In eukaryotes, transcription results in the formation of pre-mRNA which needs to be processed in order to become mRNA (messenger ribonucleotide).

The pre-mRNA processing include:

  • Addition of 5'cap (usually modified guanine nucleotide) at the 5'-end of the RNA. It prevents the RNA degradation and also help in the attachment of ribosome for translation.
  • Addition poly-adenine (poly-A) tail at the 3'-end of the RNA. It increases the stability of the RNA and helps in its export out of the nucleus.
  • Lastly, splicing takes place which removes the introns and joins the exons. Alternative splicing can also take place in order to produce many mRNA from a single gene.

Molodets [167]

Answer:

The correct answer is DNA or RNA. Viral chromosomes exist in a variety of conformations and can be made up of <u>DNA or RNA</u>

Explanation:

The hereditary material of viruses is organized into chromosomes of different types. From the genetic point of view, viruses can be classified into DNA or RNA viruses, double helix or single helix, and circular or linear, that is, viral chromosomes are linear or circular molecules of DNA or RNA. Viruses can be classified according to the type of organism they parasitize in: Bacteriophages or phages, animal viruses and plant-type viruses. Viral chromosomes are also subject to the recombination process, this happens when an individual cell is infected simultaneously by two mutant strains of a virus.

Explain the difference between periods and groups and what each tells you about the atom
Rasek [7]

Answer:

Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

What is an endotherm? how do sweating, fur, and feathers affect the body temperatures of endotherms?
Anton [14]
<span>1. What is an endotherm?
Endotherm is an animal that keeps their temperature constant in a certain range. Keeping temperature is important because most enzyme has an optimal working range. By keeping the temperature at optimal range for the enzyme, the organism can do metabolism more efficient.


2. how do sweating, fur, and feathers affect the body temperatures of endotherms?
The environments temperature should influence the temperature of an organism that lives within it. </span>Endotherms need to control their temperature, so they have some mechanism to increase/decrease the body temperature. or to insulate themselves from the environment.
Sweating help decreasing temperature makes the organism can withstand hot environment. Fur and feather will insulate the body, makes the organism more resistant to cold.<span>
