Function of nucleic acid in viruses

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid DNA encodes the information the cell needs to make proteins. Also Know, which of the following is true about the differences between the types of nucleic acids? The difference between these two nucleic acids is their pentose sugar.

Nitrogenous bases found in nucleic acids are classified as either purines or pyrimidines. Key Takeaways: Nucleic Acids Nucleic acids are macromolecules that store genetic information and enable protein production. These molecules are composed of long strands of nucleotides. Nucleotides are composed of a nitrogenous base, a five-carbon sugar, and a phosphate group. Nucleic Acids They contain carbon, hydrogen, oxygen, nitrogen, and phosphorus; have acidic character ; and are found in all living beings.

They are linear macromolecules formed by the polymerization of units called nucleotides. Which of the following is true about nucleic acids? Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups. Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids.

What are 2 examples of proteins? Examples of Protein Actin. What are nucleic acids made up of? All nucleic acids are made up of the same building blocks monomers.

Chemists call the monomers "nucleotides. Uracil is only found in RNA. What are the two types of nucleic acids? And the nucleic part comes from the fact that they were first isolated because they were found in the nucleus.

And as you know that's where the DNA, one of the types of nucleic acids that we've been talking about, is predominately found. Lawrence C. Brody, Ph. Featured Content. In most, the genomic RNA is termed a plus strand because it acts as messenger RNA for direct synthesis translation of viral protein. A few, however, have negative strands of RNA. In these cases, the virion has an enzyme, called RNA-dependent RNA polymerase transcriptase , which must first catalyze the production of complementary messenger RNA from the virion genomic RNA before viral protein synthesis can occur.

The Influenza Flu Virus - Next to the common cold, influenza or "the flu" is perhaps the most familiar respiratory infection in the world. In the United States alone, approximately 25 to 50 million people contract influenza each year. The symptoms of the flu are similar to those of the common cold, but tend to be more severe. Fever, headache, fatigue, muscle weakness and pain, sore throat, dry cough, and a runny or stuffy nose are common and may develop rapidly.

Gastrointestinal symptoms associated with influenza are sometimes experienced by children, but for most adults, illnesses that manifest in diarrhea, nausea, and vomiting are not caused by the influenza virus though they are often inaccurately referred to as the "stomach flu.

Since that time, a tremendous amount of research focusing upon the causative agent of AIDS has been carried out and much has been learned about the structure of the virus and its typical course of action. HIV is one of a group of atypical viruses called retroviruses that maintain their genetic information in the form of ribonucleic acid RNA. The activity of the enzyme enables the genetic information of HIV to become integrated permanently into the genome chromosomes of a host cell.
