What is Paramyxovirus?
Paramyxovirus is a type of virus that can cause severe respiratory illness, including pneumonia, in humans. It is highly contagious and can be spread through coughing and sneezing. Paramyxovirus is most commonly spread through contact with respiratory secretions, such as saliva, mucus, or blood. It can also be spread through contact with contaminated surfaces, such as doorknobs, door handles, or countertops. Paramyxovirus can also be spread through contact with infected animals, such as horses, camels, and pigs. Paramyxovirus is most commonly found in the developing world, where access to clean water and sanitation is limited.
Paramyxovirus Virus Genome and Paramyxovirus Causes
The paramyxovirus genome is a single stranded, negative sense RNA molecule. The genome is about 15,000 nucleotides in length and encodes seven proteins. The proteins are:
Nucleocapsid protein (NP)
Matrix protein (M)
Phosphoprotein (P)
Viral polymerase (L)
Hemagglutinin (H)
Neuraminidase (N)
The paramyxovirus causes a wide variety of diseases in humans and animals. The most common diseases are:
Mumps
Measles
Varicella (chickenpox)
SARS (severe acute respiratory syndrome)
The paramyxovirus is also responsible for pandemics such as the 1918 Spanish Flu and the 2009 H1N1 pandemic.
Subfamilies
of the family Hominidae
The family Hominidae includes humans and their closest living relatives, the great apes. The Hominidae are divided into two subfamilies: the Homininae, which includes humans, and the Paninae, which includes the great apes.
Structure
of a typical neuron
A neuron has a cell body, dendrites, and an axon. The cell body contains the nucleus and cytoplasm. The dendrites are branched, and they receive signals from other neurons. The axon is a single, long fiber that carries signals away from the neuron.
Genome
sequencing is the process of determining the order of the nucleotides in the chromosomal DNA of an organism. This process is also called DNA sequencing. The genome sequencing of an organism is the first step in understanding all the genes that the organism has, and what those genes do.
The first genome to be sequenced was that of the bacterium Haemophilus influenzae in 1995. The human genome was sequenced in 2000.
Proteins
are important biomolecules that play a variety of critical roles in the body. They are composed of smaller molecules called amino acids, and the sequence of amino acids in a protein determines its specific function. There are 20 different amino acids that can be incorporated into a protein, and each one has a unique three-letter abbreviation.
Most proteins are constructed from just a small number of these amino acids, and the sequence of these amino acids is determined by the sequence of codons in the gene that encodes the protein. A codon is a three-letter sequence of DNA that codes for a particular amino acid. The genetic code is the sequence of codons in a gene and the sequence of amino acids in a protein.
The genetic code is universal, which means that it is the same for all species. The code is also redundant, which means that there are multiple codons that code for the same amino acid. This redundancy is important because it allows the gene to mutate without affecting the protein.
