How does nucleic acid affect your body?
Nucleic acid is an important class of macromolecules found in all cells and 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.
What are RNA diseases?
In eukaryotes, RNA is transcribed from genomic DNA. RNA molecules undergo multiple post-transcriptional processes such as splicing, editing, modification, translation, and degradation. A defect, mis-regulation, or malfunction of these processes often results in diseases in humans, referred to as ‘RNA diseases’.
What are the health problems that can arise from a deficiency of nucleic acids?
These diseases include Lesch-Nyhan syndrome, mitochondrial depletion syndromes, and ataxia telangiectasia. Although treatment options are available to palliate symptoms of these diseases, there is no cure.
What is the nucleic acid in a virus?
Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.
Why do viruses have nucleic acids?
The nucleic acid encodes the genetic information unique for each virus. The infective, extracellular (outside the cell) form of a virus is called the virion. It contains at least one unique protein synthesized by specific genes in the nucleic acid of that virus.
What is the biggest human cell?
ovum
What are the smallest bacteria?
Mycoplasma genitalium, a parasitic bacterium which lives in the primate bladder, waste disposal organs, genital, and respiratory tracts, is thought to be the smallest known organism capable of independent growth and reproduction. With a size of approximately 200 to 300 nm, M.
Which organism has the largest cell?
Summary: Biologists used the world’s largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants. It is a single cell that can grow to a length of six to twelve inches.
What is the smallest multicellular organism?
It is the only species in the phylum placozoa. Trichoplax is comprised of a few thousand cells that differentiate into four types. It has no neural or muscular systems. It basically looks and acts like a large amoeba.
Which animal has only one cell?
Some amoebas are larger than this animal. But an amoeba has just one cell.
Is ostrich egg a cell?
Technically, the yolk of an ostrich egg is one cell though it is rather specially adapted. All the nucleotide material is contained in a small volume at the edge of the yolk. The bulk is a supply of `raw material’ that the cells of the growing embryo use to assemble the cells of the ostrich chick.
What is the smallest unit in life?
cell
Are eggs the largest cell?
The sperm is the smallest cell in human biology, but also one of the most complex. The egg meanwhile is the largest cell and similarly intricate. Looking further out into the natural world, the diversity of these sex cells, or gametes, is truly remarkable. Most species have two gametes, which we term male and female.
What color are ostrich eggs?
They are glossy cream-colored, with thick shells marked by small pits. The eggs are incubated by the females by day and by the males by night. This uses the coloration of the two sexes to escape detection of the nest, as the drab female blends in with the sand, while the black male is nearly undetectable in the night.
How many eggs is an ostrich egg?
Under natural conditions, a female ostrich lays 12–18 eggs.
What does ostrich egg do?
Ostrich eggs were commonly used as food in the villages of the Serengeti district, but such eggs were mostly used for decoration or as a fertility treatment, and rarely for food, in Ngorongoro district. Eggs are also used to protect children from bad spirits and to increase livestock productivity.
