What is prokaryote and eukaryote? give there characteristic .

igor_vitrenko [27]

Answer & Explanation:

Prokaryote: a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.

Characteristic of prokaryote: lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found in a central part of the cell called the nucleoid. The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.

Eukaryote: an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.

Characteristic of eukaryote: larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes

Describe the chemical components of DNA.

Slav-nsk [51]

DNA is composed of nucleotides, which are composed of three parts:

1. A five carbon carbohydrate (pentose)

Pentose is classified as a monosaccharide (simple carbohydrate), and its molecular formula is represented by $(CH_{2} O)n$ . They are water soluble molecules with sweet taste. Monosaccharides may have from three carbon atoms (trioses) to six (hexoses). In DNA is present pentose (5 carbon atoms)

2. A nitrogenous base

Nitrogenous bases are ring-shaped compounds that contain nitrogen in their molecular structure. They are classified into two groups: purines and pyrimidines

The purine bases are adenine (A) and guanine (G). They are larger and contain more than one ring in their structure,.

The pyrimidines, cytosine (C), uracil (U) and thymine (T), are smaller and composed of a single ring.

3. One or more phosphate groups

A phosphate consists of a trivalent anion that contains one phosphorus atom and four oxygen atoms. Its molecular formula is expressed by $(PO_{4} ^{-3})$ .

How can organism's be so unique if the nucleotides making up DNA are all the same between organism's?

Masja [62]

Every organism is unique, even though the nucleotides making up DNA are all the same, because the structure is different in every organism. In other words, it's just the order in which nucleotides are placed that differs each organism from one another.
