- Order. Organisms are highly organized, coordinated structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex: inside each cell, atoms make up molecules; these in turn make up cell organelles and other cellular inclusions.
- Sensitivity or Response to Stimuli. Organisms respond to diverse stimuli. For example, plants can bend toward a source of light, climb on fences and walls, or respond to touch (Figure 2).
- Reproduction. Single-celled organisms reproduce by first duplicating their DNA, and then dividing it equally as the cell prepares to divide to form two new cells.
- Growth and Development. All living things increase in size and/or change over their lifespan. For example, a human grows from a baby into an adult and goes through developmental processes such as puberty.

In the central dogma of molecular biology, the genetic information is schematically shown to flow from DNA to DNA (by replication) and from DNA to mRNA (transcription) to protein (translation). In the latter, the genetic code from the mRNA is read as a trinucleotide codon, i.e. a set of three adjacent nucleotides.
DNA replication is the process of producing an exact copy of a polynucleotide strand such as DNA. The flow of genetic information will be from DNA to DNA by complementary base pairing in terms of adenine-thymine (AT) and guanine-cytosine (GC) base pairing. The enzymes involved in the process are DNA polymerases. Conversely, the flow of genetic info...
Protein biosynthesis is the biological process of creating protein molecules. The first step is amino acid synthesis. Amino acids may be produced from carbon sources, e.g. glucose. Nevertheless, not all amino acids need to be synthesized. Some of them can be obtained from dietary sources. After amino acid synthesis, transcription is the next step. ...
Three RNAs are involved in biological translations. They are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA). 1. mRNA is the RNA produced from transcription. It is comprised of a 5′ cap, 5’UTR region, coding region, 3’UTR region, and poly(A) tail. The copy of a DNA segment for gene expression is located in its coding region. It ...
Codon, in biology, refers to the set of three adjacent nucleotides in mRNA. It is also called a triplet. It complementary base pair with the anticodon of aminoacyl-tRNA. Examples: 1. Guanine-Cytosine-Cytosine (GCC) is the codon for the amino acid alanine. 2. Guanine-Uracil-Uracil (GUU) codes for valine. 3. Cytosine-Uracil-Adenine (CUA) codes for le...
Anticodon refers to the sequence of three adjacent nucleotides located on tRNA. It complementary-base -pairswith the codon of mRNA. For example, the anticodon for glycine is CCC (Cytosine-Cytosine-Cytosine) that binds to the codon GGG (Guanine-Guanine-Guanine) of mRNA.
Prior to initiation, a pre-translation step occurs. Called bio-activation, the amino acid binds to the corresponding tRNA by a covalent bond.
The major steps of translation in prokaryotes and eukaryotes are the same (i.e. initiation, elongation, translocation, and termination) and in both cells occurs on the ribosome. Translation in prokaryotes, though, occurs on 70S-type of ribosomes whereas translation in eukaryotes occurs on 80S-type of ribosomes. Because prokaryotes lack membrane-bou...

Apr 27, 2017 · Cell Wall Definition. A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane. All cells have cell membranes, but generally only plants, fungi, algae, most bacteria, and archaea have cells with cell walls. The cell wall provides strength and structural support to the cell, and can control to some extent what ...
Apr 27, 2017 · Cell Definition. Cells are the basic unit of life. In the modern world, they are the smallest known world that performs all of life’s functions. All living organisms are either single cells, or are multicellular organisms composed of many cells working together. Cells are the smallest known unit that can accomplish all of these functions.
