DNA does N O T have proteine or parts of protein in its molecule.
It consists of a 'ribose' part, a 'phophate' part and a 'nucleic acids' part.
No, ethanol is not a holoenzyme. Ethanol is a type of alcohol that can act as a substrate or inhibit the activity of enzymes in biological systems. Enzymes are protein molecules that act as catalysts to facilitate specific chemical reactions in living organisms.
The non-protein part of molecule called cofactor.
Core enzyme (without σ) does not specifically bind promoters, but rather dsDNA very tightly • KD ≈ 5 x 10-12M t1/2 ≈ 60 minutes • Holoenzyme binds non-promoter DNA more loosely • KD ≈ 10-7M t1/2 > 1 sec
Transcription: mRNA is copied from a DNA molecule. Translation: The mRNA molecule then attaches to ribosomes. tRNA carrying amino acids come and attach to Codons on the mRNA. The amino acids bond to form a chain and a protein is formed.
No. Ribosomes are called protein factories because they are the site of protein synthesis.
A holoenzyme consists of both a protein component, known as the apoenzyme, and a non-protein component, known as the cofactor or coenzyme. The cofactor can be a metal ion or a small organic molecule that is necessary for the enzyme's activity. Together, the apoenzyme and cofactor form the functional holoenzyme.
A holoenzyme consists of an apoenzyme (protein component) and a cofactor (non-protein component). The apoenzyme alone is inactive, but once combined with its cofactor, it becomes an active holoenzyme capable of catalyzing a specific biological reaction.
An apoenzyme or an apoprotein is the protein portion of an enzyme that lacks a cofactor. It becomes active when it combines with a cofactor to form a holoenzyme or a holoprotein.
Holoenzyme= Apoenzyme+ coenzyme

The entire sequence of DNA bases responsible for the manufacture of a protein or part of a protein is called a gene. Genes contain the instructions for making proteins through a process called protein synthesis, involving transcription and translation. Each gene has a specific sequence of nucleotide bases that encodes the information for a particular protein.
Enzymes are proteins that catalyze (i.e., increase the rates of) chemical reactions, Coenzymes are small organic molecules that transport chemical group. Inhibitors are activators or molecules that increase or decrease enzyme activity. Apoenzyme is a protein component of an enzyme, to which the coenzyme attaches to form an active enzyme where as holoenzyme is an active, complex enzyme consisting of an apoenzyme and a coenzyme.
A co-substrate is a co-factor that transforms an apoenzyme into a holoenzyme. However, it is not tightly bound to the protein and freely binds and releases (but is not chemically altered). This is different from a tightly bound cofactor such as heme in hemeglobin, these are termed prosthetic groups.
