What motor molecule is associated with the microtubules in cilia and flagella?

dimer


What is receptor dimerization?

Receptor dimerization is the joining of the receptor proteins. It this step does not take place, then the responder protein will not autophosphorylate. Signal transduction will not occur if the receptor proteins do not join together.


A molecule with two amino acid units is a?

Single amino acids are monomers, and monomers of amino acids join by peptide bonds to form polypeptide polymers.A polymer consisting of two monomers is a dimer.


Abbreviation for the disease in which one of the enzymes needed to repair sunlight damsaged DNA is missing?

Ultra violet radiation from sunlight causes Pyrimidines in DNA to bind together in a way they aren't supposed to. This binding most often occurs between two thymines creating a thymine dimer. The dimer must be cut out of the DNA strand and replaced in a process called Nucleotide Excision Repair. In the disorder Xeroderma pigmentosum (abbreviated XP) one or more of the excision repair enzymes is missing leading to extreme sensitivity to sunlight and high likelihood of skin cancer.


How many polypeptide chains are in a protein?

There is one polypeptide chain in a single protein chain. Polypeptides refer to short protein chains - for example insulin is a 53 amino acid protein and is considered a large polypeptide. Complex multi-component [strand] protein coalescences exist - each uniquely identified component protein strand is called - of course - a subunit: two subunits is called a dimer, three subunits is called a trimer, four is a tetramer etc. A Protein is a string of Pearls {Amino Acids} of which [out of the quadrillion possible] there are ONLY Twenty Biologically Active Types ( with two, sometimes three, more reserved for special occasions ). A common example of a biological multi-strand protein grouping is: 4 strands will combine thusly - 2 strands of one type and 2 strands of another type.
