Ductility is a physical property.
A physical property of a material is a property that can be measured or observed without changing the composition of the material.
In this case ductility is a physical property. It is defined as the property of a material associated with the ability to be drawn or stretched into a wire without breaking. The chemical identity of the material is not affected, that is it does not change.
Example of ductile materials include gold, silver, copper, erbium, terbium and samarium.
Other examples of physical properties are:
1. Solubility
2. Melting point.
3. Boiling point.
4. Color
5. Density.
Answer:
RNA (referred to as a ribozyme)
Explanation:
The mutation must occur in the egg cell
Answer: All of the statements are true.
Explanation:
Purines are biologically synthesized as nucleotides and in particular as ribotides, that is, bases attached to ribose 5-phosphate. Adenine and guanine are both derived from the nucleotide inosine monophosphate (IMP), which is the first compound in the pathway to have a completely formed purine ring system.
Purine nucleotides can be synthesized in two distinct pathways. First, purines are synthesized de novo, starting with simple starting materials such as amino acids and bicarbonate. the purine bases are assembled already attached to the ribose ring. Alternatively, purine bases, released by the hydrolytic degradation of nucleic acids and nucleotides, can be salvaged and recycled. Purine salvage pathways are mostly noted for the energy that they save and the remarkable effects of their absence.
All statements are correct because the organization of purine synthetic enzymes involves multifunctional enzymes, reversible enzyme formations, through out the sequence there is maintenance of high local concentration and the ten steps requires only six enzymes.
The process is called interphase
