Answer:
Chromosome is basically made of DNA and proteins.
Explanation:
Chromosomes contain thread like structure present inside the nucleus of the cell.Chromosome is generally made of DNA and proteins(Histone proteins).
The DNA is wrapped around the basic protein histone to provide support the chromosome structure.
The wrapping of DNA around the histone proteins helps in the formation of nucleosome which helps in the packing of DNA inside the chromosome.
The metal properties that make up electrical wires are conductivity and ductility. Conductivity is important for free electrons to flow, hence electricity. Ductility is as well integral for strips to be formed, but with ample strength that does not break the material.

Answer:
Non metals join to form covalent bond.
Explanation:
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
Both atoms bonded through covalent bond.
In Cl₂ both chlorine atoms are bonded through the covalent bond.
