Hairs are mostly fibrous proteins and are composed of keratin, and also the main constituent of skin, nails, wool, woof, feathers etc.
Keratin is the essential fibrous protein which has a structural and protective functions in the epithelium.
I don’t know the first one but plants evolve from algae
GGC-CAT - strand of DNA
xxx- xxx - strand of mRNA

The first, let's see what connect with what:
when we talk about DNA and complementary strand of DNA:
guanine connects to cytosine (and vice versa)
thymine connects to adenine (and vice wersa)
when we talk about DNA and complementary strand of RNA:
guanine connects to cytosine (and vice wersa)
adenine (in DNA) connects to uracil (in RNA)
thymine (in DNA) connects to adenine (in RNA)

GGC- CAT - strand of DNA
<span>CCG- GUA - complementary strand of mRNA
</span>complementary strand of DNA would be: CCG- GTA
(in complementary strand of RNA: thymine is replaced with uracil)<span>
