It was the only member of the family Thylacinidae to survive into modern times.
It was widespread over continental Australia, extending north to New Guinea and south to Tasmania.
It is an apex predator that hunted kangaroos and other prey.

What is RNA?

It is a complex compound of high molecular weight that functions in cellular protein synthesis.
It replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses.
It consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds.
The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil.
It is a single-stranded molecule that carries genetic information.
RNA synthesises the panoply of proteins that an organism requires to live and works to regulate cell metabolism.

Q1) What is the structure of DNA?

The deoxyribonucleic acid (DNA ) has a double-helix structure, which resembles a twisted ladder or spiral staircase. It consists of two long chains of nucleotides running in opposite directions and bonded together by pairs of nitrogenous bases. The four nitrogenous bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
