DNA and RNA

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms.

Front

What is RNA?

Back

RNA (Ribonucleic Acid) is a molecule that plays a crucial role in coding, decoding, regulation, and expression of genes.

Front

What are the main components of DNA?

Back

The main components of DNA are nucleotides, which consist of a sugar (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine).

Front

What are the main components of RNA?

Back

The main components of RNA are nucleotides, which consist of a sugar (ribose), a phosphate group, and a nitrogenous base (adenine, uracil, cytosine, or guanine).

Front

What is the base pairing rule in DNA?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is the base pairing rule in RNA?

Back

In RNA, adenine pairs with uracil (A-U) and cytosine pairs with guanine (C-G).

Front

What is the function of DNA?

Back

The function of DNA is to store and transmit genetic information.

Front

What is the function of RNA?

Back

The function of RNA is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

Front

How many strands does DNA have?

Back

DNA is double-stranded, forming a double helix structure.

Front

How many strands does RNA have?

Back

RNA is typically single-stranded.
