DNA&RNA

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life, determining the characteristics of living organisms.

Front

What is the primary function of DNA?

Back

The primary function of DNA is to store and transmit genetic information that directs the synthesis of proteins.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do nitrogenous bases pair in DNA?

Back

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

Front

What is the structure of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder, with two strands running in opposite directions.

Front

What is RNA?

Back

RNA (Ribonucleic Acid) is a molecule that plays a crucial role in the synthesis of proteins and can also carry genetic information.

Front

What are the main types of RNA?

Back

The main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic code from DNA to the ribosome, where proteins are synthesized.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports specific amino acids to the ribosome during protein synthesis, matching them to the corresponding codons on the mRNA.
