DNA & RNA

Front

What are the main functions of DNA?

Back

To store and transmit genetic information.

Front

What are the four nucleotide bases found in DNA?

Back

Adenine (A), Cytosine (C), Guanine (G), and Thymine (T).

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What is the role of DNA polymerase?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides to a growing chain.

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the double helix structure of DNA, separating the two strands.

Front

What is the function of ligase in DNA replication?

Back

Ligase is an enzyme that joins Okazaki fragments on the lagging strand during DNA replication.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What are the three main types of RNA?

Back

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 information from DNA to the ribosome, where proteins are synthesized.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome and matches them to the codons on the mRNA.
