DNA, RNA, and Protein Synthesis

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides, which include a 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

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is transcription in the context of protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA.

Front

What is the function of transfer RNA (tRNA)?

Back

tRNA transports amino acids to the ribosome during protein synthesis.

Front

What type of bond holds the nitrogenous bases together in DNA?

Back

Hydrogen bonds hold the nitrogenous bases together in the DNA double helix.

Front

What is the complementary base pairing rule in DNA?

Back

Adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.
