DNA, RNA, and Protein Synthesis

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unzips the DNA double helix to prepare for replication.

Front

Where does transcription occur in a cell?

Back

Transcription takes place in the nucleus.

Front

What is a key characteristic of RNA?

Back

RNA is usually single stranded and contains the base uracil.

Front

What are the correct complementary base pairs in DNA?

Back

The correct complementary base pairs are A-T and G-C.

Front

What are the components of a nucleotide?

Back

A nucleotide is made of a sugar, a phosphate group, and a nitrogen base.

Front

What is the function of messenger RNA (mRNA)?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA is double stranded and contains thymine, while RNA is single stranded and contains uracil.

Front

What is the process of transcription?

Back

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

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins from mRNA.

Front

What is the significance of the genetic code?

Back

The genetic code determines how sequences of nucleotides in DNA are translated into amino acids.
