RNA & Transcription

Front

What is RNA?

Back

RNA (Ribonucleic Acid) is a molecule that plays a crucial role in coding, decoding, regulation, and expression of genes. It is usually single-stranded and contains the base uracil instead of thymine.

What is the primary function of mRNA?

Back

mRNA (messenger RNA) provides the information from DNA to ribosomes for protein synthesis.

Front

What is transcription?

Back

Transcription is the process of making a complementary mRNA strand from a DNA template.

Front

Is RNA double-stranded?

Back

No, RNA is usually single-stranded.

Front

What is the first step of protein synthesis?

Back

The first step of protein synthesis is transcription.

Front

What are the three main types of RNA?

Back

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

Front

What role does tRNA play in protein synthesis?

Back

tRNA (transfer RNA) transfers amino acids to the ribosomes during protein synthesis.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of creating mRNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into polypeptide chains.

Front

What is the significance of the base uracil in RNA?

Back

Uracil replaces thymine in RNA and pairs with adenine during the formation of RNA.
