DNA and RNA

Front

What is the structure of RNA?

Back

RNA is single-stranded, consisting of a ribose sugar, phosphate group, and nitrogenous bases (adenine, uracil, cytosine, guanine).

Front

What is the process called when DNA makes an exact copy of itself?

Back

Replication is the process by which DNA makes an exact copy of itself.

Front

What is the first stage of mitosis?

Back

Prophase is the first stage of mitosis where chromosomes condense and become visible.

Front

What base pairs with adenine in DNA?

Back

Thymine pairs with adenine in DNA.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine, thymine, cytosine, and guanine.

Front

What is the role of messenger RNA (mRNA)?

Back

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

Front

What is transcription?

Back

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

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 function of ribosomal RNA (rRNA)?

Back

rRNA forms the core of ribosome's structure and catalyzes protein synthesis.

Front

What is the role of transfer RNA (tRNA)?

Back

tRNA transports amino acids to the ribosome during protein synthesis.
