DNA and RNA

Front

What is the structure of DNA?

Back

DNA is a double helix made up of two strands of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What is the base pairing rule in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is RNA and how does it differ from DNA?

Back

RNA (Ribonucleic Acid) is single-stranded, contains ribose sugar, and has Uracil (U) instead of Thymine (T).

Front

What are the three types of RNA?

Back

Messenger RNA (mRNA), Transfer RNA (tRNA), and Ribosomal RNA (rRNA).

Front

What is the function of mRNA?

Back

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

Front

What is the role of tRNA?

Back

tRNA transports amino acids to the ribosome during protein synthesis, matching them to the mRNA codons.

Front

What is the role of rRNA?

Back

rRNA is a component of ribosomes, which are the sites of protein synthesis.

Front

What sugar is found in RNA?

Back

Ribose.

Front

What is transcription in the context of DNA and RNA?

Back

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