DNA vs. RNA

Front

What is the primary structural difference between DNA and RNA?

Back

DNA is double-stranded, while RNA is single-stranded.

Front

What type of sugar is found in DNA?

Back

Deoxyribose.

Front

What type of sugar is found in RNA?

Back

Ribose.

Front

What is the function of mRNA in the cell?

Back

mRNA serves as a template for protein synthesis by carrying genetic information from the DNA to the ribosome.

Front

Where is RNA primarily synthesized in the cell?

Back

RNA is primarily synthesized in the nucleus.

Front

What is the base pairing rule for RNA?

Back

In RNA, adenine pairs with uracil (A-U) and cytosine pairs with guanine (C-G).

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome and matches them to the coded mRNA message.

Front

What is the significance of the sequence AUG in mRNA?

Back

AUG is the start codon that signals the beginning of protein synthesis.

Front

How does RNA differ from DNA in terms of nitrogenous bases?

Back

RNA contains uracil (U) instead of thymine (T), which is found in DNA.

Front

What is the process of transcription?

Back

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