DNA, RNA

Front

What is the primary difference between RNA and DNA?

Back

RNA contains ribose sugar, while DNA contains deoxyribose sugar. RNA is usually single-stranded, whereas DNA is double-stranded.

Front

What are the base pairing rules in DNA?

Back

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) carries amino acids to the ribosomes, where proteins are synthesized.

Front

Where is DNA primarily located in eukaryotic cells?

Back

In eukaryotic cells, DNA is primarily located in the nucleus.

Front

What does mRNA stand for and what is its role?

Back

mRNA stands for messenger RNA, and its role is to carry genetic information from DNA to the ribosomes for protein synthesis.

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

How does the structure of RNA differ from that of DNA?

Back

RNA is single-stranded and contains uracil (U) instead of thymine (T), while DNA is double-stranded and contains thymine.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that assembles amino acids into proteins based on the sequence of mRNA.

Front

What is transcription in the context of DNA and RNA?

Back

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

Front

What is translation in the context of protein synthesis?

Back

Translation is the process by which ribosomes read mRNA sequences to synthesize proteins by linking amino acids together.
