DNA Processes: Replication, Transcription, Translation

Front

What is DNA replication?

Back

The process by which a DNA molecule makes a copy of itself, resulting in two identical DNA strands.

Front

What is transcription in the context of DNA processes?

Back

The process of synthesizing RNA from a DNA template, where the DNA sequence is converted into a complementary RNA sequence.

Front

What is translation in the context of protein synthesis?

Back

The process by which ribosomes synthesize proteins using the mRNA sequence as a template.

Front

What are the base pairing rules for RNA?

Back

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

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the significance of the start codon in translation?

Back

The start codon (AUG) signals the beginning of protein synthesis and codes for the amino acid methionine.

Front

What is the end product of transcription?

Back

The end product of transcription is a single strand of mRNA that is complementary to the DNA template.

Front

What is the function of tRNA in translation?

Back

tRNA (transfer RNA) brings the appropriate amino acids to the ribosome during protein synthesis, matching them to the mRNA codons.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.

Front

What is the difference between DNA and RNA?

Back

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