H DNA Replication and Protein Synthesis Review

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA, allowing genetic information to be passed on during cell division.

Front

What is the leading strand in DNA replication?

Back

The leading strand is the DNA strand that is synthesized continuously in the 5' to 3' direction during DNA replication.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

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 start codon and its significance?

Back

The start codon is AUG, which signals the beginning of translation and codes for the amino acid methionine.

Front

What is translation in the context of protein synthesis?

Back

Translation is the process of converting the sequence of nucleotides in mRNA into a sequence of amino acids to form a protein.

Front

What is a terminator sequence in DNA?

Back

A terminator sequence is a specific sequence of nucleotides in DNA that signals the end of transcription.

Front

What is the difference between the leading strand and the lagging strand in DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, facilitating the assembly of amino acids into proteins.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome during translation, matching them to the corresponding codons in mRNA.
