HB U4P1 Central Dogma of Genetics

Front

What is the role of the Anticodon in protein synthesis?

Back

The Anticodon is a sequence of three nucleotides on tRNA that pairs with the corresponding codon on mRNA during translation, ensuring the correct amino acid is added to the growing polypeptide chain.

Front

What is the Replication Fork?

Back

The Replication Fork is the area where the double helix of DNA is unwound, allowing for the replication process to occur.

Front

What amino acid corresponds to the anticodon ACU?

Back

None; the anticodon ACU corresponds to the amino acid Threonine (not listed in the options).

Front

What is the first step in DNA replication?

Back

The first step is when DNA Helicase unwinds the original DNA strand, separating the two strands.

Front

What is the third step in DNA replication?

Back

The third step is when DNA polymerase builds new strands by bringing in new nucleotide bases.

Front

Define the Central Dogma of Genetics.

Back

The Central Dogma of Genetics describes the flow of genetic information from DNA to RNA to protein, outlining the processes of transcription and translation.

Front

What is transcription in the context of genetics?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which carries the genetic information to the ribosome.

Front

What is translation in the context of genetics?

Back

Translation is the process where ribosomes synthesize proteins by decoding the mRNA sequence into a polypeptide chain.

Front

What is the function of RNA Primase?

Back

RNA Primase synthesizes a short RNA primer that provides a starting point for DNA polymerase to begin DNA replication.

Front

What role does DNA polymerase play in DNA replication?

Back

DNA polymerase adds new nucleotide bases to the growing DNA strand, ensuring accurate replication of the DNA.
