DNA Replication & Protein Synthesis Review

Front

What is the Central Dogma of molecular biology?

Back

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

Front

What is the role of DNA Helicase in DNA replication?

Back

DNA Helicase is an enzyme that unwinds and unzips the DNA double helix, allowing the replication process to occur.

Front

What determines an organism's traits?

Back

The sequence of nitrogen bases in DNA determines an organism's traits.

Front

What is the complementary mRNA sequence for the DNA sequence TAG, CAT, AAT?

Back

The complementary mRNA sequence is AUC, GUA, UUA.

Front

What is transcription in the context of protein synthesis?

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 protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins by reading the sequence of mRNA and assembling the corresponding amino acids.

Front

What are nitrogen bases?

Back

Nitrogen bases are the building blocks of DNA and RNA, consisting of adenine (A), thymine (T), cytosine (C), guanine (G), and uracil (U) in RNA.

Front

What is the function of DNA polymerase?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand during DNA replication.

Front

What is the sugar-phosphate backbone?

Back

The sugar-phosphate backbone is the structural framework of DNA and RNA, consisting of alternating sugar and phosphate groups.

Front

What is the difference between DNA and RNA?

Back

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