DNA, Mutations, & Protein Synthesis

Front

What are the building blocks of DNA?

Back

Nucleotides are the units that are repeatedly joined together to form a strand of DNA.

Front

What are introns and exons in mRNA processing?

Back

Introns are non-coding regions that are removed, while exons are coding regions that are spliced together to form the final mRNA molecule.

Front

What is a Frameshift mutation?

Back

A Frameshift mutation occurs when a single base is added or deleted, changing the reading frame of the genetic code.

Front

Which enzyme is responsible for synthesizing new DNA strands?

Back

DNA Polymerase is the enzyme that builds new strands of DNA.

Front

What type of DNA replication involves one parent strand and one new strand?

Back

Semiconservative replication is the process where new DNA consists of one parent strand and one newly synthesized strand.

Front

What is the role of DNA Ligase?

Back

DNA Ligase is an enzyme that joins together Okazaki fragments on the lagging strand during DNA replication.

Front

What is the function of RNA Primase?

Back

RNA Primase synthesizes a short RNA primer that provides a starting point for DNA 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.

Front

What is transcription in protein synthesis?

Back

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

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA.
