DNA and RNA Review

Front

Which base does not exist in RNA?

Back

Thymine (T) is not found in RNA; instead, RNA contains Uracil (U).

Front

What is a key difference between DNA and RNA?

Back

Only RNA has the base Uracil.

Front

What is the result of DNA replication?

Back

DNA replication results in two DNA molecules, each with one new strand and one original strand.

Front

What is a 3 nucleotide sequence of mRNA called?

Back

A codon.

Front

What bonds are broken during transcription?

Back

Hydrogen bonds between base pairs are broken during transcription.

Front

What are the four bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What are the four bases found in RNA?

Back

Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the function of tRNA?

Back

tRNA transports amino acids to the ribosome during protein synthesis and matches them to the codons in mRNA.

Front

What is the process of transcription?

Back

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