2425 Transcription, Translation, and Mutation Test Review

Front

What is transcription in the context of DNA and RNA?

Back

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).

Front

What base pairs with adenine (A) during RNA transcription?

Back

During RNA transcription, adenine (A) pairs with uracil (U).

Front

What is the role of guanine in DNA and RNA?

Back

Guanine is one of the four main nucleobases in DNA and RNA, and it pairs with cytosine (C) through hydrogen bonds.

Front

What is the outcome of DNA replication?

Back

The outcome of DNA replication is two DNA molecules, each containing one original strand and one newly synthesized strand.

Front

What is a mutation in DNA?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is the relationship between DNA, RNA, and proteins?

Back

DNA is transcribed into RNA, which is then translated into proteins, forming the central dogma of molecular biology.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.

Front

What is the significance of the genetic code?

Back

The genetic code is the set of rules by which information encoded in DNA or RNA sequences is translated into proteins.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable physical and biochemical characteristics.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating mRNA into amino acid sequences.
