Front

What is the mRNA sequence that corresponds to a given DNA sequence?

Back

The mRNA sequence is complementary to the DNA template strand, replacing thymine (T) with uracil (U).

Front

What is transcription in the context of genetics?

Back

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

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the genotype of an organism with one dominant and one recessive allele?

Back

The genotype is heterozygous.

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 difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even when only one copy is present, while recessive alleles require two copies to express their traits.

Front

What is the purpose of a codon chart?

Back

A codon chart is used to determine which amino acid corresponds to a specific mRNA codon.

Front

What is the process of translation in genetics?

Back

Translation is the process where ribosomes synthesize proteins using the mRNA sequence.
