GENETICS REVIEW

Front

What is a codon?

Back

A codon is a three-base sequence of mRNA that codes for a single amino acid.

Front

From which parent do sons inherit recessive, X-linked traits?

Back

Sons inherit recessive, X-linked traits from their mother.

Front

What must the genotype of an individual with a recessive disorder be if they express the disorder?

Back

The genotype must be 'hh'.

Front

What molecule is produced during transcription?

Back

mRNA (messenger RNA) is produced during transcription.

Front

What is the process of translation?

Back

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

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during translation.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is a pedigree chart used for?

Back

A pedigree chart is used to track the inheritance of traits across generations.

Front

What is the function of ribosomes in cells?

Back

Ribosomes are the sites of protein synthesis in cells.

Front

What is the significance of mutations in genetics?

Back

Mutations can lead to changes in protein structure and function, potentially causing genetic disorders.
