Front

Why is the order of amino acids important in protein synthesis?

Back

The order of amino acids dictates what shape the protein will fold into.

Front

Where is DNA located in a eukaryotic cell?

Front

What is the probability of two heterozygous long-tongued frogs producing short-tongued offspring?

Back

25%.

Front

What is nondisjunction in meiosis?

Back

Failure of homologous chromosomes to separate, resulting in gametes with an extra or missing chromosome.

Front

Define homologous chromosomes.

Back

Chromosomes that are similar in shape, size, and genetic content, one inherited from each parent.

Front

What is the role of the ribosome in protein synthesis?

Back

Ribosomes are the sites where amino acids are assembled into proteins.

Front

Explain the significance of transcription in gene expression.

Back

Transcription is the process of copying a segment of DNA into RNA, which is essential for protein synthesis.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype is the observable traits.

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
