Genetic Substance Quiz (English)

What is the process by which DNA is copied into mRNA?

• Translation

• Replication

• Transformation

• Transcription

Which molecule carries amino acids to the ribosome during translation?

• mRNA

• rRNA

• tRNA

• DNA

What is the function of tRNA in protein synthesis?

• tRNA acts as a catalyst in protein synthesis.

• tRNA functions to deliver amino acids to the ribosome for protein synthesis.

• tRNA functions to break down proteins during synthesis.

• tRNA is responsible for DNA replication in protein synthesis.

Where does translation occur within the cell?

• mitochondria

• lysosomes

• endoplasmic reticulum

• ribosomes

What is the role of ribosomes in protein synthesis?

• Ribosomes synthesize proteins by reading the mRNA sequence and linking amino acids together.

• Ribosomes regulate cell division

• Ribosomes break down proteins into amino acids

• Ribosomes store genetic information

What is the genetic code and how is it read during translation?

• Translation occurs in the nucleus of the cell.

• The genetic code is read during translation in groups of three nucleotides called codons, where each codon corresponds to a specific amino acid or a stop signal.

• Each codon corresponds to a specific DNA base pair.

• The genetic code is read during translation in groups of two nucleotides called codons.

How many chromosomes are typically found in a human cell?

• 23

• 46

• 50

• 64

What is the basic unit of heredity?

• nucleotide

• chromosome

• gene

• allele

What are the building blocks of proteins?

• Fatty acids

• Nucleotides

• Carbohydrates

• Amino acids

What is the relationship between genes and proteins?

• Genes provide the instructions for synthesizing proteins.

• Proteins are not encoded by genes

• Genes and proteins have no relationship

• Genes are not involved in protein synthesis
