2023 Genetics Assessment

Front

What is a mutation?

Back

A mutation is a change in a genetic sequence, which can involve insertion, deletion, or substitution of nucleotides.

Front

Describe the structure of a DNA molecule.

Back

A DNA molecule is structured as a double helix, consisting of two strands that coil around each other.

Front

What sugar is found in RNA?

Back

RNA contains the sugar ribose.

Front

What is the resulting mRNA from the DNA sequence GAT-TAC-AGA-TTA-CAT?

Back

The resulting mRNA is CUA-AUG-UCU-AAU-GUA.

Front

How many amino acids are found on one tRNA?

Back

One tRNA carries one amino acid.

Front

What are the three types of mutations?

Back

The three types of mutations are insertion, deletion, and substitution.

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 DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded, while RNA contains ribose sugar and is single-stranded.

Front

What is the function of tRNA?

Back

tRNA transports specific amino acids to the ribosome during protein synthesis.

Front

What is a codon?

Back

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