Front

What is the complementary RNA sequence for the DNA strand GTAGTCA?

Back

CAUCAGU

Front

What are the chunks of three bases in mRNA called?

Back

Codons

Front

What type of chromosomal mutation involves a segment of DNA being moved to a different location?

Back

Translocation

Front

What process converts mRNA into a polypeptide?

Back

Translation

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome for protein assembly.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes facilitate the translation of mRNA into a polypeptide chain.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.

Front

What is the difference between a point mutation and a frameshift mutation?

Back

A point mutation changes a single nucleotide, while a frameshift mutation shifts the reading frame by adding or deleting nucleotides.

Front

What is the significance of the start codon in translation?

Back

The start codon (AUG) signals the beginning of protein synthesis.
