Back

50%.

Front

What is the correct complementary strand for the DNA sequence ATCGAG?

Back

TAGCTC.

Front

Define DNA replication.

Back

The process by which a DNA molecule makes a copy of itself.

Front

What is a Punnett square used for?

Back

To predict the probability of offspring inheriting particular traits.

Front

What are alleles?

Back

Different forms of a gene that can exist at a specific locus.

Front

What is the significance of complementary base pairing in DNA?

Back

It ensures accurate replication and transcription of genetic information.

Front

What is the role of DNA polymerase in replication?

Back

It synthesizes new DNA strands by adding nucleotides complementary to the template strand.
