When it comes to the transmission of genetic information within living

organisms, which of the following statements are false?

A) A segment of double-stranded DNA containing 15% adenine bases will also

contain 15% thymine bases

B) DNA replication proceeds in a fully conservative manner

C) Base substitutions occurring at the third position in a codon does not

always result in the attachment of the wrong amino acid

D) Telomerase counteracts

Click to reveal answer

Answer B is correct because the process of double-stranded DNA

replication is such that one of the parent strands is joined to one new daughter

strand. This is known as semiconservative replication. Fully conservative replication

would occur if the parent strands remain together after replication has occurred.
