Question
The table below shows a list of statements about DNA replication. Some of th
statements are incorrect.
TASK #1: Use a cross to identify the statements which are incorrect
DNA replication
The DNA molecule unwinds
Hydrogen bonds between the base
pairs break
Free RNA nucleotides join to bases
on the exposed DNA strands
Both polypeptide strands acts as a
template
Hydrogen bonds form between
complementary bases
Three hydrogen bonds form between
bases adenine and thymine
DNA polymerase links the new
nucleotides
Covalent bonds form between the
phosphate of one nucleotide and the
pentose sugar of the next nucleotide
Incorrect statement
I
Answer
The DNA molecule unwinds, Free RNA nucleotides join to bases on the exposed DNA strands, Three hydrogen bonds form between bases adenine and thymine.
