Question

Which statement does not describe a fundamental feature of DNA replication?

It is semiconservative.

It requires a template.

It involves polymerizing deoxyribonucleotides only.

It begins at a DNA location known as an origin.

Answer 1

Answer

According to the given question-

DNA replication is the the biological process where a single molecule of double stranded DNA molecule divided into two identical copy of parental DNA double helix during cell division. It involves several steps such as-

(1) formation of replication fork

(2) initiation- when the primer binds with the initiation site

(3) elongation- with the help of DNA polymerase

(4) termination

DNA double helix is mede up of two strand which are complementary to each other. And each strand are first separated during DNA replication and work as a template strand for the New synthesis DNA strand so due to which the new strand are formed have one new strand while one original strand this is called semiconservative mode of replication. Replication started in the dna at a specific region called original of replication.after formation of replication fork with the help of enzyme helicase the protein attached to the site of initiation and here DNA polymerase synthesised the new strand by adding the nucleotides which are complementary to other nucleotides of DNA.

So considering each options the DNA replication is semiconservative, it requires template, it begins at origin of replication but it involves polymerization of nucleotides or deoxyribonucleotides triphosphate such as dGTP, dCTP, dATP, dTTP not only deoxyribonucleotides.

So the polymerizing deoxyribonucleotides only is not the fundamental features of DNA replication.
