Question

5 multiple choice 1 point which enzyme is responsible for putting together okazaki fragments produced on the lagging strand during dna replication? dna polymerase helicase rna primase dna ligase 6 multiple choice 1 point one feature of dna replication is that it is ultra - conservative neo - conservative unidirectional semi - conservative 7 multiple choice 1 point which of the following is not a component of nucleotides, the building blocks of dna? inorganic phosphate deoxyglucose nitrogenous base deoxyribose

Explanation:

• Question 5: DNA ligase is the enzyme that joins Okazaki fragments on the lagging strand during DNA replication. DNA polymerase synthesizes DNA strands, helicase unwinds the DNA double - helix, and RNA primase synthesizes RNA primers.
• Question 6: DNA replication is semi - conservative. This means that each new DNA molecule consists of one old strand (from the original DNA molecule) and one new strand. Ultra - conservative and neo - conservative are not the correct terms for DNA replication, and DNA replication is bidirectional in most organisms.
• Question 7: Nucleotides, the building blocks of DNA, consist of a nitrogenous base, deoxyribose (a 5 - carbon sugar), and an inorganic phosphate. Deoxyglucose is not a component of DNA nucleotides.

Answer:

1. DNA ligase
2. semi - conservative
3. deoxyglucose
