Review Quiz on DNA Structure and Replication

Why is DNA replication considered to be semi-conservative

• Because it involves mixing of genetic material from different organisms.

• Because it only conserves half of the genetic information during the process.

• Because it results in the complete replacement of old DNA with new DNA strands.

• Because
  each new DNA molecule contains one original strand and one newly synthesized strand.

Which image is the correct structure of a Nucleotide

• 
• 
• 
• 

A biomolecule that serve as the genetic material for living organisms that consist of long chains of nucleotides that are composed of a sugar, a phosphate group, and a nitrogenous base.

Which image serves as a representation for RNA

• 
• 
• 
• 

The basic building block of nucleic acids, consisting of a sugar molecule, a phosphate group, and a nitrogenous base.

Summarize the process of DNA replication and explain the significance of this process.

• The process of making an identical copy of DNA, which ensures faithful transmission of genetic information during cell division

• DNA replication involves the synthesis of RNA molecules to transcribe genetic information

• The process by which cells generate energy by breaking down DNA molecules.

• DNA replication refers to the repair of damaged DNA strands within the cell.
