6 Questions
What is the structure of DNA?
Double stranded
What are the components of DNA nucleotides?
Deoxyribose, AT, GC, hydrogen bonds
Explain the process of DNA replication.
The existing DNA strand serves as a template for the synthesis of a new strand. DNA polymerase adds nucleotides to the 3’ end of a primer, resulting in the synthesis of a new strand that is complementary to the old one.
What is the role of DNA polymerase in DNA replication?
DNA polymerase synthesizes the new strand in the 5’ to 3’ direction and is responsible for repairing mis-matched nucleotides.
What is the significance of the antiparallel nature of DNA strands?
The antiparallel nature ensures that one strand starts with 5’ ribose and the opposite strand starts with 3’ ribose, allowing for complementary base pairing.
What are the differences between DNA and RNA?
DNA is double-stranded with deoxyribose, AT, and GC, while RNA is single-stranded with ribose, GC, and AU.
Test your knowledge of nucleic acids, DNA and RNA structures, including their places in the nucleus, mitochondrion, and chloroplast. Understand the differences between these two types of nucleic acids, their components, and characteristics such as double-stranded DNA with deoxyribose and single-stranded RNA with ribose.
