U8T1 – Nucleic Acids Recap from Year 1

Name the components of a DNA nucleotide.

Which component of a nucleotide contains nitrogen atoms?

Name the type of reaction that joins the nucleotides together.

Name the type of bond which forms the backbone of the DNA strand.

Name the type of bond that holds the complementary base pairs together.

What does the A stand for in the genetic code?

What does the C stand for in the genetic code?

Which of the following is NOT a difference between RNA and DNA?

Name the method by which DNA replicates.

Name the enzyme that breaks the hydrogen bonds between complimentary bases during DNA replication.

What attracts new 'free' nucleotides to the exposed template strand during DNA replication?

Which two molecules does DNA Polymerase join together?

True or False: DNA polymerase requires double stranded DNA in order to initiate DNA replication

Each complementary strand of DNA runs in opposite directions. What word describes this?

The deoxyribose sugar at the end of a DNA molecule can either have a bond available to join with carbon number 3 ( 3' or 3 prime) or carbon number 5 (5' or 5 prime). DNA polymerase can only join to one end, which end can it bind to and then extend?

Which direction can DNA polymerase only extend the new strand of DNA?

If a template strand has the code starting at the 5 prime end with 5' GCTAAGCA 3'. What would be the order the bases would be added to the new strand ?

If a section of DNA contains 21% base C, what percentage will base A have?

Which of the following is a difference between prokaryotic and eukaryotic DNA?

Which type of DNA is not circular?

Which of the following is not coded for by a gene?

Which word does NOT describe the genetic code?

Which of the following carries the code for the order of amino acids?

Which word describes the sequence of three bases on DNA that code for an amino acid?

What is the position of gene on a chromosome called?
