Adenosine
Which type of nucleic acid contains uracil instead of thymine?
DNA
Carbohydrate
RNA
Protein
What is the function of DNA polymerase in DNA replication?
To synthesize new DNA strands by adding complementary nucleotides
To regulate gene expression
To break down DNA strands into nucleotides
To repair damaged DNA
What is the shape of the DNA molecule?
Double helix
Triangle
Square
Single strand
What is the role of RNA in protein synthesis?
RNA is responsible for breaking down proteins during synthesis.
RNA acts as a barrier preventing protein synthesis.
RNA carries genetic information from DNA to the ribosomes for protein synthesis.
RNA transports proteins from the ribosomes to DNA.
What is the sugar-phosphate backbone of DNA made of?
Alternating sugar (deoxyribose) and phosphate molecules
Only sugar molecules
Phosphate and nitrogen molecules
Alternating nitrogen and phosphate molecules
What is the difference between DNA and RNA structure?
DNA is double-stranded with deoxyribose sugar and thymine base, while RNA is single-stranded with ribose sugar and uracil base.
DNA and RNA are both double-stranded with deoxyribose sugar and thymine base.
DNA and RNA have the same structure but differ in function.
DNA is single-stranded with ribose sugar and thymine base, while RNA is double-stranded with deoxyribose sugar and uracil base.
If the DNA code is 'GCTA', what would be the complementary code?
CGAT
AGCT
TCGA
ATCG
What molecules are in nucleotides?
Phosphate group
Protein
Sugar
lipid
Nitrogenous base
Why are the nucleotides so gosh darn important? (Careful, all statements are true! Make sure you are picking what makes them IMPORTANT!!!!)
They hold the DNA together.
They live in the nucleus.
This is the chemical part that CODES for life.
There are 5 different kinds.
Which bases are only found in DNA?
Thymine
Cytosine
Adenine
Uracil
Guanine
ATG TGA CAG
