Put the steps of protein synthesis in order
mRNA is transcribed in the nucleus from a DNA template by RNA polymerase
mRNA exits the nucleus and enters the cytoplasm for translation
mRNA attaches to the ribosome, tRNA carries amino acids to the ribosome
tRNA matches its anticodon to the mRNA codon
tRNA adds amino acids to the chain until a stop codon is reached, forming a protein
What would deleting a nucleotide from a DNA sequence cause?
Mutation
Protein Synthesis
Replication
Regeneration

Glycine
Serine
Stop
Tryptophan
Given this RNA sequence, what amino acid would be formed: UAC
Serine
Stop
Asparagine
Tyrosine
What is deoxyribose? What is ribose?
Deoxyribose is a type of protein, while ribose is a type of lipid.
DNA has a (a) structure. It is made of (b) connected by (c) bonds. The backbone of the DNA is made of (d) that alternate.
According to Chargaff's rule, if a sample of DNA is 30% adenine, how much would be guanine?
30%
A nucleotide is made up of
nitrogen base
sugar
phosphate group
