DNA
This is the shape of DNA.
What is a double helix?
RNA is single- or double-stranded?
What is single-stranded?
This is a segment of DNA that codes for a trait.
What is a gene?
A mutation is a change in this molecule.
What is DNA?
Protein synthesis occurs at this organelle.
What is the ribosome?
DNA stands for this.
What is deoxyribonucleic acid?
RNA contains this sugar instead of deoxyribose.
Ribose
When one allele hides another, the allele that is shown is called this.
What is dominant?
This type of mutation involves one base being replaced by another.
What is substitution?
This is the first step of protein synthesis where DNA is copied into RNA.
What is transcription?
These are the four nitrogen bases in DNA.
What are adenine, thymine, cytosine, and guanine?
This base replaces adenine in RNA.
What is uracil?
This is the physical appearance of a trait.
What is phenotype?
This mutation adds an extra base into the sequence.
What is insertion?
This is the second step where mRNA is used to build a protein.
What is translation?
This base pairs with adenine in DNA.
What is thymine?
This type of RNA carries amino acids to the ribosome.
What is tRNA?
This is the genetic makeup of an organism.
What is genotype?
This mutation removes a base from the sequence.
What is deletion?
A group of three bases on mRNA is called this.
What is a codon?
This part of the cell contains DNA in eukaryotes.
What is the nucleus?
This type of RNA carries the genetic message from DNA.
What is mRNA?
Different versions of the same gene are called this.
What are alleles?
nsertions and deletions often cause this type of mutation that shifts the reading frame.
What is a frameshift mutation?
This molecule brings amino acids to the ribosome during translation.
What is tRNA?
