Reproduction
Two parents provide genes to the offspring in this type of reproduction
What is sexual reproduction?
Chromosomes line up in the centre of the cell during this phase
What is metaphase?
mRNA is produced in this process
What is transcription?
This term describes a person's genetic makeup for a trait
What is genotype?
Radiation, diet and poisons are all types of this
What is a mutagen?
Ova travel down these structures before reaching the uterus
What are the Fallopian tubes?
Most humans have 23 of these
What are pairs of homologous chromosomes?
This DNA base is replaced with uracil in RNA
What is thymine?
A person with the blood type O has this genotype
What is OO?
A mutation in this type of cell may be passed on
What is a germ-line cell?
This type of reproduction is most common in aquatic organisms
What is external fertilisation?
This enzyme unwinds DNA
What is DNA helicase?
This small organelle is made of two subunits and is essential in translation
What is a ribosome?
This formula is used to determine allele frequency
What is allele frequency = copies of allele/copies of gene?
These sections of genes will be used in translation
What are exons?
Fungi may use these structures for asexual reproduction
What are spores?
Crossing over occurs during this phase
What is prophase I?
The codon AUG codes for this amino acid
What is methionine?
A carrier female would normally be shown this way on a pedigree
What is a half-filled circle?
This class of mutation is likely to affect multiple amino acids
What is a frameshift mutation?
Bacteria use this type of asexual reproduction
What is binary fission?
These short sections of DNA are formed on the lagging strand
What are Okozaki fragments?
Secondary protein structure consists of these two shapes
What are α-helices and β-pleated sheets?
This is the complete set of genes within a species within a location
What is gene pool?
One base is replaced by another in this type of mutation
What is a substitution?
