Heredity
This molecule carries hereditary information in most organisms.
What is DNA?
This is a permanent change in the DNA sequence.
What is a mutation?
This type of organism or agent causes infectious disease.
What is a pathogen?
This hormone lowers blood glucose concentration.
What is insulin?
This organelle is the main site of aerobic cellular respiration.
What is the mitochondrion?
This process produces haploid gametes from diploid cells.
What is meiosis?
This technology allows a specific DNA sequence to be rapidly amplified.
What is PCR?
These proteins bind specifically to antigens.
What are antibodies?
This disorder results from insufficient insulin production or ineffective response to insulin.
What is diabetes?
This term describes the maintenance of a relatively stable internal environment.
What is homeostasis?
During this meiotic process, homologous chromosomes exchange sections of DNA.
What is crossing over?
This technique separates DNA fragments according to size using an electric field.
What is gel electrophoresis?
These white blood cells can differentiate into plasma cells that secrete antibodies.
What are B lymphocytes?
Prolonged exposure to this form of radiation is a major environmental risk factor for skin cancer.
What is ultraviolet radiation?
This type of feedback reverses a change and returns a variable towards its normal range.
What is negative feedback?
This inheritance pattern occurs when both alleles are fully expressed in a heterozygote.
What is codominance?
his genetic technology uses guide RNA and an enzyme such as Cas9 to target DNA.
What is CRISPR-Cas9?
Vaccination produces this type of immunity by deliberately exposing the immune system to an antigen.
What is artificial active immunity?
This epidemiological measure describes the number of new cases occurring within a population during a particular period.
What is incidence?
This term describes programmed cell death.
What is apoptosis?
Failure of homologous chromosomes or sister chromatids to separate correctly can produce aneuploid gametes.
What is nondisjunction?
The insertion of human insulin DNA into bacterial plasmids is an example of this technology.
What is recombinant DNA technology?
This immune response is faster and stronger after a second exposure because of long-lived lymphocytes.
What is the secondary immune response?
This study design compares people with a condition to people without it and investigates previous exposures.
What is a case-control study?
This enzyme synthesises RNA from a DNA template.
What is RNA polymerase?
