What are mitochondrial myopathies?
a group of neuromuscular disorders that result from defects in the function of the mitochondrion, a small organelle located inside many cells that are responsible for fulfilling energy requirements of the tissue
What are two environmental factors that can cause mutations?
Ultraviolet radiation from the sun and certain chemicals in the environment, such as those found in tobacco smoke or industrial pollutants, are known to cause mutations in DNA. These mutations can potentially lead to genetic disorders or an increased risk of cancer.
Why do mutations in gene affect traits?
Genes produce proteins that cause traits.
How mutations in reproductive cells are different from mutations in body cells?
Mutations in reproductive cells can be passed on to offspring, potentially impacting future generations, while mutations in body cells typically affect only the individual in which they occur. Reproductive cell mutations can lead to genetic disorders in offspring, while mutations in body cells may cause diseases or cancer in the individual.
What do mutations cause in genotype and phenotype?
Mutations can cause changes in the genotype by altering the DNA sequence. These changes can then affect the phenotype by influencing the expression of certain traits or characteristics in an organism.
What do mutations in genes cause?
Mutations in genes can cause changes in the structure or function of the corresponding proteins, leading to various outcomes such as genetic disorders, cancer, or altered traits. Mutations can disrupt normal cellular processes, affect gene regulation, or result in the production of abnormal proteins.
What are some of possible consequence of mutations?
DNA mutations can cause genetic disorders such as cancer, Diabetes, and Asthma.
Mutagenic agents are substances that?
Mutagenic agents are substances that can cause changes in an organism's DNA, leading to mutations. These mutations can affect the way cells grow and replicate, potentially causing harmful effects such as cancer or genetic disorders.
How was the identification of nDNA mutations that cause mitochondrial myopathies first made?
first made when a nuclear gene involved in mtDNA replication was found to be defective in a disorder involving a patient with a mitochondrial myopathy
How can mutations affect protein synthesis?
it can cause cancer
What hereditary red blood cell disorders may cause hemolysis?
There are many genetic mutations that affect the hemoglobin itself, the best-known of which is sickle cell disease. Such hereditary disorders as spherocytosis weaken the outer membrane of the red cell.
How does a mutation in a sex cell differ from a mutation in a non-sex cell?
Mutations in sex cells can be passed on to children. Mutations in sex cells only affect offspring. Mutations in sex cells do not affect the organism.
What are mitochondrial myopathies?

Do mutations in genes affect traits?
Genes produce proteins that cause traits.
What causes the MPS I disorders?
Mutations in the alpha-L-iduronidase (IDUA) gene located on chromosome 4 cause the MPS I disorders (Hurler, Hurler-Scheie, and Scheie syndromes
