A group of genes that work together
A group of genes that work togetherWhat is an operon?Sometimes, gene variants (also known as mutations) prevent one or more proteins from working properly. By changing a gene's instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all.Genes are contained in chromosomes, which are in
I think it would be D. Dominant
Answer:
The correct answer is b a mutation in a gene that codes for protein regulating cell division.
Explanation:
Cancer is a disease that result due unregulated cell divison.There are many tumor suppressor protein present in our body such as retinoblastoma tumor suppressor protein,p53 protein.
These tumor suppressor protein helps to carry out cell divison in a regulated fashion and send signal for division only to that cell that have undamaged DNA.
Mutation in the gene encoding tumor suppressor protein leads to development of cancer.
Life needs energy, water, heat and nutrients. Reduce the availability of one or more of those things and biodiversity generally decreases.
Tropical forests tend to be more diverse than polar ice caps. However, arctic seas tend to be more biologically interesting than the middle of the Sahara. I bet this is what your homework is looking for but it's important to remember there are counterexamples.
