Answer:
One fertilizes the egg, and the other combines with the two polar nuclei.
Explanation:
Hey ur answer should be A and C
the answer is A. I took the test and got it right. The question is specifically asking about the THIN filaments, making it actin- and only actin.

sorry I couldn't get to it fast enough
Explanation:
- It <em>helps in understanding and preventing genetic diseases.</em>
Genome mapping projects like the human genome project made it possible to map regions of the genome associated with disease. These regions which often arise through mutations, may be cloned and identified through diagnostic methods. This <em>helps in understanding and preventing genetic diseases, along with providing possible treatment targets in drug and gene therapeutics.
</em>
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.
Further Explanation:
During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.
