Every one of us started out as a single cell that contained all our . the of each cell contains chromosomes. chromosomes are , which is . each cell contains pairs of chromosomes. are short segments of dna. they direct cells to . the human genome consists of . they also interact with . therefore, whether a gene is active or not is caused by .

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.

linnaeus is the father of taxonomy, which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
