What situation best represents how DNA sequencing, PCR, and gene probes might be used together? Multiple Choice Scientists might
replicate a strand of DNA using PCR before sequencing it. Once the sequence is known, they can produce a corresponding gene probe. Scientists might sequence a strand of DNA before replicating it with PCR. Once it is replicated, they can create a complementary gene probe. Scientists might create a gene probe to find the correct DNA strand to sequence. Once it is sequenced, they might replicate it with PCR.

Explanation:
PCR refers to the polymerase chain reaction that amplifies the small sample of DNA into multiple copies in three steps. These steps are denaturation of sample DNA to produce single-stranded template strand, binding of primer to the template and elongation. The multiple copies of the sample DNA are then used to decipher its sequence using various sequencing methods.
Once the sequence of the sample DNA is known, the short, single-stranded DNA molecules that are complementary to the specific sequence of DNA are formed. These single-stranded DNA molecules are called DNA probe and are used to detect the specific nucleotide sequence in some other sample DNA.
Because the fatty acid chains are saturated and unsaturated hydrocarbons, it implies that the fatty acid chains of a phospholipid is not attracted to water hence why they are turned inwards towards each other and away from aqueous medium. This implies that the interior of the membrane is HYDROPHOBIC (water-fearing/water-repelling).
The correct answer is plants with seeds are not dependent on water for reproduction. <span> Seeds contain a diploid embryo that will germinate into a sporophyte and thus it has a role to nourish and protect that embryo. The main advantage of the seeds is that it has several layers of hardened tissue which prevent desiccation and that allow them to live and reproduce without water. </span>
"<span>Appearance of a trait in a population does not solely depend on its dominant or recessive nature" is the correct choice among the choices that are given in the question. The correct option among all the options that are given in the question is the second option or option "B". I hope that the answer has helped you.</span>
Cows and other mammals produce milk to provide the food their babies need to grow. Seeds and milk contain proteins, fats, sugars and/or starch. 1. Explain how the fats, sugars and/or starch contained in seeds or milk are useful for the plant sprouting from the seed or the baby mammal.
