The tissue you are referring to here is the xylem, a <u>vascular tissue</u>, whose basic function is to transport water and nutrients from the roots to the rest of the plant.
Adenine which is a purine base, always pairs with the pyrimidine Thymine in DNA and Uracil(also a pyrimidine) in RNA. The bond which is present between the two bases is a double hydrogen bond.
Guanine which is also a purine base, always pairs with the pyrimidine Cytosine, in the case of both, DNA and RNA. The bond which is present between the two bases is a triple hydrogen bond and hence, is stronger than the A-G double bond.
Answer:
CH4
Explanation:
Combining hydrogen and carbon produces a group of organic compounds called hydrocarbons. Depending on the specific molecular formula, there can be many different types of hydrocarbons, such as the fuels propane and octane. The simplest hydrocarbon is methane, which has the chemical formula CH4.
The enzyme, RNA polymerase, which performs the transcription process, binds to the promoter sequence and then beings to work its way down the DNA segment, constructing RNA to match the DNA nucleotides over which the enzyme passes.
