Answer:
The longest strand of DNA is the one that has descended the least in the electrophoresis gel. In other words, it is the one at the top of the gel.
Explanation:
Electrophoresis is a process that separates DNA according to its size and charge. The scientist puts the DNA samples into the indents at the top of a special gel. Then the person places it in a box that contains an ionic solution, a positive electrode at the bottom, and a negative electrode at the top. As the DNA has a negative charge, it will descend through the gel's pores towards the positive electrode. Since there are DNA of different lengths, the shortest goes down quickly through the gel than the large strands. As a result, the short strands of DNA will be at the bottom of the gel, the medium size strands will be in the middle of the gel, and the l<u>arge strands on the top of the gel</u>.
Answer:
150 individuals
Explanation:
If the dark phenotype is determined by a dominant allele at a single locus, the ratio of dark green phenotype to pale green phenotype at F2 should be 3:1 according to the Mendelian standard.
200 to 3:1 = 150:50
<u>Hence, if 200 F2 individuals were characterized, one would expect the number of dark green individuals to be 150 while the pale green would be expected to be 50.</u>
Answer:
Vascular tissue transports water, minerals, and sugars throughout the plant. Vascular tissue is made up of xylem tissue and phloem tissue. Xylem tissue transports water and nutrients from the roots upward. Phloem tissue carries sugars from the sites of photosynthesis to the rest of the plant.
