Answer:
25% of the heterozygous cross are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will always display the dominant trait (phenotype), because they are heterozygous.
Explanation:
In this explanation, I'm assuming that the allele "T" for tall plants is dominant to the allele "t" for short plants, like in Gregor Mendel's pea plant experiment.
A homozygous tall pea plant will have the genotype "TT" and a homozygous short plant will have the genotype "tt" because homozygous means that both alleles are identical. Since "T" is dominant over "t", any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is. Let's look at a Punnett square for this cross:

The DNA replication products visualized during the sanger method of DNA sequencing are observed in which nucleotides are added.
Sanger sequencing is based on the process of DNA replication. A scientist creates a copy of his DNA strand. Then observe which nucleotides have been added. This way you can see the sequence of nucleotides. A laser excites the fluorescent labels in each band and a computer detects the resulting light.
Sanger sequencing produces extension products of various lengths ending in dideoxynucleotides at the 3' ends. Extension products are separated by capillary electrophoresis or CE. Molecules are injected by an electric current into a long glass capillary filled with gel polymer. Selective incorporation of chain-terminating dideoxynucleotides by DNA polymerases during in vitro DNA replication.

The best answer - dermal tissue.
Dermal tissue in plants forms the first line of defense against physical damage and infection from the outside world.
Dermal tissue covers the outside of the plant, except in woody shrubs and trees, which have bark. The most common cell type in dermal tissue is epidermal cell. Generally, a thin waxy layer called a cuticle covers the epidermal cells and protects them.
Other cells in the dermal tissue are guard cells that surround the stomata, which are openings in the leaves. Gases enter and leave the dermal tissue through the stomata.
