The researchers prepare an intron-free copy of the eukaryotic gene for the use in creating the transgenic bacteria by using the reverse transcriptase to make the cDNA from the mature mRNA
The structure of the eukaryotic genes. Most of the eukaryotic genes are contain the segments of the coding sequences (exons) that interrupted by the noncoding sequences (introns). Both the exons and the introns are transcribed to yield a long and primary RNA transcript.
Eukaryotic DNA is the linear, compacted into the chromosomes by the histones, and has the telomeres at each end to protect from the deterioration. The Prokaryotes contain the circular DNA in addition to the smaller, transferable DNA plasmids. Eukaryotic cells contain the mitochondrial DNA in the addition to the nuclear DNA

Answer:
A) polar
Explanation:
Polar molecules contains partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.
For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.
Hence, the correct answer is "A) polar".
Answer:
It does not obey Mendel's law of dominance.
Explanation:
Epistasis is not complete dominance
Answer:
La contaminación del suelo afecta a la seguridad alimentaria al reducir el rendimiento y la calidad de los cultivos Unos alimentos inocuos, nutritivos y de buena calidad solo pueden producirse si nuestros suelos se mantienen sanos. Si no lo están, no podremos producir suficientes alimentos para alcanzar el #HambreCero
Answer:
abscisic acid
Explanation:
Abscisic acid is a plant hormone also known by the acronym ABA, whose function is growth inhibition and stomatal closure. We can also attribute to abscisic acid the function of delaying seed germination in the process known as vegetable dormancy. Usually the accumulation of this hormone happens at the beginning of the development of some seeds and is related to delayed germination.
Abscisic acid induces seed dormancy, but decreasing levels of this hormone release seeds from dormancy.
