Answer:
5'GATCGTAA3'
5'ATTCTAGA3'
Explanation:
As requested in the question above, the primers were presented with 8 nucleotides, with the nitrogenous bases of the DNA, and in the 5'-3 'direction.
Primers are small fragments of DNA that are used by DNA polymerase to form new strands. The primes attach to pieces on the ribbon, through the complementarity of the nitrogenous bases, serving as a template for the DNA polymerase to create the new ribbon.
DNA polymerase uses primers at the origin of replication, and can follow the path from the right or from the left, depending on the primers used, for this reason, this question has two answers.
The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes
The correct answer is "All of the above are correct"
Answer:
Meiosis and Genetic Variation.
Explanation:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. It results in new combinations of genes on each chromosome.
When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.
In sexual reproduction, two gametes unite to produce an offspring. But which two of the millions of possible gametes will it be? This is likely to be a matter of chance. It is obviously another source of genetic variation in offspring. This is known as random fertilization.
<span>The circulatory body system, otherwise known as the cardiovascular or vascular system, is composed of four major parts: the heart, arteries, and veins. The vital responsibilities of the said system is to circulate blood throughout the body, transport nutrients, and carry away waste for elimination. Circulation starts when the heart pumps out blood through the main artery aorta, into the lung capillaries for oxygenation, and throughout the body via the arteries. Besides oxygen, nutrients and metabolic products are distributed as blood circulates, waste is processed and soon after eliminated by the kidneys as blood circulates there, and un-oxygenated blood returns to the heart through the superior and inferior vena cava (veins), the whole cycle therefore carrying on.</span>
