Answer:
In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.
Explanation:
The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.
The correct options in the blanks are DNA, mRNA, Protein, mRNA, and DNA respectively.
What is gene expression?It is the process by which cells produce protein from DNA molecules. DNA produces RNA which contains codes to produce amino acids.
The mRNA enters the ribosome which produced protein using the codons of mRNA.
Retroviruses have special machinery to produce the DNA from mRNA.
Therefore, the correct options in the blanks are DNA, mRNA, Protein, mRNA, and DNA respectively.

A directional flow of electric charge
Answers
Answer:
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart. Actually, electrons would go in the reverse direction across the cables.
What is electric current ?A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.
The cell phone, trains, ships, refrigerator, and the motors in appliances like food processors all run on electricity. To be useful, electric energy must be converted into other forms of energy like heat, light, or mechanical.
Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart.

A prospective groom, who is not affected by cystic fibrosis (CF), has a sister with cystic fibrosis, an autosomal recessive disease. Their parents are also not affected. The brother plans to marry a woman who has no history of CF in her family. What is the probability that they will have a child with CF? They are both Caucasian and the overall frequency of CF in the Caucasian population is 1/2500 - that is, 1 affected child per 2500 (assume the population meets the Hardy-Weinberg assumptions).
Answers
Answer: In punnett square number 1, we see the cross between AA and aa, and the result is 100% Aa individuals, so there is 0% chances of haveing a child with CF. In punnett square number 2, we see the cross between Aa and aa and there is 50% chances of having a child with CF (aa genotype).
