Insulin is a hormone produced by some pancreatic cells. Scientists have isolated the DNA sequence that codes for human insulin production Which of the following best predicts the effect of inserting this gene into the DNA of a bacterial cell?
А) The recombinant bacterium will produce human insulin using its own transcription and translation machinery.
B) The recombinant bacterium will not transcribe the human insulin gene because this gene is not normally found in the bacterial genome.
C) The recombinant bacterium will transcribe the gene but will be unable to translate the mRNA.
D) The recombinant bacterium will die because it has been exposed to foreign DNA.
Answer:
А) The recombinant bacterium will produce human insulin using its own transcription and translation machinery.
Explanation:
Recombinant DNA technologies refer to molecular biology techniques used to create chimeric DNA sequences by using genetic recombination techniques. The resultant recombinant DNA can further be used for the production of desired gene products (proteins) both in vitro and in living organisms. DNA recombinant techniques involve the insertion of desired DNA regions into an appropriate vector such as, for example, in a plasmid that is amplified in bacteria. For this purpose, the desired DNA fragment is inserted into a plasmid vector by digesting both the target DNA and plasmid insertion sites with an appropriate restriction enzyme. Subsequently, a DNA ligase is used to join both DNA fragments from their ends. Finally, the transformed bacterial (host) cells are selected to express the desired inserted gene.
How did Wegener use the similar mountain ranges and areas made of certain types of rock found
Africa and South America as evidence that these two continents were once connected?
Answer:
Due to similar chemical composition of rocks of both continents.
Explanation:
Wegener use the similar mountain ranges and areas as evidence that these two continents i. e. Africa and South America were once connected because of their same chemical composition of rocks. Before 175 million years ago all the continents are joined with each other which we called as supercontinent. Due to this, we can say that Africa and South America is also connected to each other and having same rock chemical composition.
Black mice and tan mice are native species that are observed in a particular region. Human habitation in the region caused an invasive mouse species to enter the region. These mice are brown and share the same food requirements as black mice. Tan mice have different food requirements. How will this change affect the food web in the region? A. The availability of food resources for black mice and brown mice will decrease. B. The population of tan mice will decrease. C. The black mice and tan mice will compete for food resources. D. The tan mice and brown mice will compete for food resources.
Answer:
A
Explanation:
The correct answer would be that the availability of food resources for black mice and brown mice will decrease.
Since the food requirements of the black mice are the same as that of the invasive brown mice, the available food supply that used to be only for the black mice would now be shared by the two strains of mice. Hence, the available food for the two groups of mice will naturally decrease.
There is no sufficient information to conclude that the population of tan mice will decrease, hence, option B is incorrect.
The black mice and tan mice have different food requirements going by the information available in the illustration, hence, both cannot compete for food resources. Option C is, therefore, incorrect. In the same vein, option D is incorrect because the tan mice have different food requirements from the brown mice.
The only correct option is A.

hich two phrases in this passage point to the meaning of the word stealthily?
The question in her mind, and one not easily solved, now was, 'How can I get away?' So, as was her usual custom, she 'told God she was afraid to go in the night, and in the day every body would see her.' At length, the thought came to her that she could leave just before the day dawned, and get out of the neighborhood where she was known before the people were much astir. 'Yes,' she said, fervently, 'that's a good thought! Thank you, God, for that thought!' So, receiving it as coming direct from God, she acted upon it, and one fine morning, a little before day-break, she might have been seen stepping stealthily away from the rear of Master Dupont's house."

In eukaryotes, general transcription factors A) are required for the expression of specific protein-encoding genes. B) bind to other proteins or to a sequence element within the promoter called the TATA box. C) inhibit RNA polymerase binding to the promoter and begin transcribing. D) bind to sequences just after the start site of transcription.
Answer:
B
Explanation:
The general transcription factors bind to other proteins or to a sequence element within the promoter region known as the TATA box.
Transcription is a biological process involving the synthesis of RNA from a DNA template. The process of transcription begins with the binding of an enzyme, the RNA polymerase, to the promoter region of a gene. Prior to that, however, a group of enzymes known as the transcription factors must bind to a specific sequence within the promoter region - the TATA box. The binding of the RNA polymerase signals the unwinding of the section of the DNA to complete the initiation complex.
The correct option is, therefore, B.

Models can be used to obtain information about scientific processes and objects that may be difficult to study in real life. Which of the following scientific processes or objects would best be studied by using a model?
Answer: Formation of a solar system
Explanation:
The options include:
A. the effects of an antibiotic on a disease-causing bacterium
B. the formation of a solar system
C. the chemical composition of a protein
D. the growth pattern of a pea plant.
A model is simply used in the representation of real life cases or scenarios.
The scientific processes or objects that can best be studied by using a model would be the formation of a solar system.
Studying the solar system in real life can really be challenging and difficult, thereby it's better if studied through the use of a model.
In fruit flies, a dominant gene, G, codes for the trait of gray body color. A recessive gene, g. codes for black body color. Two fruit flies mate to
produce offspring
GG

Offspring
Which prediction about the offspring's body color is based on the properties of genetic reproduction?
O A The offspring can only express the trait of gray body color.
OB. The offspring can only have genes for the trait of gray body color.
O c The offspring can express either the gray or the black body color trait
O 0. The offspring are equally likely to have genes for the gray or black body color trait.
The prediction about the offspring's body color is based on the properties of genetic reproduction, it can only express the trait of gray body color. The correct option is A.
What is the dominant and recessive gene?Recessive and dominant genes. Dominant/recessive interactions are the most frequent type of allele-allele interaction. When one (dominant) allele of a gene effectively outweighs the other (recessive) allele, the allele is said to be dominant.
Blood types and eye color are two instances of dominant/recessive gene interactions. Due to recessive inheritance, the disease can only be brought on by a pair of faulty genes. Carriers are individuals who have only one faulty gene out of the pair.
Therefore, the correct option is A. The offspring can only express the trait of gray body color.
