Question:

Is non-gene coding DNA considered junk DNA? Explain why or why not?

Nichole S.
Answer:

The non-gene coding portions of DNA are no longer considered junk DNA. Why? Because just because the DNA doesn`t code for a gene doesn`t mean it`s useless. We`ve discovered that many of the so-called junk portions of DNA code for mRNAs and snRNAs under the right conditions. These forms of RNA can catalyze certain processes just as if not more effectively than a gene which will make a protein can. If fact, it`s believe that mutations in these non-coding regions of DNA might result in some of our genetic diseases such as Type I Diabetes.

Question:

Which of the below sentences is correct: A) I rode in the train. B) I rode next to the train. C) I rode on the train. D)I rode in front of the train.

Nichole S.
Answer:

The correct answer is C. Why? Because trains are considered platforms. Trains have such a large floor space that the floor space is considered a platform instead of a container. Therefore, we have to use "on" for things with large amounts of floor space like ships, buses, and trains. However if the area has a small floor space, we use "in". Cars and hot air balloons have very small floor spaces, so we must use "in" since it`s classified as a container space not a platform.

Question:

Throughout the years, it`s been discovered that a more active, playful teaching style is better for student learning. A student learns best when their mind is relaxed. When the mind is relaxed by a more active style of teaching, a student is able to more effectively retain information. Please find the grammatical error in the sentences located above.

Nichole S.
Answer:

The answer is the "their" located after "A student..." in the second sentence. This "their" should actually be a he or she because the pronoun must agree with the singular "student" noun that it is referring to.
