Any time a scientific theory is challenged, it means it's not a good theory. And this statement is not valid. In theoretical models, they are revisited when there are further studies and discoveries found in a certain area where they can be remodeled and reintegrated instead of disregarding its credibility. Models, theories and paradigms are not challenged but rather encouraged, they are supported in many studies since these theories and models were created in order for us to understand a certain phenomenon but it would likely help the scientific society to be updated in the new forms or spheres of improvement rather than discouragement.

Cell growth occurs in interphase or mitosis?

Answers

Cell growth occurs in interphase.

The cell cycle is composed of interphase, mitosis, and cytokinesis. It can be described in five steps.

The first three steps of the cell cycle are called the interphase. This is where the cell grows, the cell matures, and where the cell carries out its life function. The fourth step is mitosis and the fifth step is cytokinesis.

The interphase has three stages. These are Gap 1, synthesis, and Gap 2.

Gap 1 or growth 1 - where the cell grows and functions normally. Cell growth is twice its original size.

Synthesis - where cell duplicates its DNA

Gap 2 or growth 2 - where cell resumes its growth in preparation for division.

What is the RNA sequence that will be formed from the DNA sequence: GGCTATTC?a. GGCUAUUC
b. CCGAUAAG
c. CCGUAUUG
d. CCGTUTTG

Answers

The correct answer is B.

According to base pairing rules, A will always pair with T and and G will always pair with C. This pairing happens in DNA.

When it comes to RNA, there is a slight difference. Thymine is never found in RNA but is replaced with Uracil. So instead of Adenine pairing with Thymine, it will be Uracil which takes the place of Thymine.

It is important to note that Thymine in DNA will code for Adenine in RNA because Adenine is found in RNA base sequence. However whenever Adenine in DNA wants to code for a complementary base to copy on RNA, then Adenine will call for Uracil, not Thymine.
