Answer:

A; test tube

Explanation:

In-vitro is defined as a technique of performing a given procedure in a controlled environment outside of a living organism. It does not correspond to the circumstances you would usually see in a living organism (since it is most likely in a test tube). This means that an in-vitro experiment could not be applied in a growth chamber in which outside/environmental factors affect the whole organism. You can also eliminate C since in vitro is exclusively taken place outside of a living organism. For D, you most likely wouldn't be able to observe much in a total vacuum as organisms work under regular Earth atmospheric conditions and a total vacuum would not accommodate that as it has a lower pressure.

How would a change to the sequence of nucleotides in a DNA segment affect the mRNA transcribed from the DNA?​
Mama L [17]

Answer:

It would change the nucleotide sequence of the transcribed mRNA

Explanation:

During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.

In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.

What kind of sequence or structure would you classify this as
jeka57 [31]

Answer:

The correct answer will be option-A.

Explanation:

Inverted repeats are the sequence of the nucleotide in a nucleic acid which is identical but arranged in the opposite orientation. The inverted repeat may be separated by some sequence or they may lie adjacent to each other. They can be read the same from the backwards or forward direction.

In the given question since four bases when read from the forward direction is same as reading the sequence from the backward direction like CGAC can be read the same both backward and forward.

Thus, option-A is the correct answer.

Which ties to the Calvin cycle because it gives photosynthesis a pathway of light reactions and dark reactions.
vovangra [49]

Answer:

What is the link between the light reactions and the Calvin cycle during photosynthesis?

Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2
