The correct answer is: b. the removal of introns and alternative splicing of exons

Post-transcriptional regulation includes processes of regulation between transcription and translation such as RNA splicing, capping, addition of poly-A tail,  RNA editing.

RNA splicing represents the process of RNA processing in which newly synthesized pre-mRNA transcript is converted into a mature mRNA. This process occurs only in eukaryotic organism and includes the removal of introns and joining together the exons. RNA splicing might occur during or immediately after transcription and it is performed by spliceosome (complex of small nuclear ribonucleo proteins).

Alternative splicing is a regulated process in which a single gene can code for multiple proteins because particular exons of a gene may be included within or excluded from the final mRNA.

Anastasy [175]

The options are:

A) Right Frontal Lobe

B) Right Temporal Lobe

C) Left Frontal Lobe

D) Left Parietal Lobe

E) Hypothalamus

Answer:

The correct answer is D) Left Parietal Lobe

Explanation:

Parental lobe plays an important role in combining and interpreting sensory information coming from various body parts. It process information which allows individuals to know about the position of his body parts.

The damage in the left parietal lobe will affect the right side of the body and cause numbness and impaired sensation in the right side of the body. So the individual who has damaged left parietal lobe will not able to sense any stimulus in his right hand but can still move his fingers. So the right answer is D.

hodyreva [135]

Complete Question:

Part A: Identifying Variables

Read the following hypotheses and identify the variables.

If the number of cigarettes smoked increases, then the risk for lung cancer increases.

Independent variable: _______

Dependent variable: _______

If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.

Independent variable: _______

Dependent variable: _______

If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.

Independent variable: _______

Dependent variable: _______

Answer/Explanation:

Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.

Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.

In the above given hypotheses, the dependent and independent variables are shown below:

1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".

"Risk for lung cancer" => dependent variable

Number of cigarettes => independent variable

2. "number of shark attacks on humans" is dependent on "number of sharks swimming".

Dependent variable => number of shark attacks on humans

Independent variable => number of sharks swimming

3. Dependent variable => strength of bone

Independent variable => amount of milk a person drinks
