How would gene expression be affected if there was an error in translation(reading instructions)?

1 answer:

5 0

Gene expression is about making mRNA which is then translated into a protein. If the mRNA that was expressed is mis-read it may or may not have an affect on gene expression. It will have a negative effect if:

1. The protein produced is required for gene expression (e.g. the DNA polymerase)

2. The protein produced is another critical protein that the cell cannot live without.

3. If the question is more about constantly misreading during translation, eventually the cell would die because the wrong proteins would be made (or not made at all).

Which of the following statements about bird respiration is FALSE?

zheka24 [161]

Answer:D

Explanation: The pulmonary air sacs of birds only permit a unidirectional flow of air through the lungs. Unidirectional flow means that air is inhale and exhale through one trachea alternatively. This means the bird lungs only receive largely fresh air which has a high oxygen content during inhalation and do not receive fresh during exhalation. While air flow bidirectional in mammals.

"In the snake experiment, what was the basis for the hypothesis that mimic species benefit from looking" like unrelated harmful

Fantom [35]

Answer:

The contrast in coloration was pivotal to determine if predators attack snakes based on their colors.

It was for studying MIMICRY in snakes.

Assuming all the.snakes were the same the number of attacks will not indicate anything about the effect of the colored rings.

This question on the need for provision of a controlled experiment during experimental investigation. Thus in order to test the effect of a particular condition,another contrasting condition must be provided to determine if the condition under investigation is the actual results obtaned or the influence of other factors in the environment or in the experiment.

The change in the color of the ring is the VARIABLE .In the artificial snake the variable is the presence of this coloed rings against its absence in this snake.

since it changes in the artificial snake

The term respiration describes the exchange of gases between your blood and the air. Cellular respiration ________.

kotegsom [21]

Answer:

The term describes cellular respiration

Explanation:

Cellular respiration, also known as internal or tissue respiration can be represented by the equation:

C6H12O6 + 6H2O ---> 6H2O + 6CO2 + Energy (in form of ATP)

From the equation, glucose from the blood is oxidized by oxygen trapped from the air by the nostrils. The main purpose of cellular respiration is to generate energy required by the body for various life activities
