Answer:
C. Non-covalent interactions between the protein and specific bases in the major groove of DNA
Explanation:
Activator or repressor proteins are proteins with specific DNA-binding domains that have affinity by one or two DNA strands. In general, these proteins interact with the major groove of the B-DNA structure since this structure exposes more functional groups for binding. Non-covalent interactions are a type of interaction that does not involve the sharing of electrons. The interaction between proteins and DNA is due to the combination of different non-covalent interactions, which can be classified into four major types: van der Waals, hydrophobic, hydrogen and ionic interactions.
<u>Answer:</u>
<em>C. many more generations can be studied using short-lived organisms</em>
<u>Explanation:</u>
<em>Fruit flies are organisms with a shorter lifespan.</em> Their average lifecycle takes about a week to develop from lava to an adult. This <em>characteristic of fruit flies are reason they are used for the genetic investigation. </em>
The <em>genetic characteristics of the organism</em> can be studied over a short time. The accuracy of the study can be increased as there will be more <em>data and statistics related to same experiment. </em>
<em>Long term effect as well as short term effect can be studied easily. </em>
This mutation will cause the cheetah to not be able to run as far as a cheetah that does not have the mutation
Carrying capacity is the paramount number of a particular species that the earth or ecosystem can hold while limiting factors are the biotic and abiotic factors that confines or limits the growth of the living organism.
More the amount of limiting factor, greater will be the number of growth of the organism as the raw materials to hold life would be enough to sustain these many number of organism. Therefore, limiting factor governs the carrying capacity of various organisms on earth.
Answer:
False
