Answer:
d. AAU CCG CAU UGG A
Explanation:
A mutation is any change or alteration to the sequence of a gene. There are, however, different types of mutation depending on how it occurs in the gene. One of these types is INSERTION MUTATION as mentioned in this question. Insertion mutation is a type of mutation in which one or more nucleotide base is added to the sequence, hence, changing the reading frame of the original sequence.
In this question, the original mRNA sequence is given as: AAU CCG CAU GGA.
An insertion mutation will cause nucleotide base(s) to be added to this sequence, which will be noticed by an increase in number of bases in the sequence.
The correct answer is: AAU CCG CAU UGG A. In this mutated sequence, nucleotide "U" has been added to the sequence.
Answer:
Explanation:
The aim of the Hershey and Chase experiment was to show that DNA and not proteins are the genetic material.
Proteins are made up of amino acids which also has a nitrogenous base. Since the whole point of the experiment was to differentiate between the two i.e. show which one is the genetic material, it would be impossible to differentiate between DNA and proteins if the nitrogenous base was labelled.
Answer:
Secondary succession, type of ecological succession the evolution of a biological community's ecological structure in which plants and animals recolonize a habitat after a major disturbance—such as a devastating flood, wildfire, landslide, lava flow, or human activity

<span>To have the disease, males need only one copy of the affected X.</span>
So, the frequency of affected males will be the frequency
of the disease allele = 0.02
Females must inherit two copies and be
homozygotes, so the frequency of affected females will be the double of frequency
of the disease allele = (0.02)
Since the ratio between female and male is 50:50
that is half of the population is male and half female
<span>Then the overall frequency of the disease will be,</span>
(0.5) (0.02) + (0.5) (0.0004) = 0.01 + 0.0002
<span>Thus, the frequency of affected
individuals in this population is <span>0.0102.</span></span>
