Aportion of a wild type (normal) mrna sequence reads gug acu uuu ccu ccc aua uga. a mutation occurred in the dna coding for the 4th codon from the left, and the mrna sequence now reads gug acu uuu acu ccc aua uga. what type of mutation has occurred?

The correct answer is Substitution point mutation.

Mutation is the permanent change in the genetic material of the organism. Point mutation means there is change in one nucleotide sequence and substitution mutation means replacement of one or more bases by the same number.

As per the question, mutation has occurred in the DNA coding for the fourth codon ( which is ccu in the mRNA sequence).

The fourth codon is changed from ccu to acu. This indicates that there is change in one nucleotide that is from c ( cytosine) to a ( adenine) and also it is a substitution mutation as cytosine is replaced by adenine.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.
