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.
A is false.
Respiration breaks down glucose and oxygen, not food.
Hope this helps.
Answer:
The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.
Explanation:
Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.
Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.
