This is the DNA. I'm going to only use the upper strand to demonstrate what this strand would code for before and after a single bp deletion (so write it as mRNA). I will also write it how it's easier to see this which is to split them up into the 3 base codon system. Note that you don't need to know the amino acid code - you use a table to find these.
ORIGINAL (mRNA on top, Amino Acid (AA) on bottom:
5'-AGC GGG AUG AGC GCA UGU GGC GCA UAA CUG-3'
SER GLY MET SER ALA CYS GLY ALA STOP LEU
Note that the protein would stop being made at the stop codon and the LEU wouldn't matter at the end...
Now, I will remove one bp...(I bolded it up top). Rewrite the mRNA and find the corresponding AA...
NEW
5'-AGC GGG AUG GCG CAU GTG GCG CAU AAC UG-3'
SER GLY MET ALA HIS VAL ALA HIS ASN .....
Completely different amino acid sequence after the methionine (MET). The stop codon is gone...the protein would continue being translated until it reaches another stop codon...so not what was supposed to be made!
During gas exchange, the cell membrane of a single-celled organism has the same function as the respiratory system in humans. The respiratory system is a biological system which is composed of specific organs and structures such as nose, pharynx, larynx, trachea, bronchi and lungs that are used for gas exchange in humans. The primary function of the respiratory system is to transport oxygen into the body and to breathe out carbon dioxide, which is a waste product of cellular function
Answer:
Madge is likely to have schizophrenia.
Explanation:
Schizophrenia is a mental disorder that causes an individual to suffer delusions and hallucinations that cause totally abnormal and parranoic behaviors.
As has already been said, schizophrenia causes altered and abnormal behaviors, confused thoughts and difficulties in adapting to reality. It is a very disabling disease and can cause an individual to completely lose control of his mental faculties.
Madge's behavior shows that he has confused thoughts, paranoid behaviors and loss of reality, so we can say that he is likely to have schizophrenia.
First, we need to solve for the common ratio from the data given by using the equation.
a(n) = a(1) r^(n-1)
1024 = 4 r^(9-1)
256 = r^8
r = 256^(1/8)
r = 2
Then, we can find the sum by the expression:
S(n) = a(1) ( 1 - r^n) / 1-r
S(9) = 4 (1 - 2^9) / 1-2
S(9) = 2044
Therefore, the correct answer from the choices listed above is option B.
The growth of the population is described below.
<h3><u>Explanation</u>:</h3>
The population growth of the region is varying according to many factors like,
A. Members of the reproductive age group.
B. Availability of nutrition.
C. Mortality rate of the population.
Here the members of the reproductive age group are few. The population being small in a large area there is a high availability of nutrients.
So the growth rate of the population will be very high. This is called the log phase of the growth.
Then comes the lag phase of growth where the population is considerably big with a fight for food and shelter. The survival of the fittest is seen and the population still grows but slowly. This is the lag phase.
But with time, the population growth is stopped because the ecosystem has a particular carrying capacity which is the maximum number of population that the ecosystem can support. So beyond this, the population won't increase, and thereby the natality rate and the mortality rate becomes equal.
