The correct answer is "they allow traffic to proceed at the speed limit".
First of all, letter B is incorrect as the main function of the speed humps is not to bring harm to the motorists but to ensure the safety of the flow of the traffic. Letter A is correct as speed humps makes the motorists slow down on purpose for the traffic to proceed at a certain speed limit.
Answer:
Stephen is not his biological father.
Explanation:
DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.
The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.
Thus, the correct answer is option (a).
Answer:
peace be upon you dear
Explanation:
The sinus node signals the heart to speed up during exercise or in situations that are stressful, frightening or exciting. For example, a 10- to 15-minute brisk walk typically elevates the heart rate to 110 to 120 beats per minute
1. Two daughter cells will be produced. The cell division process known as mitosis (single cell cycle) always produces two identical daughter cells, irrespective of the number of chromosomes.
2. 72 chromosomes. As stated above, the daughter cells are identical to the parent cells and have the same amount of chromosomes.
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!
