Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome. If a researcher moves the repressor gene (lacI), along with its promoter, to a position at some several thousand base pairs away from its normal position, which of the following results would be expected?
A) The repressor will no longer bind to the operator.
B) The repressor will no longer bind to the inducer.
C) The lac operon will be expressed continuously.
D) The lac operon will function normally.
Answers
Answer:
D) The lac operon will function normally.
Explanation:
The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream. The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.so correct option is D) The lac operon will function normally.
If a researcher moved the repressor gene of lac I, along with its promoter; the lac operon will function normally. Option D is correct.
Promotor:
It is the genetic sequence that is recognized by the RNA polymerase to start the transcription.
Here, researcher moved the repressor gene of lac I , along with its promoter.
Therefore, transcription starts, it will express the repressor gene also because repressor gene was moved with promotor.

he most common source of osteomyelitis is an infection that migrates via the bloodstream. direct invasion from a fracture. surgical contamination. a joint prosthesis.
Answers
The correct answer is A. An infection that migrates via the bloodstream
Explanation:
Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.
In the box provided explain why living organisms contain more hydrogen atoms than any other atoms yet 65% of a typical organisms mass is oxygen
Answers
Answer:
The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.
Explanation:
This means that A orginasim will appear to contain more oxygen, but the size diffrence will mean that there will be more hydrogen, just of a smaller size with less mass, thus making up a lesser part of the organism in terms of mass, but the majority on the molecular level.
Answer:
Reason 1: The mass of Oxygen is 16 times that of Hydrogen. Hydrogen takes 16 atoms to equal the mass of 1 Oxygen atom.
Reason 2: A large portion of an organism’s mass is in the form of water. Water contains two hydrogen atoms and one oxygen atom.

If an experimenter wants to use the GFP method but needs to detect the presence or absence of several proteins at the same time, he can take advantage of mutational variants of GFP that emit what light?
Answers
Answer:
different colors
Explanation:
The green fluorescent protein (GFP) is a type of protein widely used in molecular biology laboratories because this protein can be used to detect the expression of proteins and to identify cellular structures. This protein displays green fluorescence when it is excited by blue light and, in the last years, many variants of the GFP protein have been developed. The altered GFP proteins react to distinct wavelengths of light, thereby emitting light to different colors. The mutants forms of the GFP protein are produced by genome engineering techniques that generate modifications capable of altering the folding of the normal GFP protein.

population of squirrels live together in forest an event occurred that caused the population to diverge into two different species over a long period of time which of the following is most likely the event occurred
Answers
A natural disaster.
Explanation:
A natural disaster would most likely have occurred to have the population of squirrels completely diverge from each other in order for them to become two separate species.
If a tornado, flood, earthquake, or another type of a natural disaster were to happen, it may have caused drastic damage to the ecosystem and environment of the squirrels. This would most likely cause the squirrels to split up, or diverge from each other and go to separate places in search of a new home.
Over time, these squirrels will reproduce with their own group. Each new group of squirrels, as they are both in different environments now, will have different adaptations from each other. This will eventually make it so they will never be able to reproduce with each other again if they were to meet, as they are now completely different species of squirrel.

A couple has just learned their neonate is diagnosed with osteogenesis imperfecta, and they
ask, "What caused our child to get this disease?" What should the health care provider teach
the couple about their neonate's condition?
Answers
Answer:
osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.
Explanation:
Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.
The disease 'osteogenesis imperfecta' is caused by the neonate inheriting it
from either of the parent because it's a genetic disorder. The health care
provider should teach the parent about how to prevent the effect of having
such disease such as bone fractures.
Osteogenesis imperfecta is a genetic disorder inherited by offspring from
their parent. The disease involves individuals having very brittle bones which are easily broken. The nurse should teach the parent to adopt bone strengthening steps such as adequate calcium intake and physiotherapy.

who invented biology
Answers
Answer:
The term biology in its modern sense appears to have been introduced independently by Thomas Beddoes (in 1799), Karl Friedrich Burdach (in 1800), Gottfried Reinhold Treviranus (Biologie oder Philosophie der lebenden Natur, 1802) and Jean-Baptiste Lamarck (Hydrogéologie, 1802).
Explanation:
When was biology invented?
Antiquity
The science of biology was invented by Aristotle (384–322 BC). Before Aristotle, many Greek philosophers had speculated about the origins of the Earth and of Life, but their theorizing was unsupported by empirical investigation.

The vector also contains other important elements. Explain their role:
5- AmpR:
6- ori:
Answers
Answer:
1. Lac P or the promoter is the binding site for RNA polymerase, situated just upstream to the gene.
2. Lac O or operator is a sequence situated just downstream to the sequence of the promoter at which binding of the repressor protein is done and ceases RNA polymerase enzyme from binding.
3. Lac Z refers to the gene that encodes for protein beta-galactosidase, which further results in the formation of glucose and galactose from lactose.
4. For high expression in E.coli IPTG is required. It attaches with the lac repressor and discharges the tetrameric repressor from the lac operator in an allosteric fashion, thus, permitting gene transcription in the lac operon.
5. AmpR is also known as the ampicillin-resistant gene, which is utilized as a selective marker for selection against ampicillin antibiotic.
6. Ori or the origin of replication refers to the sequence of the genome, which is accountable for the initiation of replication.

Answer:
The RNA interference (RNAi) mechanism
Explanation:
RNA interference (RNAi) is a biological process by which endogenous non-coding RNAs (ncRNAs) sequences target messenger RNAs in order to inhibit gene expression and translation. The regulatory ncRNAs bind by complementary base pairing to specific mRNAs and thus promote gene silencing by both posttranscriptional (mRNA degradation, block translation, etc) and by transcriptional (recruiting of histone/DNA modifying enzymes) pathways. The most common types of evolutionarily conserved ncRNAs found in plant and animal cells are 1-small interfering RNAs (siRNAs), 2-microRNAs (miRNAs), 3-piwi interacting RNAs (piRNAs, only present in animal cells) and 4-long noncoding RNAs (lncRNAs).
