What is a gene? HELP PLEASE
Answer:
Option A is correct
Explanation:
Gene is the basic unit of heredityGene is actually a sequence of nucleotides in the DNA.Termed by JohanssonPart of DNA having information for translationLinearly arranged on the chromosome.Present on a particular locus on the chromosome.Every person has 2 copies of each gene, one inherited from each parent.Does mutation decrease or increase genetic variation
Answer:
Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation

Decide if the following statements best describe map-based genome sequencing, best describe whole-genome shotgun sequencing, or apply equally to both sequencing methods.
a. starts with libraries of large, overlapping DNA fragments
b. starts cloning and sequencing of short, random DNA fragments
c. uses genetic recombination data to help arrange sequences correctly
d. requires sequences to be annotated after contig assembly
e. requires chromosome fragments to overlap for contig assembly
f. requires subcloning of large fragments into smaller clones for sequencing
g. is a better approach for repetitive sequences
1. Map-based genome sequencing
2. Whole-genome shotgun sequencing
3. Both sequencing methods
Answer:
1. Map-based genome sequencing: a; c; f; g
2. Whole-genome shotgun sequencing: b
3. Both sequencing methods: d; e
Explanation:
Map-based genome sequencing is a method that makes use of a reference genome sequence in order to determine the relative position of the DNA fragments before they are sequenced. This method is useful to determine the position of repetitive DNA fragments (for example, duplicated genes, repetitive non-coding regions, etc.) and Transposable Elements. Therefore, map-based genome sequencing is a suitable approach for large genomes (which are usually composed of repetitive sequences). On the other hand, in whole-genome shotgun sequencing, DNA sequences are obtained before the correct order of these DNA fragments is known. In this method, the genome is fragmented randomly into small DNA sequences (between 100 and 1000 base pairs), which are subsequently sequenced through the chain-termination sequencing approach (i.e., Sanger sequencing) and finally ordered by using bioinformatic tools that assemble overlapping reads.

What is glucagon's major role in the body?
Answer:prevent blood glucose levels dropping
Explanation:Glucagon's role in the body is to prevent blood glucose levels dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream. This process is called glycogenolysis.

if your answer is right you l get brainly
Answer:
Lupus refers to autoimmune disease in which the immune system of the body attacks its normal and healthy tissue instead of virus and bacteria. Symptoms of this disease include inflammation, swelling, and damage to the joints, skin, kidneys, heart, and lungs etc. The main cause of this disease is the environment that triggers Lupus. Chemotherapy and medications such as Nonsteroidal anti-inflammatory drugs and Antimalarial drugs etc are used for its treatment. Due to the disease's complex nature, it is often called "the of 1000 faces". In the united states there are about 16000 new cases of lupus every year. There are different kinds of lupus. This article will focus mainly on systemic lupus erythematosus (SLE), but other types include discoid, drug-induced, and neonatal lupus. Currently there is no cure for lupus, but the symptoms can be managed with care. The treatment aims to manage and prevent flare ups. The exact treatment will depend on how lupus affects the individual. Without treatment, flares can occur that may have life-threatening consequences.

While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hear them
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.

Which type of organism is it?
A. logistical
B. an r-strategist
C. a K-strategist
D. density dependent
THE ANSWER IS....
Answer:
B. an r-strategist
Explanation:
R-strategist (also known as r-selected species) refers to species whose population growth is based on the maximum reproductive capacity of the individuals under optimum environmental conditions (i.e., the biotic potential). These species are well known to produce numerous offspring and they show exponential population growth. The most common features of the R-selected species are 1-high reproductive rate, 2-rapid development, 3-early reproductive age, 4-small size, 5-short life spans, 6-poor competitive ability, and 7-high mortality. Some examples of r-selected species include rabbits, mice, marine invertebrates (e.g. jellyfish), weeds, bacteria, etc.

12. Individuals with Type O blood are able to produce both Anti-A and Anti-B antibodies, while individuals with Type AB blood produce neither of these antibodies. Explain why this is the case. How does this relate to the idea that people with Type AB blood are often referred to as universal recipients for transfusions
Answer: Blood group O individuals are able to produce Anti- A and Anti- B and are often referred to as UNIVERSAL DONORS, while blood group AB individuals produces none and are often referred to as UNIVERSAL RECIPIENTS
Explanation:
Two antigens, type A and type B, occur on the surfaces of the red blood cells in a large proportion of human beings. These antigens are referred to as agglutinogens because they often cause blood cell agglutination during blood transfusion. Because of the way these antigens are inherited, people may have neither of them on their cells , they may have one or they may have both simultaneously.
When type A antigen and type B antigen is not present in an individuals reb blood cell as seen in blood group O, antibodies known as Anti-A and Anti- B develops in the plasma. This is because small amounts of type A and type B antigens enter the body through food, bacteria and other ways and they initiate the development of anti A and Anti- B antibodies in their plasma.
Furthermore, individuals with blood type AB has antigen A and B on their red blood cells and therefore do not develop antibodies A and B in their plasma. This makes them universal recipient as their blood do not discriminate any ABO blood group during blood transfusion.
The __________ of a protein determines its ___________.
Answer:
Explanation:
The amino acid sequence completely determines the three-dimensional structure of a protein.
You are given a constitutive mutant, but you are not told whether it is constitutive due to a repressor mutation (i-) or an operator mutation (oc). Determine what could be added to the system that would allow you to determine the difference between the two mutants. You will add the same thing to each and indicate the results of the experiment.
Answer:
Explanation:
Repressor molecules, as we recognize them to be proteins occur as transcription factors that may function on their binding sites within the same genome or even on a different genome.
As a result, repressor molecules behave in a trans-active manner. Operator, on the other hand, acts as a binding site mostly on the chromosome genome which can only trigger downstream genes. As a result, Operators are cis-acting.
In this scenario, if we give the system a Plasmid containing a wild-type repressor gene, the repressor molecules would only attach to the usual Operator sites.
In the 1st scenario:
The Operator is regular and normal, but I- is mutated. As a consequence, the additional extra plasmid's normal repressor molecules will stick to the operator site, causing suppression or repressed expression.
In the 2nd scenario: genome
The repressor is natural, but Oc is mutated. As a consequence, the additional extra plasmid's normal repressor molecules would not adhere to the operator region, resulting in the same Constitutive expression.
