Explanation:
Finn listed two of the three steps involved in gene therapy. 1. The normal allele is removed from the chromosome. 2. The normal allele is added to the cells of a person with the disorder. Which step should he also include, and where?
Answer:
The unhealthy gene sequence is cut from the DNA before 2
Explanation:
Gene therapy refers to genetic engineering techniques aimed at introducing exogenous nucleic acids (either DNA or RNA) into the patient's cells in order to restore gene function. Gene therapy techniques hold a great promise to treat genetic diseases and disorders. Gene therapy may involve replacing defective genes with a functional copy of the gene of interest within the desired cells. For this purpose, it is required to use a DNA-specific damaging agent to knock out the defective gene and subsequently restore normal gene function by inserting a functional gene sequence into the recipient cells. Gene therapy techniques can be divided regarding target cells into 1-somatic gene therapy, where genetic modifications are applied on somatic body cells (and therefore they are not inherited by offspring), and 2-germinal gene therapy, where genetic modifications are applied on germinal cells (i.e., gametes) or undifferentiated stem cells (and therefore genetic changes may pass to the following generations).
Answer:
The unhealthy gene sequence is cut from the DNA before 2

how can you add a normal one if one is still infected it would be pointless not to take it out
Transformation is a process in which bacteria take up new DNA released by dead cells and integrate it into their own genomes (see Chapter 9). In Streptococcus pneumoniae (which causes many cases of pneumonia, inner-ear infections, and meningitis), the ability to carry out transformation requires from 105 to 124 genes, collectively termed the com regulon. The com regulon is activated in response to a protein called competence-stimulating peptide (CSP), which is produced by the bacteria and exported into the surrounding medium. When enough CSP accumulates, it attaches to a receptor on the bacterial cell membrane, which then activates a regulator protein that stimulates the transcription of genes within the com regulon and sets in motion a series of reactions that ultimately result in transformation. Does the com regulon in S. pneumoniae exhibit positive or negative control
Answer:
Positive (inducible)
Explanation:
Increased levels of CSP induce the receptor to stimulate transcriptional activator functions, which allow gene expression to occur similar to what happens in positive inducible.
How can we stop the amount of emissions that contribute to greenhouse gases?
Which of the following describes a function of the endoplasmic reticulum within a cell?
intracellular transport
lipid synthesis
protein modification
DNA storage
Answer:
lipid synthesis
protein modification
intracellular transport
This is if you have to pick more than one
Explanation:
Because i got it wrong
The most important function of the endoplasmic reticulum is intracellular transport within the cell but ER also performs other functions.
What is intracellular transport?The Endoplasmic Reticulum transports nutrients from one part of the cell to the other within the cell.
What is Endoplasmic reticulum?The endoplasmic reticulum (ER) is a continuous membrane structure in eukaryotic cells that forms a series of flattened sacs inside the cytoplasm.
There are two forms of ER that are commonly found:-Rough ER, which has ribosomes embedded within its structure, giving it a rough appearanceSmooth ER, which lacks these ribosomes and hence appears smooth.The endoplasmic reticulum (ER) plays an essential role in protein synthesis, folding, modification, and intracellular transport.

How does anatomical homology provide evidence of evolution?
When scientists examine the gases ejected during a volcanic eruption, the majority of the gas is water vapor. How does the process of subduction provide a water source for volcanic gases?
Answer: Volcanic gases are gases given off by active (or, at times, by dormant) volcanoes. These include gases trapped in cavities (vesicles) in volcanic rocks, dissolved or dissociated gases in magma and lava, or gases emanating from lava, from volcanic craters or vents.
Answer:
When an oceanic crust and a continental crust converge, the denser oceanic crust subducts under the continental crust. During this process, seawater is added to the volcano’s magma. Much of this water is heated and ejected during an eruption as water vapor.
Explanation:
a red blood cell and plant root hair cell both have
Answer:
The job of both red blood cells and root hair cells is absorption. Red blood cells absorb oxygen through pulmonary veins and their capillaries in the lungs. Root hair cells, on the other hand, absorb water from the soil and transport them to adjoining cells for photosynthesis purposes.
Why can enzymes be used over and over again
Answer:
Enzymes are biological catalysts. They catalyse biochemical reactions. They increase the rate of reaction. They do not chemically react or get utilised in the reaction so enzymes can be used over and over again.

Parenchyma is a simple permanent tissue and xylem is a complex
permanent tissue.
Answer:
Explanation:
This is parenchyma is found below the epidermis of plants and It of living cells that have thin cell walls which are loosely packed to accommodate the intracellular space. Parenchyma consist of chlorophyll and they take part in photosynthesis.
Xylem is called a permanent tissue because it contain various types of cells like tracheids, vessels, xylem fibres, xylem parenchyma which is responsible for storing food.

The fisted answer is (B)
Patient 1 has Type ___ blood.
Answer:
A.
Explanation:
Patient 1 has Type A blood because agglutination occurs due to reaction with anti-B. We know that A blood group has antigen A and it is anti-B means that they attack on B type of blood cells while on the other hand, B blood group has antigen B and it is anti-A means that they will attack on the A type blood cells upon mixing. So according to the chart, there is nothing happens by reaction of the blood with anti-A whereas agglutination occur by reaction with anti-B so we can say that the patient has type A blood.

which two adaptations of herbivorous enables them to digest cellulose
Answer:
Cellulose Digestion in Herbivores
By means of the symbiotic gut bacteria, cellulose can be digested by herbivores with the help of monogastric digestion. Herbivores are less efficient than ruminants in the case of extracting energy from the digestion of cellulose. Here, cellulose is digested by microbial fermentation.
Explanation:
Their molar and premolar teeth help to crush and grind the food and bacteria present in their caecum help in the digestion of cellulose.
How does herbivorous digest cellulose?Cellulose is a polysaccharide made up of repeating glucose units linked by β-1,4-glycosidic bonds, only herbivores are able to digest this biomolecule.
Herbivores have molar and premolar teeth, this flat molars (back teeth) with rough surfaces, which are used for chewing up tough plant tissues. Ruminants have rumen having bacteria which are enabled animals to digest cellulose.
Inside the rumen of cattle, certain bacteria and protozoans are able to secrete the enzymes, which break the cellulose and convert it into glucose units to provide energy.
Therefore, teeth and bacteria two adaptations of herbivorous enable them to digest cellulose.
