Answer:
Point mutation is a change to a single nucleotide letter at a single point. Hence the name.
Chromosomal mutations are deletions, rearrangements or translocations a of large sections of DNA.
Both can have effects ranging from harmless to fatal/non viable.
A point mutation could be in a region that does not code protein (and thus likely harmless) or it could introduce an early stop to translation of a gene into a protein (which could be deadly)
Chromosomal rearrangements might have the breakpoints in non gene coding regions and so be harmless or the break points could interrupt the function of vital genes .

The figure above depicts the DNA-protein complex that is assembled at the transcriptional start site of gene X when the expression of gene X is activated in liver cells. Previous studies have shown th gene X is never expressed in nerve cells. Based on the diagram, which of the following most likely contributes to the specific expression pattern of gene X?
A.Expression of gene X produces large amounts of tRNA but undetectable amounts of mRNA.
B The general transcription factors inhibit the activation of gene X in liver cells by blocking the activator from binding to RNA polymerase II.
С The activator is a sequence-specific DNA-binding protein that is present in some tissues but not in other tissues.
D The enhancer is a unique DNA segment that is added to the nuclear DNA of some cells of an organism during the process of mitotic cell division but not other cells.
Answer:
C
Explanation:
The activator is a sequence-specific DNA-binding protein that is present in some tissues but not in other tissues. The correct option is C.
What is gene expression?Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
Because a particular protein can only be made when its gene is turned on, gene expression is significant.
However, there are several steps involved in translating a gene into a protein, and one of these steps—the creation of proteins—is crucial in the gene expression pathway that can be changed in cancer.
According to the diagram, the activator is a DNA-binding protein that only binds to certain sequences in select tissues.
Thus, the correct option is C.

Use the image below to explain protein synthesis and the steps of transcription and translation. Hint: Use the numbers 3-11 to guide your explanation.
Answer:
Protein synthesis is the process in which cells make proteins.It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. After a polypeptide chain is synthesized, it may undergo additional processing to form the finished protein.

Carbon ______________ are processes that add carbon to the atmosphere. Carbon ______________ are processes that absorb carbon
Answer:
Carbon sources
Carbon sequestration
Explanation:
Carbon sources are regions that produces atmospheric carbon dioxide. This carbon dioxide is naturally added to the atmosphere when organisms respire, decompose, rocks with carbonate are weathered and volcanoes erupt.
Carbon sequestration is the process of taken and storing atmospheric carbon dioxide. The method helps in reducing the amount of carbon dioxide in the atmosphere which in turn reduces global climate change.

Q. What are the different ways in which glucose is oxidised to provide energy in the various organism ?
Q. How is oxygen and carbon dioxide transported in human beings ?
Answer:
Hey mate......
Explanation:
This is ur answer.....
1A) There are 2 ways:-
• Anaerobic Respiration.
The anaerobic respiration process takes place in the absence of oxygen.
• Aerobic Respiration.
In aerobic respiration, breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water.
2A) Oxygen is transported from lungs to body cells in the form of oxyhemoglobin . the main 2 gases exchanged are 02 & C02 . 02 is absorbed by blood capillaries from lungs alveoli by diffusion while C02 is absorbed by blood alveoli from blood capillaries by diffusion.

how is making stuff with mud is science?? someone plss helpp plss
Answer:
Making stuff with mud is science because these are experiments used to establish facts and principles about mud and/or the different types of soil constituting the mud
Explanation:
Science is a discipline that studies the establishment of facts, principles and methods through experimentation and instills processes of investigations to learners. Making stuff with mud can be used to establish facts and principles e.g clay soil has smooth and fine particles and has high adhesive forces of attraction with water and hence will make longer and thinner ribbons while sand has large rough particles which make large and chubby (I couldn't think of another word) ribbons due to the weak adhesive forces between the particles and water.

students are modeling mRNA during the process of protein synthesis. which answer choice correctly describes the model of mRNA strand being transcribed
Answer:
This question lacks options, the options are:
A. the mRNA strand is complementary to the DNA template strand; however, uracil instead of adenine is paired with thymine
B. the mRNA strand is complementary to the DNA template strand; however, uracil instead of thymine is paired with adenine
C. the mRNA strand is an exact copy of the DNA template strand; however uracil instead of adenine is paired with thymine
D. the mRNA strand is an exact copy of the DNA template strand; however, uracil instead of thymine is paired with adenine
The answer is B
Explanation:
Protein synthesis which encompasses how gene is used to synthesize proteins consists of two processes namely; transcription and translation.
- Transcription is the process whereby the sequence of a DNA template is used to synthesize a mRNA strand. The mRNA sequence is synthesized using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine base (A) will always hydrogen pair with Thymine (T) while Guanine (G) will always pair with Cytosine (C).
This means that the mRNA strand produced is complementary to the DNA template strand that was transcribed. However, Uracil base (U) replaces thymine (T) in the mRNA molecule because Thymine is not found in RNA. Hence, Uracil instead of Thymine pairs with Adenine in the mRNA.
That is;
A - U, T - A, G - C.

Answers: examples of host defence mechanism include: Innate anatomical and physiological barriers, Innate cellular and chemical defenses.
Explanation:
The capability of the human body to resist almost all types of organisms or toxins that tend to damage the tissues and organs is known as IMMUNITY. This host defence mechanism can be classified into INNATE or adaptive immunity.
The immunity that results from general processes, rather than from processes directed at specific disease organisms is called the INNATE IMMUNITY. The anatomical and physiological barriers of the innate immunity provides the first line of defence against pathogens. Examples of these barriers of the innate immunity includes:
--> Destruction of swallowed organisms by the low stomach pH and digestive enzymes
--> The vigorous mucociliary clearance mechanisms of the respiratory airways and lungs.
--> Resistance of the skin to invasion by organisms
While examples of innate cellular and chemical defenses include:
--> Phagocytosis of bacteria and other invaders by white blood cells and cells of the tissue macrophage System
--> lysozymes, a mucolytic polysaccharide that attacks bacteria and cause them to dissolute.
--> basic polypeptides which react and inactivate certain types of gram- positive bacteria
-->natural killer lymphocytes that can recognize and destroy foreign and tumor cells.
