4)RNA polymerase binds to the promoter region of a gene and initiates transcription

Answers

Answer:

The correct order is:

4, 2, 1, 3

Explanation:

The list of options in this question depicts gene expression which involves transcription and translation processes.

Option 4 is simply describing the initial step of transcription where the enzyme RNA polymerase binds to the promoter region of a gene on the DNA and signals the initiation of transcription. RNA polymerase synthesizes a complementary strand of mRNA using the DNA it binds to as template.

Option 2 is a post-transcriptional process called SPLICING, which is the removal of the non-coding regions of a gene called INTRONS by enzymes called SPLICEOSOMES. This occurs in eukaryotic cell before the mRNA leaves the nucleus for the cytoplasm where translation will take place.

Option 1 signals the commencement of translation where a complex of ribosomal RNA and other proteins called RIBOSOME attaches to the mRNA molecule and uses the anticodons present in the tRNA to read the mRNA codons in order to carry the corresponding amino acid to the ribosome. The anticodons of the tRNA are complementary to the mRNA codon. At the end of translation, an amino acid sequence called polypeptide (future protein) will be released.

Option 3 tells us what happens after the translation process. The amino acids in the newly released protein are arranged in such a way that they make the protein a primary structure. The amino acids undergo certain modifications like folding that changesges the protein's structure from primary to tertiary.

Answer: 4213

The entire process is protein synthesis for gene expression.

The process  of  transcription  begins when the encoded protein information  from the DNA is transferred to the  mRNA.It begins when enzyme RNA polymerase bind with promoter region ( the point where the process of transcription begins) of a gene and initiates transcription.,the point where the process of transcription begins. The DNA double helix unwinds, the mRNA align and complementary paring of the bases occurs.

This is followed with the removal of noncoding part(introns) of the mRNA transcripts prior to translation  where;The spliceosome removes introns. This is essential because only the encoded part which contain the needed protein to be  transcribed is selected.

The mRNA is released, and leave the nucleus through the nuclear pore to the cytoplasm.In the cytoplasm the ribosomes with its two sub-units large and small  serve as templates for the mRNA with its anti codons and pairing  with the tRNA codons  in a complementary pairing for translation of amino acids to polypeptide sequence.

In the process of translation polypeptide chains of amino acids are formed as the complimentary  bases paired up to synthesize protein. Different levels of proteins are formed as the primary structure of the polypeptide chain undergoes hierarchical foldings to form the tertiary structure.

Explanation:

The first stage of cellular respiration glycolysis is an anaerobic process. During glycolysis glucose is converted to two molecules of pyruvic acid. How is glycolysis kept functioning in cellular respiration?

Answers

Answer:

Oxidation of NADH by electron transport chain ensures a continuous supply of NAD+ for glycolysis.  

Explanation:

To continue the process of glycolysis, cells must have a continuous supply of NAD+ which is required during one of the reactions of the payoff phase of glycolysis. Two molecules of NADH are formed per glucose molecule during glycolysis. The NADH gives its electrons to the terminal electron acceptors (O2) via electron transport chain. This ensures that the process of glycolysis is continued in cells to breakdown the glucose into pyruvate.

Final answer:

Glycolysis is the first step in the breakdown of glucose in cellular respiration, providing energy to the cell. It is an anaerobic process that takes place in the cytoplasm. Glycolysis generates two molecules of pyruvate, two ATP, and two NADH molecules.

Explanation:

Glycolysis is the first pathway used in the breakdown of glucose to extract energy in cellular respiration. It is an anaerobic process that takes place in the cytoplasm of both prokaryotic and eukaryotic cells. Glycolysis starts with glucose and ends with two molecules of pyruvate, generating a net gain of two ATP and two NADH molecules.

If oxygen is available, the pyruvate molecules can be further processed through aerobic respiration in the mitochondria. If oxygen is not available, fermentation can occur to convert pyruvate into other substances. Glycolysis is essential for providing energy to the cell, especially in situations where oxygen is limited.

B) The types of organisms living in the soil

C) The altitude of the location of soil formation

D) The amount of time it takes to create the soil

Answers

Answer:

A.

Explanation:

The factors that affect soil formation are climate, rock type, slope, time, and biological activity. Differences in these factors will produce different types of soil. Soil type determines what can grow in a region. Humus, the decayed remains of living organisms, is essential for soils to be fertile.

The type of rock and minerals in the parent material determine the type of soil created. So the correct option is A.

What is the process of soil formation?

The soil is a very essential one of our natural resources. Soil is important for the growth of vegetation that we depend on for food. It provides the plants with stability and nutrition. Soil is also a habitat for many microorganisms. It is also important for earthworms, rats, and a lot of other subterranean species that are present on earth.

Parent material is the material from which soil is formed. The source of all soil minerals is the rocks. The parent material is weathered chemically or physically. It is then transported and then deposited for the formation of the layers of soil. The parent material is usually the bedrock. Soil can also get transported because of natural factors like wind and water.

Pedogenesis is the name of the process for the formation of soil. It is first initiated by the weathering of rocks. The variations are developed according to the weather conditions.

Therefore, the correct option is A.

At 5 pm, there were 20 bacterial cells in a test tube. Knowing that the generation time is 6 minutes, how many bacteria do you expect there will be in the test tube at 5:30 pm? Bacteria reproduce by binary fission, in which one bacterium becomes two bacteria.

Answers

The question is incomplete as it does not have the options which are:

120 Cells 640 Cells 1280 Cells 56 Cells.

Answer:

640 Cells

Explanation:

The bacterial cell divides by the process of binary fission which divides a parent bacterial cell into two daughter cells.

In the given condition, the generation time or the average time between the two generations is 6 minutes. When he analyzed the population at 5 pm, he found 20 bacterial cells.

At 5.30 pm, the bacterial cell will have 640 cells as

1. After every 6 minute the population doubles

2. The minute's difference between 5 pm to 5.30 pm is 30 minutes.

3. Since 1 generation time-6 min therefore 30 minutes will have = 30/ 6 = 5 generation.

4. The bacterial cell will be calculated using formula

[tex]2^{number of generations}[/tex] x an initial number of bacteria in a population, therefore, [tex]2^{5}[/tex] x 20 = 640 bacterial cells.

Thus, 640 Cells is the correct answer.

Answers

Answer:

Option D, stimulating bladder contractions.

Explanation:

Neostigmine has a amine structure due to which it can cross the blood brain but once it gets absorbed it is secreted rapidly.

Disabled Urinary retention is a scenario in which the bladder never gets full.  Neostigmine leads to accumulation of acetylcholine which triggers concentration based contractions in the urinary bladder. The muscarinic receptor on the urinary bladder contracts the bladder and the contraction gets stronger with passage of time

Hence, option D is correct
