g In transcription, the 3'-hydroxyl group of the growing RNA strand: Group of answer choices NONE OF THESE binds to the 5' ribose. attacks the outermost phosphorous group of the incoming nucleotide. ALL OF THESE attacks the 5' hydrogen of the incoming nucleotide. interacts with a positively charged metal ion in the active site.
Answer:
attacks the outermost phosphorous group of the incoming nucleotide.
Explanation:
Transcription is the biological process where RNA is formed. As you may already know, RNA is an extremely important nucleic acid for genetic processes and the production of proteins. The transcription has three steps that are called start, elongation and end. In the elongation phase, the RNA strand is growing, at this time, RNA polymerase, which is the enzyme responsible for RNA elaboration, places the nucleotides, in the RNA strand, in the 5' - 3' direction. This enzyme causes the hydroxyl, which makes up the nucleotide at the 3' end of the forming RNA, to attack the phosphorus present in the incoming ribonucleotide.
Certain species of blind fish living in perpetual darkness in the ocean depths have evolved from ancestors that could see. Research indicates that the brain centers for vision in these fish is degenerating, whereas the brain centers controlling other senses are enlarging. What might be the MOST probable reason for the loss of vision in these fish
Answer:
Explanation:
Evolution for lack of light. If there is no reason for it you lose the ability but it strengthens other senses. It's compensation. The need to tell if the temperature has increased because of something nearby or ability to feel miniscule movement will increase to compensate for that lack of sense.

Explanation:
Both microscopy and motility agar are used to confirm microbial mobility. Research techniques involving microscopic determination of mobility and explain why both microscopy and motility agar are required to determine motility in some microbes.
Answer:
One allows microbe to move in the medium and the other allows to see it.
Explanation:
Both microscopy and motility agar are required to determine motility in some microbes because both substances helps to find out the mobility in the microbes. Motility agar is the medium that allows microbes to swim if they have flagella in their body while on the other hand, microscope is used to see the movement of microbes in motility agar. Microbes are small creature which can't be seen through naked eyes so we used microscope for it.

Explanation:
Which of the following is the most susceptible to damage by pollution in the air and
precipitation
A. The roots of trees
B. Trees at high elevations
C. Birds that migrate seasonally
D. Plants that grow in lakes or rivers
Answer:
B) Trees at high elevations
Explanation:
The atmospheric conditions and precipitation toxicity is most likely to affect trees at high elevations more so than the other answers.
The tree leaves, which are the main key to the tree's photosynthesis, absorb the oxygen and Co2 from the air, which are converted into nutrients. Without proper nutrients, the trees may die out.

An enzyme that breaks DNA, dispels the tension, and reseals the strand ahead of a DNA replication growing fork is called a(n):
Answer:
Topoisomerase
Explanation:
Topoisomerases are enzymes that produce changes in the topology of the DNA during replication, transcription, traduction, or reparation processes. They can cut one or both strands and in order to relieve torsional stresses in the supercoiled structure of DNA. With this, they help to maintain the chromosome's integrity. There are two types of topoisomerases: topoisomerase I (it cuts only one strand of DNA) and topoisomerase II (it is able to cut both strands of DNA).

The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable. Part of the cell membrane is a phospholipid bilayer, made of two layers of phospholipid molecules. However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates.
Explanation: So the correct answer is TRUE! don't forget to ate 5 stars and give brainlist!
The statement "the cell membrane consists of one layer of phospholipids" is absolutely false.
What is a Cell membrane?A Cell membrane may be defined as a type of biological membrane that significantly separates the interior components of the cells from the external environment. It also provides protection to the cell as well as other cell organelles.
A cell membrane is made up of a phospholipid bilayer. This illustrates that the two layers of phospholipid molecules are utilized in order to make an effective cell membrane.
It acts as selectively permeable in nature. The head or polar region of phospholipid is hydrophilic while the non-polar tail is hydrophobic in nature.
Therefore, the statement "the cell membrane consists of one layer of phospholipids" is absolutely false.

For the following question, match the key event of meiosis with the stages listed below. I. Prophase I V. Prophase II II. Metaphase I VI. Metaphase II III. Anaphase I VII. Anaphase II IV. Telophase I VIII. Telophase II Centromeres of sister chromatids disjoin and chromatids separate.
Answer:
VII. Anaphase II
Explanation:
During metaphase II, fibers of the spindle apparatus drive chromosomes to the cell equatorial plane, where they line up. Sister chromatids are holden together until they reach Anaphase II, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase II, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole

The enzyme dihydrofolate reductase (DHFR) normally resides in the cytosol, and it can be imported into mitochondria by appending a mitochondrial signal sequence. However, when this modified DHFR is incubated with methotrexate, which is a substrate analog that binds tightly to the active site, the modified DHFR is no longer imported. Propose an explanation for this finding.
Required:
a. Consider a transmembrane protein that spans the inner nuclear membrane. Suggest a pathway by which such a protein could reach its destination.
b. Clathrin can assemble with multiple types of adaptors to create coated vesicles. Explain why this multiplicity of adaptors is useful to the cell
Answer:
Within the mitochondria, the import takes place post-translationally. The imported protein must be in an unfolded condition so that it can go through the mitochondria's import machinery. In the existence of methotrexate, the bound DHFR moiety remains in the folded state, and thus, stays on the surface of mitochondria.
It is witnessed that the presequence must be of the length of 55 amino acids to cover both the membranes of mitochondria and must be of about sixty amino acids length to associate with the mhsp70. If the presequence of this methotrexate bound DHFR is of seventy-five amino acids in length, it can associate with mhsp70 within the matrix, to initiate the ATP reliant import within the mitochondria. Due to the presence of various endocytic and intracellular sorting signals, multiple adaptors are essential.
