Answer:

they are evolutionary neutral

Explanation:

Transposons are genetic mobile elements that move into the genome by means of cut-paste and copy-paste mechanisms. In consequence, transposons are known to produce mutations in the inserted genomic sequences.

Non-coding DNA regions have been generally assumed to be evolutionary neutral, it means that they might resist genetic polymorphisms (such as, for example, those caused by the insertion of transposon elements) and don't have direct effects on the phenotype of the organism. However, it is important to note that recent evidence supports the idea that noncoding sequences play important regulatory roles, thereby mutations in these genomic regions may have a deleterious effect on the organism.

Someone new is preparing media for lab and adds buffers to the EMB agar that raise the pH to 7.8. The starting pH of EMB plates

mestny [16]

Answer and Explanation:

Eosin Methylene blue agar or EMB agar consists of sucrose, lactose, methylene blue and Eosin Y. These segments make it a differential medium which permits development of gram-negative microorganisms. Gram positive microscopic organisms develop inadequately on this medium.

It is particular for development of gram-negative microscopic organisms. It likewise separates between non-fermenting gram negative enteric microscopic organisms and lactose fermenting.

Lactose fermenting gram negative microscopic organisms use lactose to deliver corrosive which changes the shading to dull purple. Some of the lactose fermenter will exhibit dim provinces with green metallic sheen while different settlements with purple focus. Green metallic sheen is because of creation of solid acids.

In the event that the beginning pH is 7.8 rather than 6.9-7.3, the color won't change shading regardless of creation of acids. Consequently, it won't be conceivable to separate between lactose fermenter and non-fermenters.

10. Which type of homeostatic mechanism is the most common in the human body?

natima [27]

Answer:

Explained below:

Explanation:

Type of homeostatic mechanism in the human body which is most common is the maintenance of body fluids, dilute and solutions of water that carry liquefied chemicals found in internal part of the cell and the surroundings of them. the internal part of the cells, it is named as intracellular fluid, the external part of the cells, it is named as extracellular fluid. All the materials such as oxygen, nutrients, proteins, and ions, are needed for survival.

How does the cell regulate the substrate specificity of ribonucleotide reductase to maintain equal amounts of all four deoxynucl

Kruka [31]

Answer:

The correct answer is A When dTTP is bound to the specificity site, more dCDP is produced

Explanation:

Ribonucleotide reductase catalyzes the conversion of ribonucleotide to deoxyribonucleotide.

When dTTP is bound to the specificity site at that time dCDP is produced.The So formed dCDP is converted to dUDP by the help of dCDP deaminase.The dUDP is then converted to dUTP by phosphorylation.

Finally the dUTP is converted to dTTP by the catalytic activity of thymidylate synthase with the presence of N5 N10 methylene tetrahydrofolate.

Thus equal amount of deoxyribonucleoside triphosphates are maitained by the cell.
