How many primers are necessary for prokaryotic replication?

Biology

Zielflug [23.3K]3 years ago

As discussed in Chapter 3, DNA replication is a semiconservative process in which each parental strand serves as a template for the synthesis of a new complementary daughter strand. The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain. However, DNA replication is much more complex than a single enzymatic reaction. Other proteins are involved, and proofreading mechanisms are required to ensure that the accuracy of replication is compatible with the low frequency of errors that is needed for cell reproduction. Additional proteins and specific DNA sequences are also needed both to initiate replication and to copy the ends of eukaryotic chromosomes.

Why describes the basic structure of a fatty acid?
dalvyx [7]

A long carbon and hydrogen chain and a carboxyl group.

In images of fatty acids (the monomers of Lipids), it is depicted as a long carbon chain with hydrogen on the ends and connected to them as well, yet on the clear side is the carboxyl group.

Hope this helps!

the german physician robert koch provided evidence to support the germ theory of infectious disease. koch isolated bacteria from
densk [106]

He did this by experiment with anthrax. Using a microscope, Koch analysed the blood of cows that had failed of anthrax. He marked rod-shaped bacteria and supposed they caused anthrax.

<h3>What does anthrax do to a human?</h3>

Anthrax induces skin, lung, and bowel disease and can be fatal. Anthrax is analysed using bacterial cultures from infected tissues.

There are 04 kinds of anthrax: cutaneous, inhalation, gastrointestinal, and injection.

Anthrax is cured by antibiotics.

Thus,  He kept rod-shaped bacteria and supposed they caused anthrax.

1. Anaphase. In <span>Anaphase the sister chromatids separate from each other to the opposite sides of the cells.

2. </span>Chromosomes would not separate into two nuclei. <span>Mitosis is a process cell division, where one cell divides into two identical cells.
</span>
3. Metaphase I. <span>Meiosis prophase I is the phase in which chromosomal crossing over occurs. The phase after prophase I is metaphase I.

4. </span>Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes. <span>In the gametes, there are half of the number of chromosomes present in the body cell.

5. </span><span>A species has to adjust rapidly to a changing environment. To adjust to the environment, crossing over is necessary, and it does not occur in mitosis, but meiosis.

6. 50 percent. 
Parents:          Yy      x     yy
Offspring:    Yy    Yy    yy   yy
50 % is Yy  and 50% is yy.

7. </span><span>One parent had white eyes and the other was heterozygous for eye color. The ratio in the offspring is 50-50. The only possibility is the following:
Parents:       Rr     x     rr
Offspring   Rr    Rr   Rr   Rr

8. </span><span>Their fur will be a mixture of red and white hairs. The offspring will be heterozygous. They will have alleles for both red and white hairs and both will be expressed.
</span>
9. Not enough information.

10. <span>Both of the parents' genotype must have been Pp. The genotype of the white plant is pp since it is recessive:
Parents:        Pp     x     Pp
Offspring:   PP   Pp   Pp   pp
One of the four is white.</span>

thyroxine can trigger growth, temperature tolerance, or osmoregulation depending on the organism in which it is produced. which
larisa [96]

The primary hormone that the thyroid gland releases into the bloodstream is thyroxine. It is the inactive form, and organs like the liver and kidneys convert the majority of it into the active form triiodothyronine.

The body's metabolism, cardiac and digestive processes, muscle control, brain growth, and bone maintenance are all significantly regulated by thyroid hormones.

Hypothyroidism refers to the thyroid gland producing too little thyroxine. It could be brought on by autoimmune conditions, inadequate iodine consumption, or the use of specific medications. Sometimes there is no known cause. Untreated throxine before birth or during infancy can result in mental disability and stunted growth because thyroid hormones are crucial for both physical and mental development.

Adult hypothyroidism results in a slower metabolism. It may cause symptoms like weariness, a diminished ability to tolerate cold conditions, a low heart rate, weight gain, decreased appetite, impaired memory, sadness, muscle stiffness, and decreased fertility. For further details, read the article on hypothyroidism.
