How do eukaryotes replicate their genomes in a reasonable time frame, even though their DNA molecules are often considerably larger than those of bacteria?

Answers

Answer 1
Answer:

Answer: All chromosomes replicate once in a cell cycle

Explanation :

DNA replication is the action of DNA polymerases synthesizing a DNA strand that is complementary to the original strand or template strand.

In eukaryotes, it is during the S phase of the cell cycle that the vast majority of DNA synthesis occur and the entire genome uncoil and divide to form two daughter cells or copies while In Bacteria, replication begins at the origin of replication, supercoiled DNA is unwound by DNA gyrase, made single-stranded by helicase, and bound by single-stranded binding protein to maintain its single-stranded state.

In Eukaryotic DNA replication. all chromosomes replicate once in a cell cycle and Replication begins at many origins along each chromosome, this is why genome replication of eukaryotes occurs faster than those of bacteteria even thouge their DNA molecules are larger than the DNA molecules of Bacteria.

The milk sugar, lactose, is made up of glucose and galactose. What type of a carbohydrate is lactose?A.polysaccharide
B.monosaccharide
C.dissacharide

Answers

I think the correct answer from the choices listed above is option C. The milk sugar, lactose, is made up of glucose and galactose. Lactose is a dissacharide having two monosaccharide units. Hope this answers the question. Have a nice day.

The milk sugar, lactose, is made up of glucose and galactose it is a dissacharide.

Thus, A disaccharide is the sugar that results from the glycosidic connection of two monosaccharides, often known as a double sugar or biose.

Disaccharides are simple sugars that are soluble in water, just like monosaccharides. Maltose, lactose, and sucrose are three typical examples.

One of the four chemical classifications of carbohydrates (the others being monosaccharides, disaccharides, oligosaccharides, and polysaccharides) is disaccharides. Disaccharides having 12 carbon atoms, such as sucrose, lactose, and maltose, have the general formula C12H22O11.

Thus, The milk sugar, lactose, is made up of glucose and galactose it is a dissacharide.

The diagram below shows a helium atom.The particles labeled A are called (2 points)

A) Electrons

B) Protons

C) neutrons

D) nucleus

Answers

Particular A shown in the image is called protons, as option B shows.

What are Atoms?

  • It is the basic unit of matter.
  • It is a particle composed of electrons, protons, neutrons, nucleus and electrosphere.

An atom of any element is made up of a nucleus and an electron shell. In the electrosphere, there are small particles with a negative charge. These particles are called electrons.

In contrast, the nucleus has two types of particles, protons that have a positive charge and neutrons that have no charge.

Therefore, when we observe the image shown in the image above, we can see that there are particles with a positive sign, inside the nucleus of the atom. These particles are protons.
