When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. ... This model for replication suggests that the two strands of the double helix separate during replication, and each strand serves as a template from which the new complementary strand is copied

Answer:

To synthesise new DNA and RNA

Explanation:During replication, DNA strands are separated from each other by helicase enzyme. These two separated strands act as a template strand. From the template, new DNA strands synthesised in opposite directions. The one strand synthesized continuously, called the leading strand and the other strand synthesized small fragments of DNA. This is a discontinuous process and the strand call lagging strand. The smaller fragments of DNA are called Okazaki fragments. The DNA polymerase adds new nucleotides and it is initiated by RNA primase in the template strands. This RNA primase later separates from the lagging strand and forms mRNA which comes to the cytoplasm from the nucleus. In this way, the original DNA strands form new DNA strands and the RNA.

How did the invention of the microscope contribute to knowledge about 1p living things?

natita [175]

Answer:

It made it possible for people to discover and learn about cells.

Explanation:

The cell is the basic unit of structure and function of all living beings. A cell can also be defined as a morphological, functional, and reproductive unit of all living beings.

Every living organism is made up of one or more cells. All cells are created from an existing cell. A cell is the smallest unit that has all the characteristics of life. A set of cells of similar or the same appearance, embryonic origin, and function is called tissue.

The science that studies the cell is called cytology. There are organic and inorganic compounds in the cell. Of the inorganic compounds, water and salts are the most common. Organic compounds in the cell contain carbohydrates, fats, and proteins.

Two species of meadowlarks have different mating calls that lead to reproductive isolation. What type of isolation does this exa

77julia77 [94]

Hi there!

The example of the meadowlarks is an example of behavioral isolation. This is because the mating call is a behavior the birds exhibit. This helps the birds to find their correct mate because though the birds look similar, they are not able to produce offspring.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Temka [501]

Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.

We can arrive at this answer because:

Despite having exons, prokaryotes do not have introns in their genomes.
This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.

This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.
