How does semi-conservative replication help prevent mutations during DNA replications?

Answers

DNA replication is the process by which two DNA molecules are produced from one parent DNA molecule. DNA replication is semi conservative, this implies that, each strand in the double helix DNA molecule act as a template for the synthesis of a new, complimentary DNA strand. Because semi conservative method has a DNA template that is already accurately formed, the probability of having errors in the newly formed strand is drastically reduced.

Semi-conservative replication is a process of DNA replication in which each new DNA molecule formed contains one original strand (parental strand) and one newly synthesized complementary strand.

This type of replication occurs during the cell division cycle, ensuring that the genetic information is faithfully copied and passed on to the daughter cells without introducing significant mutations.

By combining accurate base pairing, proofreading, and repair mechanisms, semi-conservative replication ensures that the newly synthesized DNA strands are as identical as possible to the original parental strands. This fidelity in replication is vital for preserving the genetic information and preventing mutations that could lead to genetic disorders, cancer, or other harmful consequences in the offspring cells.

What was Fredrick miescher contribution to the discovery of the genetic code

Answers

Answer:

He discovered the cell nucleus and realized that inside the nucleus there was an unknown chemical substance. That substance was DNA.

Explanation:

Who discovered the DNA was Friedrich Miescher, a Swiss biochemist with great talent. Miescher, using substance precipitation techniques, such as pH changes in the medium, was able to discover and isolate the cell nucleus. Inside the nucleus he was able to isolate a previously unknown substance. It was the nucleic acid, DNA, which, at the moment, with the technology available until then, presented itself only as a white, flocculent precipitate, which Miescher would later call nuclein.

In 1869, Friedrich Miescher isolated "nuclein," DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA.

To sum it up the answer is yes.

Describe the genetic makeup of the offspring of asexual reproduction

Answers

There are two major types of reproduction in living organisms, these are sexual and asexual reproduction. Asexual reproduction is a type of reproduction in which an offspring is derived from a single parent. The offspring derived from the parent inherit DNA molecule from its parent, thus, the genetic information in both the parent and the offspring are identical. Thus, in asexual reproduction, the parent and the offspring possess identical genetic make up.

The offspring will have the exact same genetic makeup as the parent.

How was the brushtail possum transported to its new ecosystem?

Answers

The common brushtail possum was introduced to New Zealand in 1837 to establish a fur industry, but in the mild subtropical climate of New Zealand, and with few to no natural predators, it thrived to the extent that it became a major agricultural and conservation pest.

2.Patsy is studying different kinds of weathering. She has four pans full of dried modeling clay. Some she adds water to. Some she freezes overnight, then lets thaw, as summarized in the table below: PanAdded Water?Froze the pan?1yesyes2yesno3noyes4nono Then she compares the clay in all four of her pans. The clay in pan #4 was the same at the end of the experiment as it has been at the beginning. The clay in pan #1 had changed and broken up more than the others. Which of the following conclusions could Patsy have made? Frozen clay takes up more space than thawed clay does. Adding water to clay and then freezing it breaks the clay apart more than either freezing it or adding water to it alone. Adding water to clay and then freezing it helps plants to grow in the clay more than either freezing it or adding water to it alone. Wet clay takes up more space than dry clay does.
