In sexual reproduction, offspring are genetically different from their parents. This is because of the crossing over in meiosis.

Further Explanation:

All the living things reproduce through a process referred to as reproduction. The process of reproduction can occur in two types:

  • Asexual reproduction
  • Sexual reproduction

The asexual reproduction is a major type of reproduction in single-cell organisms like bacteria, Protista and archaea. Some fungi and plants also reproduce sexually. In this process, the offspring is produced from one parent and also pass the genetic information from one parent. The offspring is exact copy of parent because there is no genetic variation.

Sexual reproduction is the major method of reproduction in a variety of microscopic organisms. It almost includes all the plants and animals. The main process in sexual reproduction is:

  • meiosis
  • fertilization

Fertilization is a process of the fusion of gametes which are sperm and egg results in the diploid zygote. In meiosis ploidy level of germ cell get halved. Meiosis involves crossing over in between the non-sister chromatid of the homologous chromosome thus leads to genetic variation. So, the parents and offspring are genetically variable from one another.

How do dogs and birds both use DNA as instructions for building their bodies even though they are very different organisms
Hitman42 [59]

Answer:

Both birds and dogs use DNA as instructions for building their bodies even though they are very different organisms because DNA of all the organism are made up of same four type of base adenine, thymine, cytosine, and guanine. These bases make genetic code that is universal in all the organisms.

What is the difference between metaphase in mitosis and metaphase II in meiosis? How are they the same?
lora16 [44]

Answer:

What is the difference between Metaphase 1 and Metaphase 2? In Metaphase I, the 'pairs of chromosomes' are arranged on the Metaphase plate while, in the Metaphase II, the 'chromosomes' are arranged on the metaphase plate. In Metaphase I, the spindle fibers get attached to two centromeres of each homologous chromosome.

In metaphase 1 the pairs of chromosomes referred to as bivalents are totally condensed. Moreover the in metaphase 1 of meiosis there is no centromere division whereas in metaphase of mitosis it does. They align on the metaphase plate in between the poles.

DNA Polymerase helps copy a DNA molecule during the process of what?
PtichkaEL [24]
The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule. During this process, DNA polymerase “reads” the existing DNA strands to create two new strands that match the existing ones.

Every time a cell divides, DNA polymerase is required to help duplicate the cell’s DNA, so that a copy of the original DNA molecule can be passed to each of the daughter cells. In this way, genetic information is transmitted from generation to generation.

Before replication can take place, an enzyme called helicase unwinds the DNA molecule from its tightly woven form. This opens up or “unzips” the double stranded DNA to give two single strands of DNA that can be used as templates for replication.

DNA polymerase adds new free nucleotides to the 3’ end of the newly-forming strand, elongating it in a 5’ to 3’ direction. However, DNA polymerase cannot begin the formation of this new chain on its own and can only add nucleotides to a pre-existing 3'-OH group. A primer is therefore needed, at which nucleotides can be added. Primers are usually composed of RNA and DNA bases and the first two bases are always RNA. These primers are made by another enzyme called primase.

Although the function of DNA polymerase is highly accurate, a mistake is made for about one in every billion base pairs copied. The DNA is therefore “proofread” by DNA polymerase after it has been copied so that misplaced base pairs can be corrected. This preserves the integrity of the original DNA strand that is passed onto the daughter cells.

Structure of DNA polymerase

The structure of DNA polymerase is highly conserved, meaning their catalytic subunits vary very little from one species to another, irrespective of how their domains are structured. This highly conserved structure usually indicates that the cellular functions they perform are crucial and irreplaceable and therefore require rigid maintenance to ensure their evolutionary advantage.
