Transcription is the process by which RNA is synthesis from DNA.
Transcription, as used in genomics, is the process of creating an RNA copy of a gene's DNA sequence. The information about the protein encoded by the gene is transported by this copy, known as messenger RNA (mRNA).
Although DNA is a more durable molecule than RNA, the latter is a more universal biological language.
During the DNA transcription process, which converts a DNA template into RNA, RNA polymerase enzymes produce an RNA copy of a DNA sequence. RNA polymerases are multi-chained polypeptides with a molecular weight of 500,000. In eukaryotic cells, there are three different categories of RNA polymerases.

Which of the following is least likely to produce recombinant chromosomes? A., crossovers between homologous chromosomes
Choice B., crossovers between non-sister chromatids
Choice C., crossovers between sister chromatids
B. crossovers between non-sister chromatids is least likely to produce recombinant chromosomes.
During meiosis, homologous chromosomes pair up and exchange genetic information through a process called recombination or crossing over. This process can happen between homologous chromosomes, as well as between sister chromatids, which are identical copies of a single chromosome.
A crossover between homologous chromosomes is most likely to produce recombinant chromosomes, as it leads to the exchange of genetic information between different chromosomes. This results in the creation of new combinations of genetic information, which can lead to genetic diversity.
A crossover between sister chromatids is also likely to produce recombinant chromosomes, as it leads to the exchange of genetic information within a single chromosome.

How can artificial selection decrease a population's biodiversity?a. it removes weaker species, leaving stronger species behind to reproduce. b. it selects which traits (good or bad) are passed onto the next generation. c. it increases the rate of natural selection and change within a population. d. it reverses natural selection by selecting species most adapted to survive.
By reducing the rate of natural selection and change within a population, artificial selection reduces population diversity.
Artificial selection happens when people choose individuals based on their desired qualities or personalities; this covers both plants and animals.
Natural selection takes place in nature; here, qualities that are inheritable and enable an individual's survival and reproduction, leading to an increase in population, are selected.
Natural selection can no longer take place when qualities and personalities are chosen for artificial selection. This also limits the number of genotypes because only those who are interested are advanced while others are not.
Natural selection promotes diversity by choosing individuals with the best genotypes for survival. As a result, artificial selection slows down natural selection and population change.

In the seventeenth century, francesco redi performed experiments using raw meat placed in jars. Half of the jars were covered, and half were left open. Redi noticed that the meat in the sealed jars did not have maggots, but the meat in the open jars did have maggots. Redi concluded that only flies could make more flies. Which part of the cell theory corresponds to redi's findings?.
The cell hypothesis includes a statement that says, "New cells come from the old cells," which is consistent with Francesco Redi's findings.
Francesco Redi's experiments in the 17th century provided the first substantial evidence disproving spontaneous generation by demonstrating that flies are required for the development of maggots on meat. He demonstrated biogenesis and refuted the hypothesis of spontaneous generation. He set up a straightforward experiment using two jars, both containing dead fish and meat, with the exception that one was kept totally closed and the other was left open. Redi went on to show that while live maggots or flies will reproduce when placed on decomposing flesh in a sealed jar, dead ones would not. This ruled out the existence of any necessary component in extinct organisms as well as the requirement of fresh air for the creation of life.

What is the main concept of natural selection?.
Natural selection is a straightforward method that results in long-term population changes in living things. It is actually so straightforward that it can be divided into five fundamental steps: variation, inheritance, selection, time, and adaptation. The co-discovereres of natural selection are Darwin and Wallace.
The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. Because of this variety, some people have characteristics that suit their surroundings more than others. In contrast to "artificial selection," which refers to practices like purposeful cross-breeding and selection for qualities that are appealing to people, "natural selection" refers to the process of choosing organisms with particular traits that is entirely motivated by nature.

What type of mutation is insertion?.
An insertion is the addition of one or more nucleotide base pairs to an existing DNA sequence (also known as an insertion mutation).
Due to the DNA polymerase sliding, this might frequently occur in microsatellite regions. A single base pair mistakenly inserted into a DNA sequence or an entire region of a chromosome can both be considered insertions. The smallest single base insertion mutation changes are thought to occur when the template and primer strands are base-paired separated, followed by non-neighbor base stacking, which can take place locally within the DNA polymerase active site. An insertion on a chromosome level denotes the addition of a longer sequence into a chromosome. Uneven crossover during meiosis is a factor that can cause this.
