Which best describes reproduction? Asexual reproduction may lead to an accumulation of mutations in the DNA. Sexual reproduction allows for diploid gametes to combine to increase genetic variation. Asexual reproduction leads to the formation of haploid gametes. Sexual reproduction allows for more gametes to be formed than asexual reproduction does.

The best and most correct answer among the choices provided by the question is the second choice. The statement "Sexual reproduction allows for diploid gametes to combine to increase genetic variation." best describes reproduction. I hope my answers has come to your help. God bless and have a nice day ahead!

Why do you think plasmids and bacterial cells are such important tools in genetic engineering?

Plasmids contain extra nucleoid genitic material. By virtue of plasmids bacteria have won their battle againt the miracle drugs like penicillin, streptromycin, asprin etc. Well genitic engineering retrieves their adapted and evolved tendencies to be applied for a long lasting cure.

Briefly describe the DNA transcription process, which involves the transfer of the DNA genetic code onto an mRNA molecule. Include in this answer the role of enzymes.

In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase 2 catalyzes the formation of a pre-RNA molecule, which is then processed to form a mature RNA. The resulting RNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.

Molecular biologists are using __________ to directly manipulate genes for practical purposes. A) DNA cloning B) DNA polymerization C) genetic engineering D) bacteriophage infestation (help plz)

Answer: C) genetic engineering  

Molecular biologists are using genetic engineering to directly manipulate genes for practical purposes. Genetic engineering is an artificial technique for manipulation of the genome of the organism which involves deletion or insertion of genes of interest. This artificial manipulation is done in order to remove mutant genes from the organisms genome to cure diseases and disorders,  new genes are introduced which can produce desirable traits.

What process most contributes to genetic variation in a population

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

This is the structure in the cell nucleus that houses a cell's genetic information. Example: Humans have 46 of these.

Answer: DNA molecules is packaged into chromosomes which are found in the cell nucleus.

Explanation: Chromosomes are made up of DNA (deoxyribonucleic acid) coiled around proteins called histones that support its structure. In humans cells there are 23 pairs of chromosomes, that makes a total of 46. Twenty-two of those pairs are autosomes while the 23rd pair is called sex chromosomes.

The genetic information is stored in the structure of the DNA, so this molecule is the hereditary material in almost all living organisms. That is why it contains the instructions to construct components of the cell.

- State the central dogma of molecular biology. - Outline research that determined that DNA is the genetic material. - What are Chargaff's rules?

DNA stands for deoxyribonucleic acid. The deoxy- in the DNA is a short term for deoxyribose. The nucleic acid molecule has three parts; sugar, phosphate and a base. The phosphate in the DNA acts as a backbone of the molecule. It is also responsible for the DNA’s ‘double-helix’ structure. The base has four codes namely adenine, thymine, cytosine and guanine. Adenine and thymine are bse pairs whereas cytosine and guanine are base pairs. They are not to be interchanged. Resulting in one cause mutation in the gene.

According to advocates for the use of genetic engineering, which is an example of the importance of recombinant DNA technology? Genes from nuts used in other organisms can affect allergies. The increase of patents drives the seed cost. There is a diminished opportunity for organic agriculture. There is a reduced use of pesticides, herbicides, and fertilizers.

Answer;

There is a reduced use of pesticides, herbicides, and fertilizers.

Explanation;

  • Recombinant DNA technology involves the process of joining DNA molecules from two different sources and inserting them into a host organism, to generate new genetic combinations that could be used by humans in various field such as medicine, agriculture, etc.
  • Recombinant DNA technology has a number of applications in medicine, health, agriculture and nutrition. For example in medicine it is used to create products such as human insulin.
  • Recombinant DNA technology has decreased the amounts of herbicides and insecticides used by farmers and also increased the production of crops.

Which describes an advantage of sexual reproduction? A. more offspring produced at a faster rate B. genetic variation C. offspring that are identical to parents D. rapid growth of gametes

Sexual reproduction results in more genetic variation. Due to small mutations that occur frequently from such, the gene pool is widened. For example, bird feather pigment differences are a result of genetic variation. As a result of this being advantageous, females of that species prefer those males with better color plumage, and thus passes on the gene to future generations.

Colorado has a vast population of lodgepole pines. A population of lodgepole pines have been killed in a section of the forest. What is a possible limiting factor of that population? devastation by the pine bark beetle Colorado’s long history of acidic soils genetic variability shallow root system

The correct answer is devastation by the pine bark beetle.  

The pine bark beetles are very common pests, which are found on the pine trees of the Colorado. These beetle feed on the bark of the pine trees, which result in the loss of nutrition and trees becomes dead. In the given case, the attack of the pine bark beetle can be the reason for death of the pine trees and limiting factor to the population.

How do mitosis and meiosis differ in the division of genetic composition?

Mitosis is the process in which the chromosome are separated into two identical sets of chromosomes which in the end have their own nucleus. Meiosis is the division in 1/2 and then in 1/2 again causing 4 sets of chromosomes. So, your answer would be mitosis produces two genetically identical daughter cells but meiosis produces four genetically different daughter cells.

What would happen if gametes were not haploid? a. The offspring would have half the number of chromosomes it is supposed to have. b. The offspring would have double the number of chromosomes it is supposed to have. c. The offspring would be genetically identical to it's parent. d. The offspring would be genetically different from it's parent.

If haploid didn't occur on gametes, it would occur on diploid, which would increase the number of chromosomes, and the child would have a lot of them.
So, what would happen if gametes were not haploid is that B. the offspring would have double the number of chromosomes it is supposed to have.

Which argument supports the idea that viruses are alive? A.Viruses have a cell membrane. B.Viruses contain unique genetic information.. C.Viruses replicate in a host. D.Viruses do not produce proteins.

The argument that supports the idea that viruses are alive is that B. viruses contain unique genetic information, just like humans do.
Having a cell membrane doesn't necessarily make the organism alive. Not producing proteins also doesn't mean that an organism is alive, because living things do produce protein. Viruses themselves don't replicate, they get into a host and command them to replicate with viruses inside.

Double helix structure of dna brca1 and brca2. BRCA1 expression is reduced or undetectable in the majority of high grade, ductal breast cancers. It has long been noted that loss of BRCA1 activity, either by germ-line mutations or by down-regulation of gene expression, leads to tumor formation in specific target tissues. In particular, decreased BRCA1 expression contributes to both sporadic and inherited breast tumor progression.
