can someone plzz help me on this its hard:( ill give brainliest

Explanation:

New strands of DNA are lengthened by adding new nucleotides at the replication fork.

These methods primarily involve DNA synthesis techniques, such as polymerase chain reaction (PCR) and DNA sequencing methods. However, it's important to note that scientific advancements may have occurred since my knowledge cutoff, and there could be new techniques or technologies available.

PCR is a widely used technique that allows for the amplification of specific DNA sequences. It involves a series of heating and cooling cycles, which enable the DNA to denature (separate into single strands) and then be replicated using a DNA polymerase enzyme. By repeating this process, multiple copies of the DNA sequence of interest can be generated.

DNA synthesis involves the chemical synthesis of custom DNA sequences in the laboratory. This process typically employs a method called phosphoramidite chemistry. It starts with a DNA template strand and adds nucleotides one by one, using chemical reactions to build the new DNA strand. This method allows for the controlled synthesis of long DNA strands with specific sequences.

Modern DNA sequencing technologies, such as next-generation sequencing (NGS), can indirectly contribute to DNA lengthening. During the sequencing process, DNA strands are often amplified and replicated to generate sufficient material for analysis. This amplification step can result in the lengthening of DNA strands.

Answer:

Here ya go

Explanation:

The lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. In some interactions between lysogenic phages and bacteria, the lysogenic conversion may occur, which can also be called phage conversion.

Explanation:

the only possibilities for the childrens genotypes are; A and AB, so the fact that the child has a blood type of O isn't possible

The genotypes of Mrs. Smith and Mr. Smith are AO and BO, respectively. Therefore, the blood group of the offspring will be A, B, AB, and O.

Genotype is the genetic makeup of an organism. Genotype refers to the alleles which are present in an organism.

ABO blood group shows multiple allelism which means it has more than two alleles which are A, B, and O. A and B alleles show co-dominance and O allele is recessive allele.

As per the information, Mrs. Smith has blood type A (genotype of Mrs. Smith could be AA/AO), and Mr. Smith has a blood group B (genotype could be BB/BO).

The blood group of the first child produced is AB. So, the genotype of this child is AB only. And, the blood group of their second child is O which is recessive. So, the genotype of the child will be OO only (homozygous).

Therefore, the genotype of the parents Mrs. Smith and Mr. Smith for their children to have blood group AB and O must be AO and BO only.

Explanation:

Pathogens are disease causing organisms in the body. They attack diverse cells, organs, tissues and systems in the body thereby causing them to malfunction (to become diseased).

Antibodies are the body's natural protective mechanism against pathogens.  Antibodies engulf these pathogens and digest them. Then they produce certain chemicals called antitoxins which now destroy the toxins produced by these pathogens in the body.

Also they activate the systems involved in fighting pathogens by punching the cell wall of invading pathogens.

Answer:

The answer is A.

Bacteria, which are prokaryotic cells are single-celled entities that are primitive in structure and function as they lack a membrane-bound nucleus and other organelles.

Eukaryotic cells are the cells that are complex in structure and function as they have a membrane-bound well-defined nucleus and other membrane-bound organelles.
