What is a DNA probe?

Answers

Answer 1

Answer:

In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length which can be radioactively or fluorescently labeled. It can then be used in DNA or RNA samples to detect the presence of nucleotide substances that are complementary to the sequence in the probe.DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleic acid sequences (target sequences) by hybridization. DNA probes are usually labelled, for example with radioisotopes, epitopes, biotin or fluorophores to enable their detection.

En biología molecular, una sonda de hibridación es un fragmento de ADN o ARN de longitud variable que puede marcarse de forma radiactiva o fluorescente. Luego puede usarse en muestras de ADN o ARN para detectar la presencia de sustancias nucleotídicas que son complementarias a la secuencia en la sonda. Las sondas de ADN son tramos de ADN monocatenario utilizados para detectar la presencia de secuencias complementarias de ácido nucleico (secuencias diana) por hibridación Las sondas de ADN generalmente están marcadas, por ejemplo, con radioisótopos, epítopos, biotina o fluoróforos para permitir su detección.

Answers

Answer:

They create a Mountain Peak

When multiple glaciers start their downward flow from a single point, they create a Mountain peak. So, the correct option is B.

What are Glaciers?

A glacier is a sizable, slowly moving mass of ice that develops over a considerable amount of time as a result of the buildup of snow and ice. In areas where the average temperature is below freezing and there is enough snowfall to offset the melting that takes place during the summer, glaciers can be discovered. They can occur at lower elevations in some places, although they are mainly found at high altitudes or in the polar regions.

When several glaciers begin to flow downward, they build something resembling a pyramid. The mountain peak is created as a result of the glacier's movement from a single location. Due to the simultaneous movement of several glaciers to the ground, a pointed structure has recently created.

Therefore, the correct option is B.

Which statement is true of DNA polymerase?



Answers

Answer:

b) DNA polymerase can synthesize DNA in the 5' to 3' direction

DNA polymerase is only able to synthesize a new strand of DNA and not mRNA. It is only able to do this in the 5' to 3' direction. The leading template strand runs in the 3' to 5' direction and so the new complementary strand is synthesized in a 5' to 3' direction in one continuous run, following the replication fork as it 'unzips' the DNA.

In the previous activity, you chose an animal that interested you and listed three examples of innate behavior and three examples of learned behavior for that animal. Now research what, if any, courtship and mating rituals this animal has. Explain why you think it has or doesn’t have these behaviors.

Answers

Answer:

what grade

Explanation:

Courtship and mating rituals are diverse and can vary greatly among different animal species. They are typically involved in attracting mates, establishing pair bonds, and ensuring successful reproduction.

1. Courtship and Mating Rituals Exist: Many animal species have elaborate courtship and mating rituals. These behaviors can serve various purposes, such as displaying fitness and attractiveness to potential mates, establishing territory, or demonstrating parental abilities.

2. Absence of Courtship and Mating Rituals: Some animal species may not exhibit elaborate courtship or mating rituals. This can occur in species where mating opportunities are abundant or where the reproductive process is straightforward without the need for elaborate displays.

The presence or absence of courtship and mating rituals can depend on various factors, including ecological pressures, social structure, reproductive strategies, and evolutionary history of the species. Different species have evolved different strategies to maximize their reproductive success, and these strategies can manifest as complex courtship rituals or simpler methods of attracting mates.

What is cell reproduction?

Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body. The cell division process known as meiosis is what produces egg and sperm cells.

A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis.

Meiosis, the second sort of cell division, makes sure that each generation of people has the same number of chromosomes.

Identify the strengths and weaknesses of Mendel’s Law of Independent Assortment.

Answers

Answer:

Explanation:

Mendel propel two laws The law of inheritance and that of independent assortment of gene.

Independent assortment of gene explain that alleles of a gene assort independently and that different Allele can show different phenotypic effect and differences. This means that in a gene where we have 2 allele they can both show individual difference where one can have a dominant effect over the other and the other allele is recessive.

This law does not take care of linked gene where alleles don't separate after crossing over sister chromatids but are rather inherited together given rise to complex inheritance.
