the role of the c. elegans mena/vasp homolog unc-34 in neuronal polarity and motility. [t. fleming, s.–c. chien, p.j. vanderzalm, m. dell, m.k. gavin, w.c. forrester and g. garriga (2010) developmental biology 344: 94-106.]
Answers
The given article "The role of the c. elegans mena/vasp homolog unc-34 in neuronal polarity and motility" has mentioned the molecular and developmental study of how unc-34 genes affect the nervous system of Caenorhabditis elegans, a small nematode.
The article explains how the unc-34 genes are responsible for the coordination and directionality of the growth of axons and dendrites.
The paper in the given article describes the analysis of the role of the UNC-34 protein in the axonal and dendritic growth of the neuronal cells of Caenorhabditis elegans.
As per the article, the UNC-34 protein belongs to a family of conserved actin-binding proteins known as Ena/VASP (Enabled/vasodilator-stimulated phosphoprotein).
The UNC-34 gene encodes a homolog of Ena/VASP in the nematode C. elegans.UNC-34 protein and its homologs are required for the coordinated extension of filopodia and lamellipodia in a variety of cell types and organisms.
They regulate actin dynamics, leading edge protrusion, and cell motility.
In this study, the role of the UNC-34 protein in neuronal polarity and motility was examined in the nematode C. elegans. It was found that the UNC-34 protein is involved in the formation of axons and dendrites, as well as the directional growth of neurites.
Additionally, it was observed that the UNC-34 protein is required for the migration of neurons to their final positions.
The study indicates that UNC-34 plays a significant role in neuronal polarity and motility in C. elegans. It regulates the development of neurites and the directional growth of axons and dendrites. It also facilitates neuronal migration to their final positions.
Thus, the research highlights the importance of Ena/VASP homologs in the development of the nervous system.

C. Origin of species by August Weismann
D. Lamarck’s theory of acquired characters
Answers
Darwin was most influenced by B. Thomas Malthus's work on population.
Darwin spent 20 years in seclusion studying the plants, animals, fossils, and geological formations he discovered on his journey. By comparing the flora and fauna of South America's eastern coast, the Galapagos Islands, and Australia, he found patterns of similarity between species, as well as variations between and within them.Darwin was influenced by the writing of several other authors, but the most significant was Malthus, who influenced Darwin's work by promoting the concept of struggle for existence. Malthus' theory emphasized that all animals compete for resources to survive. This was similar to what Darwin was seeing in nature, which convinced him that survival of the fittest was the mechanism behind the development of species. Therefore, Darwin was most influenced by B. Thomas Malthus's work on population.

Answers
Clades are based on relatedness; grades are based on physical traits.
A clade is a group of organisms that includes an ancestor and all of its descendants, based on their shared evolutionary history and relatedness.
Clades are typically defined based on the presence of certain unique features or shared derived traits, that indicate a common ancestry.
Grades, on the other hand, are groups of organisms that are classified together based on their physical traits or characteristics, such as morphology or behavior.
Grades are often used to describe groups of organisms that share similar adaptations or lifestyles, but may not necessarily be closely related in an evolutionary sense.
Therefore, the correct answer is that clades are based on relatedness, and grades are based on physical traits. The other options in the question are not accurate characterizations of these terms.

Answers
This process allows for genetic diversity through the exchange of genetic material between homologous chromosomes
Meiosis I is the first stage of meiosis, which is the process by which cells divide to form gametes (sperm and egg cells). During meiosis I, homologous chromosomes pair up and exchange genetic material through crossing over.
This results in new combinations of genetic material and contributes to genetic diversity.
Crossing over normally takes place during meiosis I.
During meiosis I, homologous chromosomes pair up and exchange genetic material through a process called crossing over, which increases genetic diversity.
This process does not occur during mitosis or meiosis II.

A _____ is a fluid-filled space between two neurons through which neurotransmitters travel. It is in this area where messages are transmitted chemically.
Answers
A synaptic cleft is a fluid-filled space between two neurons through which neurotransmitters travel. It is in this area where messages are transmitted chemically.
The synaptic cleft is a vital component of the synaptic junction, which is the point of communication between two neurons. When an action potential reaches the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, initiating a series of biochemical events that lead to the transmission of the message. The synaptic cleft acts as a physical and chemical barrier, ensuring that the neurotransmitters are specifically received by the appropriate receptors. This process allows for precise and controlled communication between neurons.

The multiple cloning site of a vector is within the lacZ gene. During the ligation of the gene of interest into this site the lacZ gene gets disrupted. Addition of X-Gal allows for screening. What is a correct description of a color result
Answers
A correct description of a color result would be the absence of blue coloration, indicating successful ligation and disruption of the lacZ gene.
The lacZ gene in the multiple cloning site of a vector is commonly used as a reporter gene in molecular biology experiments. It produces an enzyme called β-galactosidase, which can cleave a colorless substrate called X-Gal into a blue product. However, when the gene of interest is ligated into the multiple cloning site, it disrupts the lacZ gene, rendering it non-functional.
To screen for successful ligations, X-Gal is added to the system. If the lacZ gene has been disrupted by the gene of interest, β-galactosidase activity is lost, and the blue color is not produced. Therefore, a correct description of a color result would be the absence of blue coloration. This indicates that the lacZ gene has been disrupted, suggesting a successful ligation of the gene of interest into the vector.
This color-based screening method allows researchers to easily identify and select clones containing the desired gene of interest by visualizing the absence of blue color, providing a convenient and efficient way to screen for successful ligations in molecular cloning experiments.

percentage of thymine will each new strand have after replication?
A. 20%
B. 60%
C. 40%
D. 30%
Answers
Answer:
According to Chargaff's rule, if a DNA strand has 30% guanine before to semi-conservative replication, the percentage of thymine that will have each new strand after replication will be 20% (option A).
Explanation:
A DNA molecule stores the genome of a living organism in a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine. By knowing the percentage of a nitrogenous base in the DNA, the percentage of the other bases can be established using Chargaff's base pair rule.
Chargaff was able to establish that in a DNA molecule the ratio purine:pyrimidine is 1:1, so there must be the same amount of guanine as cytosine and a similar amount of adenine for thymine, taking into account the complementarity of the bases.
According to the base pair rule, if in a DNA strand there is 30% guanine, in the molecule there is:
Guanine 30%. Cytosine 30%. Thymine 20%. Adenine 20%. Total ..... 100%In this case, Chargaff's rule is useful to determine the percentage of thymine that each new strand will have after replication, corresponding to 20%.
