Answer:

The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.

Problem Set 4 Answers

1a. The template DNA strand, from which the mRNA is synthesized, is 5’ CAAACTACCCTGGGTTGCCAT 3’

(RNA synthesis proceeds in a 5’ à 3’ direction, so the template strand and the mRNA will be complementary to each other)

b. The coding DNA strand, which is complementary to the template strand, is 5’ ATGGCAACCCAGGGTAGTTTG 3’

c. The sequence of the mRNA is 5’ AUGGCAACCCAGGGUAGUUUG 3’

(the sequence of the mRNA is complementary to the template strand and identical to the coding strand with U substituted for T)

d. The third codon is 5’ ACC 3’. Therefore, the corresponding anti-codon is 5’ GGU 3’

The complementary strand will read TAA-GGG-CGT since the A is complementary to T and C is to G nucleotide.

A biological molecule known as a nucleotide has the basic building blocks of a nitrogenous base, pentose sugar, and phosphate. As polynucleotides, DNA and RNA are composed of a chain of monomers with various nitrogenous bases. The execution of metabolic and physiological processes requires nucleotides.

Building blocks of nucleic acids, energy storage, carriers of activated metabolites for biosynthesis, structural moieties of coenzymes, and metabolic regulators are all roles that nucleotides play in the physiology of animals.

Adenine and thymine and guanine and cytosine are the proper bases to couple with in DNA. Therefore, the complementary strand will read TAA-GGG-CGT since the A is complementary to T and C is to G nucleotide.

Answer:

Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.

Answer:

BLOSUM

Explanation:

A substitution matrix is a matrix used in bioinformatics (and also in computational biology) to determine/estimate the rate at which one character -which is specified by a nucleotide sequence in nucleic acid alignments or by one amino acid in protein alignments-, changed to another character during the course of the evolution. The BLOcks SUbstitution Matrix (popularly known as BLOSUM) is a substitution matrix used to score one amino acid for another in a protein alignment. The BLOSUM substitution matrix is particularly useful to compare evolutionarily conserved regions between protein sequences and thus score their alignments, where each entry is indicated by a similarity score between two amino acids.

The chemical equation of cellular respiration comprises information regarding the relative amounts of products and reactants.  

• The process, which takes place within the mitochondria of all the organisms is termed cellular respiration. In this process, the simple sugars are dissociated into water and carbon dioxide and release energy in the form of ATP.  

• A chemical reaction is a procedure in which one or more components, that is, the reactants get transformed into one or more different components called the products.  

• The substances, which start the reaction are called reactants, while the ones that get produced in the reaction are called products.  

• The association between the reactants and products in a chemical reaction can be signified with the help of a chemical equation.  

Thus, the chemical reaction of cellular respiration comprises information regarding the relative amount of products and reactants.

(C) DHM promotes apoptosis in cancer cells.

Explanation:

Since some cancers are caused by a lack of apoptosis (programmed cell death), DHM treats cancer by forcing apoptosis to occur in cancer cells, stopping their growth and division.

The choice which best describes a possible mechanism of action for this cancer drug is DHM promotes apoptosis in cancer cells. The correct option is C.

DHM is a chemical that is present in the plant, Hovenia Dulcis grow in Japan. It is a raisin plant and has several medicinal values. It is used in East Asia as a hangover medicine.

Apoptosis is a process of cell death, so if DHM promotes apoptosis in the cancerous cells, then it will reduce cancer by killing the cancer cells.

Thus, the correct option is C, DHM promotes apoptosis in cancer cells.

Cloning vectors.

Explanation:

Viruses are use as cloning vectors because they can give the new gene or birth the new gene by infecting the cell. They are so modified and orogrammed in such a way that they cannot cause disease when it is used in humans. Cloning vector is a DNA fragment gotten from viruses or bacteria plasmid which is maintained and used for cloning purposes.

Answer:

They are antiparallel

Explanation:

They are antiparallel because one strand of 3' faces the end of 5' of another strand and 5' end of one strand faces 3' end of another strand. Which indicate that 5 phosphate group faces the end of 3 hydroxyl group and they are of opposite directions to each other because it has opposite polarity with each other .

Genotypic ratio F2 = 1:2:1

Phenotypic ratio F2 = 3:1

Explanation:

In this case, parental genotypes can produce only one type of gamete, i.e., one parent can produce only D gametes, while the other parent can produce only d gametes. Therefore, all F1 generation will be heterozygous (Aa). An F1 hybrid is the first filial generation of offspring obtained from crossing between different parent types. The F1 will produce two gametes (A; a) in a ratio 1:1, thereby the F2 obtained by crossing F1 offspring will have a phenotypic ratio of 3:1 (3 D_; 1 dd) and a genotypic ratio of 1:2:1 (1 AA; 2 Aa; 1 aa).
