For the Hill Reaction, you used DCIP dye at a concentration of 1x10-4 M. Our lab technicians have stock solution at a concentration of 100mM. Explain how you would make 100mL of the DCIP for you to use in a Hill Reaction lab.

Answers

Answer 1

Answer:

by diluting the DCIP dye stock solution 1000 times. It can be done by diluting 0.1 ml of the DCIP dye stock solution with 99.9 ml of distilled water

Explanation:

1 millimolar (mM) = 0.001 M

1.0 × 10⁻⁴  Molar (M) = 0.0001 M = 0.1 mM

Stock solution = 100 mM = 0.1 M

100 mM DCIP dye solution diluited 1000 times  >> 0.1 mM = 1 x 10⁻⁴ M

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.

During the process of DNA replication, a complementary DNA strand is formed. If the original strand of DNA is 5 ATA GTG CCC AAC GGT 3 which of the following would be the correct complementary DNA strand?
3. ATA GTG CCC AAC GGT 5
3 TAT CAA GGG TTG CCA 5
3 TAT CAC GGG TIG CCAS
3 TAT CAC GGG TTG CCT 5

Answers

Answer:

the third one

Explanation:

DNA replication produces two duplicated semi-conservative daughter strands. The complementary DNA strand of the original sequence will be, TAT CAC GGG TTG CCA. Thus, option c is correct.

What is DNA replication?

DNA replication is the process where the parent DNA strand forms two daughter strands that are semi-conservative and complementary to the DNA molecule. The complementary base pairing rule is used to produce the leading and lagging strand.

The complementary base pairing rule states the bonding between a purine and pyrimidine molecule. Accordingly, adenine base pairs with thymine, and guanine base pairs with cytosine.

Parent strand: 5' ATA GTG CCC AAC GGT 3'

Complementary strand: 3' TAT CAC GGG TTG CCA 5'

Therefore, option c. 3' TAT CAC GGG TTG CCA 5' is the complementary sequence.

What is the probability of short beaks in the offspring of the cross show above

Answers

Answer:

8/16 or 1/2

Explanation:

This question is a dihybrid cross involving two genes, one coding for feather color and the other for beak length. The alleles for green feathers (G) and long beak (L) are dominant over the alleles for yellow feathers (g) and short beak (l).

According to this question, a male with genotype GGLl was crossed with a female with genotype Ggll. The following combination of gametes is produced by each parent:

GGLl - GL, Gl, GL, and Gl

Ggll - Gl, Gl, gl and gl

Using these gametes in a punnet square (see attached image), the following offsprings in the following proportions will be produced.

Green feathers, long beak (GGLl, GgLl) = 8/16 or 1/2

Green feathers, short beak (GGll, Ggll) = 8/16 or 1/2

Hence, the probability of short beaks (ll) in the offspring of the cross is 1/2.

A human skin cell is observed. It is found to have two distinct nuclei each having 46 unreplicated chromosomes. These observations would be seen if the cell is in____.
a. G2 of interphase
b. metaphase of mitosis
c. S of interphase
d. telophase of mitosis
e. prophase of mitosis

Answers

Answer:

c

Explanation:

During the telophase stage of mitosis, a cell is observed with two distinct nuclei with 46 unreplicated chromosomes. Thus, the correct option is D.

What is Mitosis?

Mitosis is the process of cell division by which a cell replicates its chromosomes (genetic material) and then segregates that into two daughter cells, producing two identical nuclei in preparation for the division of cell. Mitosis is followed by equal division of the cell's content into two daughter cells with the identical genomes.

During the telophase stage of cell division, the spindle fibers attached to chromatids disappear. Once the daughter chromosomes arrive at the poles, a nuclear envelope starts reappearing around each set of chromosomes. And, at the end of telophase stage of mitosis, there are two nuclei in one cell, known as daughter nuclei that contains an exact copy of chromosomes.

Therefore, the correct option is D.

Explain the relationship between DNA sequence, amino acid sequence, and protein structure and function.

Answers

Answer:

The sequence of DNA may be associated with the sequence of amino acids, and the sequence of amino acids to the three-dimensional shape of the protein. It is the sequence of DNA, which provides the code for the amino acid sequence, and the sequence of amino acids further determines the protein structure that further influences the function of the protein.

When the sequence of DNA changes it causes a change in the sequence of mRNA, further resulting in the change in the sequence of DNA's nucleic acid and the sequence of amino acid. The sequence of amino acids of a protein is accountable for the composition of the protein. The composition of a protein is accountable for its function. The function and composition of a protein are primarily accountable for the organism's trait.

The functions and names include adding nucleotides to form an RNA (RNA polymerase), binding DNA for promoting transcription (transcription factors), and stopping transcription at the termination sequence.

What is transcription?

Transcription is the cellular process by which a code in the genetic material (DNA) is passed to another nucleic acid called RNA.

During gene transcription, a fragment of DNA called gene is used as a template to create a messenger RNA.

Subsequently, this mRNA is then used as a template to create a protein by a process called translation.

In conclusion, the functions and names include adding nucleotides to form an RNA (RNA polymerase), binding DNA for promoting transcription (transcription factors), and stopping transcription at the termination sequence.
