b) UAC- AGA - GGU -
UCG - AUC
c) AUG- UCG- CCA- AGC- UAG
Explanation:
A) The DNA sequence in this question is given as follows: 3 TÁC -AGA - GGT -
TCG - ATC 5'. This sequence undergoes transcription and translation (gene expression) in order to give rise to an amino acid sequence.
The mRNA sequence that will result following transcription is: AUG- UCU- CCA- AGC- UAG
Following translation, each codon in the above mRNA sequence will result in the following amino acid sequence: Methionine- Serine- Proline- Serine- STOP.
B) Anticodons are a group of three nucleotides that are complementary to a codon found on the tRNA molecule. The anticodons for each codon on the mRNA sequence is: UAC- AGA - GGU -
UCG - AUC
C) Silent mutation is a type of substitution mutation in which one or more nucleotide base is replaced by another in such a way that it does not change or alter the amino acid sequence. Using the mRNA sequence: AUG- UCU- CCA- AGC- UAG
A mutated sequence is as follows: AUG- UCG- CCA- AGC- UAG. Note that, G has replaced U in the second nucleotide. However, there is no change in amino acid that results because the same UCU that codes for SERINE is also encoded by UCG.

Label the structures of the hair follicle. Hair matrix Glassy membrane Cortex of hair Internal root sheath Differentiation zone External root sheath Connective tissue sheath Reset Zoom
Answers
Hair follicles are tubular invaginations of the epidermis, that develop as down growths of the epidermis into the dermis. Hair is made up of columns of dead keratinised cells.
Brief about the layers of hair?
Hair has three layers: a central medulla or nucleus (not found in fine hair) surrounded by a keratinized cortex and a thin, stiff outer cuticle that is heavily keratinized. This is the outer third layer to form. These keratinized layers are produced by cell proliferation in the hair matrix cells at the base of the hair follicle.
Around the hair towards the base of the hair follicle is the inner root sheath, which consists of the keratinocytes of the hair matrix. The type of keratin here is softer than the keratin in your hair and the same as on the surface of your skin. This cell layer dissolves where the ducts of the sebaceous glands enter the hair.
There is an outer root sheath around the inner root sheath. This is a tubular invagination of the epidermis that does not participate in hair formation. Finally, it is separated from the surrounding connective tissue by a hyaline basement membrane.
Therefore, Hair follicles are tubular invaginations of the epidermis, that develop as down growths of the epidermis into the dermis. Hair is made up of columns of dead keratinised cells.

Which of the following is true of the Sanger sequencing method?A) Requires an RNA template to copy.B) Incorporates dNTPs using an RNA polymeraseC) Requires a primer for the polymerase to extend from. This primer is radiolabelled so the sequences generated can be visualized.D) Requires chain terminating ddNTPs which are lacking a 2
Answers
The correct answer is D) Requires chain terminating ddNTPs which are lacking a 3’OH group, causing DNA synthesis to terminate at specific positions.
The Sanger sequencing method, also known as the chain termination method, is a widely used DNA sequencing method that involves the use of chain terminating ddNTPs, which are labeled with different fluorescent dyes to distinguish the different nucleotides. The method requires a DNA template, a primer, DNA polymerase, and all four dNTPs, along with the chain terminating ddNTPs. The DNA synthesis process is terminated when a chain terminating ddNTP is incorporated into the growing strand, resulting in a set of differently sized fragments that can be separated by gel electrophoresis and read by a DNA sequencer. This method revolutionized the field of genomics and was instrumental in the sequencing of the human genome. The Sanger sequencing method has been one of the most important methods in molecular biology, allowing researchers to decode DNA sequences with high accuracy and efficiency.

Answers
Answer:
a certain sugar has no change in color when tested with benedict solution. can you tell which saccharide it is? no because it could be poly or disaccharide. what is the chemical formula for a polysaccharide molecule that contains 4 glucose molecules?
Sucrose
Sucrose (table sugar) contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose undergoing isomerization to an aldehyde, or fructose to alpha-hydroxy-ketone form. Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent.
Explanation:
Sugars which give no color in Benedicts test are non-reducing sugars. Sucrose, a non reducing sugar does not undergo a color change in Benedict's test.
What is Benedict's solution?Benedict's solution is a chemical reagent containing copper sulphate pentahydrate and mixtures of sodium carbonate and sodium citrate. It is used to test the presence of reducing sugars.
A positive Benedicts test gives color change of blue to brick red precipitate whereas, non-reducing sugars does not give a positive result.
Sucrose contain fructose and glucose, they do not reduces the copper ion in Benedict's solution because there are no free aldehydes or ketones in sucrose.
Thus, sucrose does not reduce and will not give a color change in Benedict's test.

inhibitor of glyceraldehyde-3-phosphate dehydrogenase, which glycolytic intermediates would accumulate?
Answers
Glycolytic intermediates that would accumulate in the presence of an inhibitor of glyceraldehyde-3-phosphate dehydrogenase include glyceraldehyde-3-phosphate, dihydroxyacetone phosphate, and fructose-1,6-bisphosphate.
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is an enzyme that catalyzes the first step in glycolysis, converting glyceraldehyde-3-phosphate (G3P) into 1,3-bisphosphoglycerate (1,3-BPG). An inhibitor of GAPDH would cause G3P to accumulate and slow down glycolysis, the process by which cells convert glucose into energy.
The accumulation of G3P would likely be accompanied by a decrease in the production of ATP, the energy currency of cells. The inhibition of GAPDH could have both positive and negative effects on cellular processes, depending on the context and the specific system being studied.

Explanation:
Natural processes like speciation create variation in species, making them have biodiversity and a diverse gene pool.
Gradualism also allows for species to change gradually over time.
Both of these processes allow for evolution to occur, as speciation can create more favorable traits that will be passed down with the process of gradualism.
So, the correct answer is A, evolution.
Natural processes such as speciation and gradualism provide the genetic basis for evolution. Thus, option A is correct.
What is speciation?Natural processes like speciation create variation in species, making them have biodiversity and a diverse gene pool. Gradualism also allows for species to change gradually over time.
Both of these processes allow for evolution to occur, as speciation can create more favorable traits that will be passed down with the process of gradualism.Traits may be defined as the appearance or manifestation of a character. In genetics, traits are also known as Phenotypes.
Natural selection always carries their successful or most favorable traits into the next generation and eliminates the unsuccessful or least favorable traits. Or in other words, natural selection states the occurrence of the most favorable variations.
