Polymerase Chain Reaction (PCR) technology is used for

a. DNA identification
b. DNA repair
c. DNA amplification
d. DNA cleavage​

Answers

Answer 1

Answer:

The correct answer is c.

Explanation:

Polymerase Chain Reaction (PCR) technology is an in vitro enzymatic method that allows the amplification of a specific DNA sequence, that is, it is the DNA amplification technique by means of the polymerase chain reaction (PCR) is a technique that consists of the in vitro amplification of a specific DNA fragment. To carry out the amplification experiment, it is necessary to know, at least partially, the sequence of the fragment to be amplified (a gene, a part of a gene, a non-coding region, ...). Basically, it is about replicating the same DNA fragment over and over again and, for this, we must do in vitro what cells do in vivo to replicate their DNA. Generally, PCR begins with the denaturation or separation of the DNA double helix by heating the sample to a temperature between 94 and 96 ° C to break the hydrogen bonds that joined them, in this way each chain remains as a template for the synthesis of a new complementary strand of DNA.

Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure

Answers

"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!

#followandheartallmyquestion

When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.

Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:

the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.

Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.

The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.

An inflated basketball hold 6 liters of air at 3 ATM. How much air at 1 ATM went into the ball

Answers

Answer:

18 litres

Explanation:

Using Boyle's law equation as follows:

P1V1 = P2V2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (litres)

V2 = final volume (litres)

According to the information in this question, An inflated basketball hold 6 liters (V1) of air at 3 atm (P1). The volume of air (V2) at 1 atm (P2) that went into the ball can be calculated thus:

Using P1V1 = P2V2

3 × 6 = 1 × V2

18 = V2

V2 = 18 litres.

The process of meiosis is essential in the sexual reproduction and life cycle of many organisms. The outcome of meiosis is haploid gametes. Which statements correctly describe the importance of meiosis to the life cycle or these organisms?
A) Increasing genetic diversity ensures that no two haploid gametes are exactly the same.
B) Taking a diploid cell to its haploid state occurs during the first cell division of meiosis.
C) Checkpoints during meiosis ensures that chromosome separation occurs accurately, avoiding non-disjunction.
D) DNA synthesis occurs before each cell division in meiosis ensures that the integrity of the chromosomes is maintained.
E) Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization.

Answers

Answer:

E) Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization.

A) Increasing genetic diversity ensures that no two haploid gametes are exactly the same.

Explanation:

Meiosis is a kind of cell division that strictly occurs in sexually-reproducing organisms. It is the process whereby four daughter cells that are genetically different from their parents are produced. In meiosis, the chromosome number of each daughter cell (gamete) is reduced by half. As highlighted in this question, the meiotic process is essential in the sexual reproduction and life cycle of many organisms.

This importance is attributed to the fact that:

- Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization. That is, a diploid organism (2n) produces a haploid gamete (n), which becomes diploid again when fertilized by another gamete.

- Increasing genetic diversity ensures that no two haploid gametes are exactly the same. This occurs because of a process called CROSSING OVER, which enables that the alleles of each gamete is recombined to be different from one another in order to promote genetic diversity.

b) Forming zygots

Explanation:  

A zygote can be defined as a eukaryotic cell formed by the fusion of gametes during sexual reproduction. In general, a zygote is a diploid (2n) cell produced by the fusion of two haploid (n) gametic cells (eg., in mammals, sperm and egg cells). In multicellular organisms, the zygote is the first stage of development, which will give rise to an adult organism as it divides and grows. A zygote cell can be considered as a pluripotent stem cell because it differentiates into all cell types.

In normal cells the amino acid phenylalanine attaches to tRNAs with the anticodon AAA. The enzyme aminoacyl-tRNA synthetase catalyzes the reaction that attaches the amino acid to the correct tRNA. Assume that a mutation occurs in the aminoacyl-tRNA synthetase enzyme and causes it to attach lysine instead of phenylalanine to tRNAs with the anticodon AAA. What will be the consequence of this mutation for the translation process

Answers

Answer:

Aminoacyl-tRNA bond is hydrolyzed.

Explanation:

The consequence of this mutation for the translation process is the hydrolysis of aminoacyl tRNA bond occur.  If the incorrect amino acid is attached to other molecule as a result of this reaction, the aminoacyl-tRNA bond is hydrolyzed. This incorrect binding of amino acid occur because of mutation in the aminoacyl-tRNA synthetase enzyme that leads to its hydrolysis.
