does RNA play a role similar to enzymes? RNA is like an enzyme when it is a catalyst and helps assist in the reduction of the activation energy which relates to tRNA when it attaches its amino acid to the rightful place. This helps construe a faster translation. 3. Are all genes expressed at all times? Explain your

Biochemistry of Proteins; Isolation of Ovalbumin and Enumeration of thiol groups Abstract Thiol groups are important to protein folding and forming disulphide bonds that are essential to protein structure. Determining the number of thiol groups in a protein is important in determining the tertiary structure of the protein. The ovalbumin is the experiment was purified from egg white using centrifugation and ammonium sulphate precipitation and then the thiol groups identified using DTNB and spectroscopy

The Ted Talk video entitled “Animations of Unseeable Biology” describes the process of DNA replication. As the speaker Drew Berry explains‚ this process is repeatedly occurring and is performed mechanically. He provides us an animation of how a chromosome is replicated and split with the help of microtubules. Microtubules are straight tubes that are made up of proteins and it resides within a cell. This hollow tube allows the mitosis phase to occur. The copying of DNA is transported across the microtubules

Reproduction among various species is a key part of studying genetic of inheritance between individual species and their offspring. Genetics have discovered the structures that can simply be studied. The model that is being studied is in a domestic pest that may be found throughout decaying food. The topic that is being examined is the Drosophila. When Drosophila is prepared for mating or hatching‚ they have a full lifecycle of about 20 days‚ thus are the models for relating sex-linked inheritance

Macroautophagy‚ a cellular process regulated by p53 is an intracellular system that involves the break down of cytoplasmic contents within the lysosome. This mechanism is a form of adaptation to cellular stress such as starvation‚ trophic factor deprivation‚ hypoxia‚ endoplasmic reticulum (ER) stress and oxidative stress (Levine & Abrams‚ 2008). Through adaptation‚ it allows the prevention of cell death. There are three types of autophagy: macroautophagy‚ microautophagy‚ and chaperone-mediated autophagy

As stated above the androgen receptor-coding gene is located in band Xq11-q12 on the long arm of the (X) chromosome. This portion of the X chromosome is about 90kb and contains 8 exons that code 919 amino acids with a mass of approximately 110kDa. These many amino acids determine the structure of the transcription factor protein involved in steroid-hormone activation. The androgen receptor has several functional domains‚ which are inconsistently classified among various literature. In general the

Abstract: Using genes that control development makes it possible to identify mutants that alter development. Anterior –Posterior axis formation is controlled by protein gradients in the early embryo development. Bicoid and nanos mRNAs are both maternally provided and are localized to opposite poles of the embryo (Springfield‚ 2016). Bicoid proteins are concentrated at the anterior end and nanos proteins concentration is highest at the posterior end of the embryo (Springfield‚ 2016). The combination

Comparison of Sanger Sequencing and Illumina Sequencing Technique In similarities‚ Illumina or NGS (Next Generation Sequencing) is principle based similar to Sanger Sequencing. Re-synthesizing the bases of DNA small fragment from a DNA template strand that is identified from the emitted signal. But unlike Sanger Sequencing‚ Illumina NGS sequencing further the process in a huge parallel fashion across millions of action instead of being limited single of a few DNA fragment like Sanger Sequencing

A. Proteins- A protein is a naturally produced macromolecules that are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and chains of amino acids. The amino acids are building blocks for all our cells. Proteins main function is to help in tissue repair and growth. There are three different types of proteins. Fibrous proteins help in forming muscle tissues‚ tendons‚ bones‚ and connective tissue and some examples of these are Actin‚ Coronin‚ Elastin‚ and Myosin. Globular proteins help in regulating

Ligation is the process of joining two DNA fragments or other molecules by a phosphate ester linkage with the action of enzyme. Ligation of DNA is process that involve the DNA of interest is inserted into the plasmid. This 3’-hydroxyl of DNA terminus are joined together with 5’-phosphoryl of another by phosphodiester bond. The ligation of DNA fragments usually performed by using T4 DNA ligase. All the reaction components such as ligation buffer‚ DNA insert‚ pGEM®-T‚ and T4 DNA ligase is mixed by
