All cell organisms have this chain of nucleotides that give them a unique coding that helps everything differ from one another. Whether within plant or animal cells, these coding strands contain our genetic information. The creation of our genetic codes derives from a mixture of our parent genetic codes. These codes we contain are called DNA, also known as deoxyribonucleic acid. These DNA strands carry all our information. Skin color, eye color, body shape, hair type, etc. This creates us…
I. Introduction to The C-Value Paradox C-Value is defined as “the amount of DNA per haploid cell or the number of kilobases per haploid cell at any given time” (Swift 1950). The C-Value Paradox states that C-Value or genome size does not always equal the number of genes contained within the genome or complexity of the organism. Order of magnitude is when more DNA than what is necessary to encode for proteins. The prokaryotic genome is much simpler than the complex genome of the eukaryote yet…
prophase, metaphase, anaphase, and telophase. The stages of which are interphase, prophase, metaphase, anaphase, and telophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope breaks down. The centrioles near the nucleus begin to separate and move to opposite poles of the cell. Then during metaphase spindle fibers attach to the centromere of each pair of…
• The nucleolus is a darker staining region of the nucleus. It is non-membrane bound structure composed of ribonucleic acids (RNA) and proteins. It makes ribosomes inside the nucleus and contains all the DNA of the cell. It is also used for cellular reproduction and it is often referred to as the brain of the cell as it controls what goes on. Golgi apparatus A group of fluid-filled flattened membrane bound sacs located close to the nucleus. Vesicles are regularly seen at the sacs' edges.…
The one letter abbreviations for my chosen DNA was MRFRFGVVVPPAVA which it’s protein name is Laforin Isform. The protein Laforin Isform is connected to the disease Lafora disease (LD). This is a autosomal resessive, progressive myclonus epilepsy. This Progressive myclonus epilepsy has different amount of diseases which end up causing muscle contractions and seizures. This disease manifest during adolescence with tonic-clonic seizures, myclones,absence, visual hallucinations and drop attacks…
The nucleolus which is also known as the brain of a cell, is the most significant part in the nucleus. It takes up about 25 percent of the nucleus and it is not surrounded by a membrane. Through a microscope, the nucleolus is a big dot in the middle of it. It can be found in an animal, plant, diploid, and eukaryotic cell. It was found in the eighteenth century but its function wasn’t discovered until the 1960s. The nucleolus lives in the nuclear matrix. Sadly, the nucleolus is one of the…
Nucleus: The nucleus is the control centre of the cell. It’s much like a blueprint that contains all of the instructions on building the body. It contains genetic material called DNA. This DNA has instructions for building proteins and is essential to cell reproduction. If a cell doesn’t have a nucleus for whatever reason will certainly die. The nucleus conforms to the shape of the cell so it could be oval or it could be spherical. The nucleus has three recognizable regions; the nuclear…
The results in this lab for Interphase had twenty cells, Prophase had ten cells, Metaphase had three cells, Anaphase has two and last Telophase, which had only one cell. The results shows that Interphase took the longest for completion and Prophase was the second longest for completion. Telophase took the shortest time for completion. The percentages for each mitosis stage and Interphase was fifty-six percent for Interphase, twenty-eight percent for Prophase, eight percent for Metaphase, six…
Deoxyribonucleic acid (DNA) is the hereditary material. It is a polynucleotide and is a double helix composed of two strand that run in opposite direction1. Each strand of DNA consist of a sugar molecule (deoxyribose), nitrogen base (adenine-A, guanine-G, thymine-T and cytosine-S) and a phosphate group. Adenine and guanine are double-ringed molecules known as purines while thymine and cytosine are single-ringed molecules known as pyrimidines1. Within the DNA molecule, the sugar molecules are…
1.3 Histone variants Histone variants are non-allelic isoforms of core histones that have specialized functions resulting from its distinct amino acid constitution. All histone families except for H4 histone have variant forms (Kamakaka and Biggins, 2005). Unlike core histones, which are only expressed during S phase, histone variants are continuously expressed throughout the cell cycle and incorporated into DNA in a replication-independent manner (Sansoni et al., 2014). A great number of…
