then the bonds were broken and a single strand of DNA was created. The single strand was then open to having ribonucleotides attached to it, in which a mRNA was then modeled. In theory, after the construction of the mRNA, it would pass into the cytoplasm and be translated into an amino acid sequence and converted to tRNA. After we modeled the tRNA an amino acid would attach onto the strand come together until the protein is…
This step takes place in the cytoplasm of cells and is anaerobic which means it does not require the presence of oxygen. The runner eats a meal before the race and their body uses the glucose from the food to start glycolysis. In glycolysis the runner’s body takes the glucose and uses…
metaphase II, meiosis will be fixed if the egg is ‘fertilised’. In females the meiotic divisions are usually leading to producing two polar bodies at the same time meiosis completes the job. In spermatogenesis the more the mitochondria is the less the cytoplasm,but in oogenesis the less the mitochondria the more the…
when tested for identification. If its cell wall is thin and stains red, it is referred to as gram negative. Under the cell wall, the bacterium also has a plasma membrane made up of a phospholipid bilayer with proteins inserted inside. Within its cytoplasm, ribosomes for protein synthesis and a single DNA strand are…
cells reach the beginning of prophase |, start synapsis and crossing over, and there remain at this phase for years. Meiosis is completed during ovulation. The ova is the half of the split nucleus that is larger and contains the majority of the cytoplasm, the other half is the polar body. At completion, three polar bodies have been formed. One stem cell results in one ova within the female, and four sperm cells within the male. E. Number of Functional Gametes Formed by a Single Cell Division -…
still do share some characteristics. No matter at which cell you are looking at: bacteria’s`, plants`, animals`, protists`, etc., they all will be bounded by a plasma membrane (Biology Department,2015), and contain a nucleic acid: such as DNA, RNA, cytoplasm, and ribosomes. The things that prokaryotes will not have are organelles. Organelles can be known as the parts of the cell, such as: Nucleus, ER, Golgi apparatus, etc. There are there domains that exist: Bacteria, Archaea and Eukarya(Biology…
Prokaryotes can be recognized as a single-celled organism that lack the extensive internal compartments. Unlike eukaryotes, the prokaryotes concentrated their genetic materials in a small portion of cell’s cytoplasm known as nucleoid. Almost entire prokaryotic genome is contained in a single circular DNA strand that is supercoiled. Some additional genes are located on an independent small, circular or linear plasmids which coding for extra properties likes antibiotic resistance (Brown, 2002).…
would just wind up to create a double helix. Transcription is making RNA part of a gene sequence. This is when DNA is copied into RNA which would make it a messenger RNA (mRNA). The Mrna molecule is able to leave the nucleus and go to the cytoplasm where it sends messages for the synthesis of…
functions. The cell is made up of two major parts which include the nucleus and the cytoplasm. The nucleus is surrounded by a nuclear envelope, which can also be referred to as the nuclear membrane which is a bilayer membrane that encloses the contents of the nucleus throughout the lifecycle of the cell. The membrane of the cell is selectively permeable meaning that it only allows certain things to go in and out. The cytoplasm which is surrounded by…
water (Wikipedia, n.d.). In the glycolysis stage of the process, there is one glucose molecule that is in the cell’s cytoplasm, and…
