Jungle: The jungle is a vast land with dense vegetation and forest, generally located in tropical areas.
Jupiter: The biggest planet among all other nine planets in our Solar system is Jupiter. It takes the fifth position from the Sun and consists of swirling cloud stripes. Well, the five important facts about Jupiter include:
1) It is massive with the total amount of gas matter
2) It is never ever a star
3) The fastest spinning planet in the solar system
4) Surprisingly, it has 67 moons and rings with a magnetic field four times greater than Earth.
5) The clouds of Jupiter are 50m thick
Jet Stream: Jet streams are the fastest moving air current, present on very few planets of the solar system. However, Earth is one such planet that experiences the fastest air currents at the altitude of the tropopause. But these air currents are very weak in nature on Earth. Well, a meandering shape is the typical feature of these air currents.
Jovian Planet: There are two types of planets in our solar system. I.e. Jovian and Terrestrial planets. Jovian planets are a group of planets such as Uranus, Saturn, Neptune, and Jupiter. Anything related to Jupiter planet and Jupiter-like planets comes under this category.
Jejunum: Jejunum is the tiny part of the small intestine present in higher vertebrates such as mammals, reptiles, birds, and humans. The primary function of jejunum is to absorb small nutrient molecules such as amino acids, sugars, and fatty acids. This is because it consists of a special lining, which absorbs molecules using enterocytes. In addition, the jejunum is also specialized in absorbing materials that are not digested and absorbed by the duodenum. Forex: Vitamin B12 and Bile acids
Junction Cell: Junction cells are the intercellular bridges that help in the production of adhesive contact between one cell and neighboring cells. Well, it consists of multi-protein complexes to maintain the contact between the cells. Also, this adhesive contact helps to connect a cell with its extracellular matrix present in animals.
Junk DNA: Generally, DNA consists of genetic information and instructions i.e. coding regions and non-coding regions. Well, coding regions contain instructions to produce proteins in the cells whereas non-coding regions remain non-productive. However, these non-coding regions refer to junk DNA. As non-coding regions do not provide any information to produce proteins, scientists named them “junk”.
Still, the research is going on junk DNA to explore its functions and how far it is helpful in providing genetic information. According to scientific studies, the human body consists of 98% of junk DNA because these DNA sequences codes nothing and are useless. Hence, only 2% of DNA is coding DNA which actually codes for producing necessary proteins according to the coding instructions.
J-chain: The mucosal and glandular plasma cells express minor polypeptides in order to regulate the polymer formation antibodies, IgA (Immunoglobulin A), and IgM (Immunoglobulin M). Well, J-chain is one such tiny polypeptides with enough protein components of dimeric IgA and pentameric IgM from plasma cells. In fact, J-chain incorporation helps these antibodies in expressing a lot many features like linking the subunits of each multimer.
Jumping Gene: Jumping genes, otherwise known as ‘Transposons’ are the specific DNA sequences that jump from one place to another place within the genome. Such DNA sequences are transposable elements, capable to mutate or alter the genome’s size and genetic information of the cells. Mostly, because of the jumping nature of transposable elements, duplication of the same genetic information or sequences happens.
The reason for the jumping genes is to develop egg and sperm cells which plays important role in evolution. However, the same jumping genes may also lead to new mutations, which result in various diseases such as cancer and hemophilia.
Jumping PCR: PCR is a revolutionary technique in Biotechnology. Scientists use this technique to produce DNA sequences in large amounts using small or repaired DNA sequences. To put it simply, the reconstruction of repaired DNA sequences found in biological tissues or cells is the jumping PCR technique. There are two cycles in the PCR technique for reconstructing double-stranded DNA sequences. In the first cycle, every primer strand extends until it reaches the broken template. Whereas in the second cycle, newly synthesized strands develop at the damaged templates. In this way, both the cycles continue their functioning until they build new and continuous DNA strands.
Joining (J) Segment: Joining segment is a tiny DNA segment that helps in joining the functional genes in order to produce functional genes on immunoglobulins.
Junctional Diversity: Junctional diversity happens in the place where V and J segments meet. This diversity reveals the variations in the DNA sequences produced by the incorrect linking of small segments of the gene during the V and J segments re-joining practice. Coding the hypervariable CR3 region in the antigen-combining pocket is the main function of junctional diversity.
Jumping Library: Jumping libraries, also known as jumping fragment libraries that help for the complete collection of genomic DNA fragments. Chromosome jumping helps in the production of these DNA fragments. These libraries help in 1) analyzing the regions of the genome in large size and 2) and to analyze the limitations in common cloning techniques. So, to keep it simple, the jumping library is a prominent tool or technique that helps in plotting and sequencing the chromosome cells in larger areas.
Juxta: Juxta is an organ present in the Lepidoptera males, located between two valvae. This organ supports another organ of insects that helps in reproduction. The word ‘Juxta’ is derived from the Latin word, Iuxta which means ‘alongside’. Juxta is otherwise helpful in representing the identical structure of it in flesh flies.
Jaw: The jaw is a facial structure that contains teeth, a movable lower jaw, and an immovable upper jaw. The lower jaw is mandible while the upper jaw is maxilla. All these parts of the frame structure of the face form the framework of the mouth in all vertebrates. The primary function of jaws is grinding, cutting, and managing food in the mouth.
Juice: Juice is a healthy drink from the processing of liquid content in fruits and vegetables. Fruit juices are healthy but when highly concentrated, it turns unhealthy as the sugars may cause obesity and overweight issues. Which eventually results in high blood pressure, diabetes, heart stroke, and other medical issues.
Joint: A joint is an area where two or more bones link to one another. These joints in the human body help to move the bones with the help of soft tissue known as cartilage. Cartilage covers the naked bone at their joints. In the human body, there are 206 bones in total. Hinge, Pivot, Saddle, Planar, condyloid, and ball-and-socket are the five main joints in the human body.
