What is another name for lagging strands?
Okazaki fragments
Which of the following are actually cell fragments and not whole cells?
Platelets
What is the example of isolobal?
[Mn(CO)5],ch3,cl and H derived from octahedral fragments are examples of isolobal.
What is a DNA size standard and why is it used in gel electrophoresis?
You may be referring to the DNA ladder used in gel electrophoresis. The ladder is a collection of DNA fragments of known size (e.g. 100, 500, 1000, 2000, 5000, 10000 base pairs) so that if it is loaded beside the samples, it can offer a 'ruler' that can be used to determine the size of the fragments in the samples.
Why is gel electrophoresis important?
To separate and analyze DNA fragments and protein fragments by weight. If you have digested some bacterial DNA, for instance, then you can tell by running the fragmented DNA in the gel whether you have digested the correct base length.
What are limestones composed of?
Limestones are predominantly composed of the mineral calcite, which is a form of calcium carbonate. They often also contain small amounts of other minerals and impurities, which can affect their color and texture. Limestones are formed through the accumulation of skeletal fragments of marine organisms like coral, shellfish, and algae.
What is the chemistry of limestone?
The limestone consists mainly of calcium carbonate: CaCO3 ,Calcite. Like most other sedimentary rocks, limestones are composed of grains, however, around 80-90% of limestone grains are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. Some limestones do not consist of grains at all and are formed completely by the chemical precipitation of calcite or aragonite. (i.e. travertine.)
What is present in limestone?
Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. Many limestones are composed from skeletal fragments of marine organisms such as coral or foraminifera.
Limestones are only formed from the remains of once-living creatures?
Limestones can be formed from the calcium carbonate deposits of both living and non-living sources. While some limestones are indeed formed from the remains of marine organisms like corals and shellfish, others can be formed from precipitation of calcium carbonate from seawater or from the transformation of existing carbonate rocks under high pressure and temperature.
What type of rock is carboniferous limestone?
Carboniferous limestone is a type of sedimentary rock that is formed from the accumulation of skeletal fragments of marine organisms such as corals and mollusks. It is typically composed of calcium carbonate and is known for its durability and suitability for building materials like aggregates and cement.
How can bone fragments be broken down by the body?
Bone fragments can be broken down by specialized cells called osteoclasts. These cells secrete enzymes and acids that break down the mineralized matrix of bone, allowing the fragments to be reabsorbed into the body for recycling and potential use in bone remodeling or repair.
Is limestone made of animal skin?
"Limestones are composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as Coral or Foraminifera."
What is an example of a sedimentary rock that is biochemical (organic)?
Limestone and chalk are formed from organic material Limestone - Clastic shell fragments Chalk - Microscopic shells of calicum carbonate plates formed by single celled algaes Chert - Microscopic siliceous organisms, recrystallized silica
Is conglomerate a biochemical?
No, a conglomerate is not a biochemical. A conglomerate is a geological term referring to a rock made up of different kinds of minerals and rock fragments. Biochemicals, on the other hand, are chemicals produced by living organisms.
Which is a biochemical rock that contains fossils?
Limestone is a biochemical rock that can contain fossils. It is formed from the accumulation of calcite or aragonite shells or skeletal fragments of organisms such as corals, foraminifera, and mollusks. Over time, these remains can be compressed and preserved in the rock.
Mountain rocks are often broken down through?
Weathering processes such as freeze-thaw cycles, chemical weathering, and biological weathering. These processes break down the rocks into smaller pieces, eventually leading to the formation of sediment.
What name is given to the rock that all houses are built with in Bath?
The stone is an Oolitic Limestone comprising granular fragments of calcium carbonate. Commonly known as Bath Stone.
