A codon<span> is a three-base sequence (three nitrogen bases in a row) on mRNA. It calls for a specific amino acid to be brought to the growing polypeptide. An </span>anticodon<span> is a three-base sequence on tRNA. It matches the </span>codon<span>.</span>
<span>Isometric muscular contractions do not change the length of the muscle they are responsible for movement. Isotonic muscular contractions will lengthen or shorten the muscle. Concentric contractions shorten the muscle. Eccentric contractions lengthen the muscle.</span>
Explanation:
Percentage w/v means that weight of solute present in 100 ml of a solution. Hence, 15% w/v means that 15 gram of solute per 100 ml of solution.
Hence, for 2 L (or 2000 mL) preparation the amount of mass will be calculated as follows.
= 300 g
Thus, we can conclude that weight of Tris-HCL required is 300 g.
Answer:
Basic characteristics of Sponges:
Sponges belong to phylum porifera. They are simple multi-cellular aquatic animals. They have pores in their body thats why they look like sponge we use in kitchen. These pores are known as ostia. The body cavity is known as spongocoel, which open to out side through large pore known as osculum. Their body is composed of two layers, choanocyte and pinacocyte. Choanocytes are flagellated cells having spikes which help in movement of water into body and aid in capturing of food particles. The skeleton is made up of calcium carbonate or silica. A jelly like substance called as mesoglea is present between pinacocyte and choanoderm.
<span>General characteristics of Archeocyathans:
</span> The term archeocyathans is a Greek word for "ancient cup". They have a single common ancestor and became one of the planet first reef animals. S<span>pecies of archeocyathans is divided into two classes, six orders, 12 suborders, 120 families and nearly 300 genera. They are associated with carbonate sedimentation.They generally lived in shallow water with photic zone. Their fossils often co-occured with fossils of cyanobacteria. </span><span>These are marine organisms whose fossils record dated back to late Precambrian and early Cambrian period. They are most closely resemble to calcareous sponges. Their structure s are conical or tubular in shape and superficially resembles horn reefs. They have world wide distribution and found in Australia, Antartica, Spain, Cubec, New york and California,</span>
Answer:
The scheme of the tautomers of cytosine, guanine and thymine are found in the attached file
Explanation:
The primary imine-amine tautomerism occurs in heterocyclic compounds where hydrogen may be forming the amino group (primary amine form) or migrate to adjacent nitrogen (imine form), may occur in some nitrogenous bases such as cytosine. Thymine shows double lactam-lactymal tautomy (where hydrogen migrates from the nitrogen atom to the oxygen atom of the heterocycle oxo group (lactam form) and vice versa (lactose form)), and guanine and cytosine can both.
