Explain mendel's experiment with peas on inheritence of characters considering only one visible contrasting character.

m_a_m_a [10]

➜ Mendel conducted breeding experiments with garden peas:

[i] He studied plants (pure) of a tall/short varities.

[ii] He crossed them and obtained F1 progeny.

[iii] He found that F1 progeny was all tall plants.

[iv] He selfed the (hybrid) plants if F1 progeny.

[v] He found that in F2 progeny there were tall as well as short plants.

[vi] The three quarter plants were tall and one quarter was short.

(or any other contrasting character may be taken).

Note: Here, F1 means First fillial generation and F2 means Second fillial generation.

<h2>T4 protein and T4 DNA</h2>

Explanation:

A bacteriophage is an infection that attacks bacteria. At the point when the tail strands identify an objective host the bacteriophage to the cell, injected its DNA, and utilizations the microscopic organisms' apparatus to reproduce.
T4 is a sort of bacteriophage that infects of E. coli.
The bacteriophage T4 capsid is a prolonged icosahedron, 120 nm long and 86 nm wide, and is worked with three essential proteins such as gp23*, which shapes the hexagonal capsid cross section, gp24*, which structures pentamers at eleven of the twelve vertices.
gp20, which frames the extraordinary dodecameric entry vertex through which DNA.
T4 DNA Ligase is ligation catalyst which utilized the parts of DNA by the catalyzing between compared 5'phosphate and 3' hydroxyl ends and phosphodiester bonds in the double stranded DNA utilizing ATP as a coenzyme.

An immunoglobulin (Ig) molecule, of any class, with regions symbolized as C or V, H or L , has a light chain made up of _______.

Nadusha1986 [10]

An immunoglobulin molecule of any class with regions symbolized as C or V, H or L, has a light chain made up of one C region and one V region.

The glycoproteins known as immunoglobulins (Ig), often known as antibodies, are created by plasma cells. A number of immunogens, including bacterial proteins, promote B cells' conversion to plasma cells. These cells, which make proteins, are involved in humoral immune reactions to bacteria, viruses, fungi, parasites, cellular antigens, chemicals, and synthetic compounds. Using a B-cell receptor, the immunogen or antigen adheres to the B cells' cell surface (BCR).

As a result, a signal is generated that directs the activation of transcription factors, leading to the manufacture of highly specific antibodies for the immunogen that initially activated the B cell. Furthermore, one B cell clone produces immunoglobulin (specificity). Two light chains and two heavy chains that alternate in a light-heavy-heavy-light pattern make up antibodies, also known as immunoglobulins. Therefore, choice A is the right response.
