What type of immunity provides lifetime immunity for the body against a specific pathogen?
Tems11 [23]


The type of immunity that provides lifetime immunity for the body against a specific pathogen is called  acquired immunity.  It is also referred to as adaptive or specific immunity.

Acquired  immunity is not present at  birth. it is learned. As a person's immune system encounters foreign substances (antigens) the components of acquired immunity learn the best way to attack each antigen and begin to develop a memory for that antigen. Acquired immunity is also called specific immunity because it tailors its attack to a specific antigen previously encountered. Its uniqueness lies in its ability to learn, adapt and remember.

Acquired immunity takes time to develop after first exposure to a new antigen. However afterward, the antigen is remembered, and subsequent responses to that antigen are quicker and more effective than those that occurred after first exposure. Memory of a particular antigen is kept by the B and T lymphocytes.

How does Earth's mass affect life on the planet?​
Galina-37 [17]

Answer:

Typically, the more massive the planet, the more massive the atmosphere it can acquire and maintain. This is important because the mass of a planet's atmosphere will directly influence its climate. The location of the “habitable zone” around a star will therefore be a function of the mass of the planet in question.

Examine the following two DNA template sequences. Sequence 1: TACGCTACGATCGTA Sequence 2: TACGCTACTATCGTA If both of these seque
makvit [3.9K]
<h2>Sequence code </h2>

Explanation:

DNA template (non coding strand) is always synthesized from 3'-5' direction and the complementary strand (coding strand) will be synthesized from 5'-3' direction; mRNA synthesized will be from 5'-3' direction and will have the same sequence as coding strand(only in place of T, U will be present)

Sequence 1: 3' TACGCTACGATCGTA 5'

Coding strand 1 : 5' ATGCGATGCTAGCAT 3'

mRNA 1: 5' AUGCGAUGCUAGCAU 3'

AUG codes for methionine(Met); CGA codes for alanine(Ala); UGC codes for threonine(Thr); UAG codes for isoleucine(Iso); CAU codes for valine(Val)

so protein 1 will be:

Met-Ala-Thr-Iso-Val

Sequence 2: 3' TACGCTACTATCGTA 5'

Coding strand 2: 5' ATGCGATGATAGCAT 3'

mRNA 2; 5' AUGCGAUGAUAGCAU 3'

AUG codes for methionine(Met); CGA codes for alanine(Ala); UGA codes for threonine(Thr); UAG codes for isoleucine(Iso); CAU codes for valine(Val)

so protein 2 will be:

Met-Ala-Thr-Iso-Val

Both the protein sequence comes out to be same hence function of protein 2 will be same as that of  protein 1
