The hepatitis B and the human papillomavirus (HPV) vaccines are made this way. The vaccine is composed of a protein that resides on the surface of the virus. This strategy can be used when an immune response to one part of the virus (or bacteria) is responsible for protection against disease.Jun 28, 2016

During the Human Genome Project, scientists created a gene map showing the relative location of each known gene on every human c
Arlecino [84]

Answer:

Approximately 20,500 genes

Explanation:

The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.

A dihybrid cross is performed between plants that differ in two Mendelian traits: Stem length (T or t) and flower coloration (R
Dahasolnce [82]

Answer:

A. 3/16

Explanation:

The four possible outcomes for Stem length are:

Tt, tT, TT and tt.

The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.

The four possible outcomes for flower coloration are:

Rr, rR, RR and rr.

The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.

Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

\frac{3}{4}*\frac{1}{4}=\frac{3}{16}

Therefore, the answer is A. 3/16

If a double foul occurs during a down in which time expires, the period is ended
Zina [86]
This statement is false.

Double fouls are when two players on opposing teams commit a foul, which makes the fouls of the players "cancel out" and ball possession does not change. However, personal fouls are still charged on both of the offending players.
