A eukaryotic gene contains 14 exons. Most of the transcripts from this gene contain all 14 exons, but some contain only 11 exons
WARRIOR [948]

Answer:

D. Alternative splicing is the mechanism that produce complexity in the genes by splicing some of the protein coding part (exons) of a genes

Explanation:

There are certain splicing enhancers sites present in Exons which facilitiates the binding of RNA binding protein specifically SR protein family rich in Serine and Arginine residues. This SR protein will help in splicing of exons.

The significance of this type of mechanism is the ability of a cell to produce an isoform of protein which have retain their function.

This mechanism also help is diversity or in short in evolution.

nexus9112 [7]

Answer:

The probability of getting a dwarf and pink female is 1/2

Explanation:

In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele where coats are normally brownish.

A dwarf female from a pure line will have Xd Xd where d represent the  recessive trait and the female is also brownish (pp).

A pink male from a pure line will be XPY where P represent the dominant allele but not a dwarf (D).

            Xd             Xd                            Xp          Xp

XD       XDXd        XDXd             XP    XPXp     XPXp    F1 generation

Y           XdY           XdY                Y     XpY        XpY

P        XDXd   x    XdY                        XPXp    x    XpY

           XD         Xd                               XP              Xp

Xd     XDXd    <u>XdXd</u>                  Xp    <u>XPXp</u>         XpXp         F2 generation

Y        XDY        XdY                   Y       XPY          XpY

The probability of getting a dwarf and pink female is 1/2

Please... I need help!!!
Gwar [14]

Answer: One type of map uses the cytogenetic location to describe a gene’s position. The cytogenetic location is based on a distinctive pattern of bands created when chromosomes are stained with certain chemicals. Another type of map uses the molecular location, a precise description of a gene's position on a chromosome. The molecular location is based on the sequence of DNA building blocks (base pairs) that make up the chromosome. Buttt I don’t know if this is the answer your looking for. But I hope this helps in a way.
