What purpose does pollen serve in fertilization

1. What conclusions can you draw about the results of your first cross between a homozygous red bull (RR) and a heterozygous re

rusak2 [61]

1. The conclusion that can be made about the results of your first cross between a homozygous red bull (RR) and a heterozygous red cow (Rr) is shown below :
You supposed to make a punnet square, so (picture)
Than you will get that the first generation will be 50% homozygous dominant
and 50% heterozygous which lead us to conclusion :
Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).

2. Conclusion about the results of your second cross between a heterozygous red bull (Rr) and a heterozygous red cow (Rr) is shown in the second picture. And you can see that in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).

3. Conclusion about the results of your third cross between a homozygous white bull (rr) and a homozygous white cow (rr) are shown in the third picture. In this case you can see the result of 100% (homozygous recessive).

Describe what RNA splicing is and how it explains that the

Elena L [17]

Answer:

RNA splicing is the intron removal and exon binding in the mRNA before leaving the nucleus.

Explanation:

Alternative splicing of identical RNA transcripts into different cell types can produce different mature mRNA molecules that translate into different polypeptides.

The genetic information encoded in the AND is transcribed to a copy of RNA (primary transcript). This copy is then modified with the addition of the 5 ’cap (CAP) and the poly-A tail, the excision of the introns and the union of the exons (splicing). The mature mRNA then goes to the cytoplasm, where it is translated into proteins.
