Answer:
Once a stop codon is recognized the so formed protein molecule will bind to one molecule of water in place of tRNA.
Explanation:
During the termination phase of translation when the ribosome recognizes any one of the 3 stop codons such as UAA,UAG and UGA at that time the polypeptide that is formed will get no tRNA to bind.
As a result instead of tRNA a water molecule binds with the growing polypeptide thus tRNA molecule get detached from the polypeptide,the polypeptide is released from the translation machinery by the activity of various protein called release factors.
Then the mRNA and two subunits of ribosome are also released from the translation machinery.
<span>New tree species discovered with cone-like features and have seeds as its covering are called pine trees. These pine trees have pine cones which is their reproductive structure. These pine cones are seeds exposed outside the trees. The pine cones belong to the plant group called gymnosperms.</span>
Answer:
Because the F1 plants all had a lowercase a/short plant allele, there was a 25% chance that two plants would contribute it to their offspring and they both did sometimes to make a aa offpsring.
Explanation:
All the F1 plants were heterozygous, so when they were crossed, the resulting genotypic ratio was 1 AA : 2 Aa : 1 aa. As you can see, this is the first time since the parent generation that there is a aa genotype and short plant phenotype, so that's why short plants reappeared.
1) As blood groups A and B are equally dominant so the individual will express both characteristics in the phenotype.
Notice how in all the 3 other examples the organism is only expensive 1 version (allele) of each gene. For example the mouse with brown fur may have 2 brown fur alleles (and so would have to express this characteristic even if it was recessive) but it could have 1 allele which is less dominant than the brown, in which case brown would be expressed. In this case the alleles were not co-dominant.
