Answer:
This makes it a heterozygous allele and the dominant allele with be expressed.
For example:
T is for tall and t is for short
The heterozygous allele is Tt, which makes the allele "heterozygous tall"
Answer:
Results in a hairpin loop structure in RNA, AND results in the polymerase falling off the DNA template.
Explanation:
As the RNA polymerase arrives at the terminator site, it pauses. The termination of RNA transcription occurs when an RNA transcript with a self-complementary sequence is formed leading to the formation of the hairpin structure. The hairpin structure has 15-20 nucleotides.
The hairpin structure of RNA weakens A=U base pairs in RNA-DNA hybrid and/or weakens the interaction between RNA and RNA polymerase. The overall effect is the dissociation of RNA polymerase from the complex and termination of the transcription.
Yes it absolutely makes sense and it is correct. Although there are many more definitions of a gene out there but this one is not wrong.
