Punnet squares are a useful tool for predicting what the offspring will look like when mating plants or animals. Reginald Crundall Punnett, a mathematician, came up with these in 1905, long after Mendel's experiments. Let's take a look at how Punnet squares work using the yellow and green peas example from im not sure about the tree by three thing but maybe this will help :)
Absolute maximum is 115.7 years of age
The correct characteristic of the Ascomycota is definitely C. Sac formation, because they produce <span>microscopic spores inside sacs. I am pretty sure that this answer will help you. Regards!</span>
Answers:
A(n) operon is a stretch of DNA consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway.
The Gene of an operon is arranged sequentially after the promoter
A(n) promoter is a specific nucleotide sequence in DNA that binds RNA polymerase, positioning it to start transcribing RNA at the appropriate place.
A(n) regulatory gene codes for a protein, such as a repressor, that controls the transcription of another gene or group of genes.
Regulatory proteins bind to the operator to control expression of the operon.
A(n) repressor is a protein that inhibits gene transcription. In prokaryotes, this protein binds to the DNA in or near the promoter.
A(n) inducer is a specific small molecule that binds to a bacterial regulatory protein and changes its shape so that it cannot bind to an operator, thus switching an operon on.
