Purple color is expressed in 3 out of the four because the law of dominance states that only one dominant gene needs to be present to express the trait. But there is one homozygous recessive that would be yellow because the genotype has two recessive genes.
Example: AA or Aa would be dominant because the capital letter represents the dominant gene
A wisdom teeth are vestigial third molars that human ancestors used to help grinding down plant tissue. The common postulation is that the skull of human ancestor had larger jaw with more teeth, which where possibly used to help chew down foliage to compensate for a lack of ability to efficiency digest the cellulose that make up a plant cell wall.
Answer:
C. Using the scientific method
Answer:
The correct answer is - B. Identification and binding of RNAP onto the promoter sequence.
Explanation:
Bacterial RNA polymerases have subunits known as Sigma factors responsible for the identification and specificity of promoter binding of RNAP and regulate the efficiency of RNA synthesis during transcription is initiated.
These bacteria producing the nonfunctional subunits of RNA polymerase or sigma factor will be unable to identify and tightly bind to promoter elements that are RNAP.
