Answer A)
The gene would not be transcribed. This is because the gene transcribing machinery would not be activated if the promoter sequence is not recognized. Transcription will not start.
Answer B)
The gene would not be transcribed. This will result in no RNA polymerase being formed. Hence, transcription and translation will not occur.
Answer C)
The mRNA would contain intron sequences, which would be translated into extra amino acids in the protein. A non- functional protein would be made.
It is true that first time parents are usually concerned about red dots on their infant's face and neck. The nurse should tell these new parents it is quite normal for newborn's skin to have these red dots and these red dots are normally harmless and usually disappear after a few weeks.
Common rashes or red spots on newborn babies are believed to be due to exposure in the womb to maternal hormones. These new born rashes are believed to be normal and would normally disappear after a few weeks on their own.
Answer:
D. Most of the energy from photosynthesis flows out as heat
Explanation:
Energy flow is the amount of energy that moves through a food chain in a given ecosystem
Answer:
the alveoli are made of thin squamous (type I) alveolar cells which allows for the quick diffusion carbon dioxide and oxygen.
Explanation:
Diffusion of gases takes place between the alveolar cavity and the blood in the capillaries. Oxygen being more concentrated in the alveoli diffuses across the epithelium of the alveoli and the endothelium of the capillaries into the blood. The epithelial walls of the alveoli are moist and thin thus enhancing the diffusion.
Answer:
D
Explanation:
Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell's activities, while RNA converts that code into proteins to carry out cellular functions.
