Answer:
Estrogen levels days prior to ovulation
Explanation:
Estrogen is responsible for the reproductive system in women and high levels occur naturally during menstruation as compared to glucose levels in blood as the pancreas is constantly producing more insulin to lower the glucose in blood.
Answer:
False
Explanation:
In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.
There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.
Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
Answer:
Motor protein kinesin can "walk" along a microtubule while carrying vesicles and by changing its shape the kinesin.
Explanation:
Motor protein kinesin is an important microtubule based motor protein that is conserved among all eukaryotic organisms. Its movement along the microtubule is ATP powered. Most of the kinesins walk towards the plus end of the microtubule.
Due to its ability it is responsible for unidirectional transportation of cargos including membranous organelles and mRNA.
