Answer:
c. DNA binding to histones enables overall positive supercoiling without enzymes that underwind the DNA helix.
Explanation:
Plants roots display positive gravitropism which means they grow in the direction of gravity
Them the solution is hypertonic. This means that the water within the cell would exit it and go outside and the cell would shrink.
Answer:
Cis-acting sequence in bacteria that control transcription.
Explanation:
The proteins binds to Cis-acting sequences in transcription process of bacteria. This binding control the expression of one or more genes. These similar sequences are also found in eukaryotes.
The gene transfer assay helps in identifying these sequences in eukaryotes. Thus, Cis-acting sequence Controls the expression of one or more genes by serving as the binding site for regulatory proteins.
The statement above is TRUE.
Food such as red meat and butter contain saturated and trans fat which are considered to be unhealthy for the brain and for the heart also. A recent research study reported that, trans and saturated fats are associated with poor cognitive function and memory in women.
