Harm to animals, washes up on beaches
The answer is ‘in the dermal papillae of hairless skin’. Dermal papillae is the layer of the skin (upper dermis) with numerous blood vessels and nerves that serve the epidermis of the skin. Tactile corpuscles (nerves) are mostly found in this region and occur mostly in hairless thick skin such as in finger and toe tips.
Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
The answer to this is false
