Type of nitrogenous base with a double ring found in DNA and RNA:
svet-max [94.6K]

Answer:

The correct answer will be option-B (purine).

Explanation:

Nucleic acid structure is made up of monomer unit called nucleotide. Each nucleotide is composed of a five-carbon sugar, a phosphate group and five types of nitrogenous bases.

The nitrogenous bases are categorized in two forms the purines (adenine and guanine ) and the pyrimidines (cytosine, thymine and uracil). The "purines" contain double rings in their structure due to which they appear larger in size than pyrimidines which are made up of single rings.

Thus, Option-B is the correct answer.

Can someone please help me with this ap biology problem! I would really appreciate it:)
strojnjashka [21]

Answer:

D - the production of a specific mRNA will increase as a result of the binding of the hormone receptor complex to the DNA

Explanation:

We are told that the hormone binds a receptor and then enters the cell, binding to the DNA and promoting transcription of a specific gene.

Transcription is the process whereby mRNA molecules are synthesised from a DNA sequence, which are then translated into specific process. D is correct, as the gene the hormone binds to will increase in transcription, producing a specific mRNA.

A, B and C are much more general processes, not linked to the actions of a hormone on a specific gene.
