Answer: <u>D. Thymine is used in replication while uracil is used in transcription.</u>
Explanation:
Genetic information is stored in double-helixes of DNA molecules (Doxyribonuclease). In replication, two daughter strands of DNA are copied from the parent strand, while in replication, instructions stored within DNA are copied into a different form, called mRNA or messenger RNA.
Nucleotides are monomers comprising DNA, a nucleic acid that along with RNA, a ribose sugar-containing nucleotide, acts as a storage molecule to encode proteins. 5-carbon deoxyribose or ribose sugar, phosphate and one of four nitrogen bases are found in nucleotides:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T).
Uracil (U) found in RNA
While <em>both contain four nucleotide bases, </em> in RNA, uracil replaces thymine... The DNA nucleotides are involved in replication while RNA nucleotides drive transcription,
Before puberty, children do have an estrogen level in their body. This is only truly noticeable around the time of puberty. It's always there, but not hyperactive until puberty.
