Answer:

The correct answer would  be option C.

Ribosomal RNA (rRNA) is used as molecular clock due to many factors such as:

It has very slow mutation rate (around 1 million years) due to which it remains highly conserved in all the organisms. The degree of mutations present in rRNAs of two organisms can be directly linked to the time they were evolved in past.

In addition, it has essential biological function due to which it can be found in almost all the organisms.

In which of the following ways is DNA replication different from DNA transcription?
earnstyle [38]

Answer:

Thymine is used in replication while uracil is used in transcription.

Explanation:

<em>New cells can only be created after transcription has taken place. Replication results in mRNA strands while transcription creates new DNA. Transcription happens outside the nucleus and replication happens inside the nucleus. Thymine is used in replication while uracil is used in transcription.</em>

DNA replication is a process whereby DNA makes a copy of itself while DNA transcription is a process whereby a messenger RNA is synthesized from a DNA strand.

Both processes involve the building-up of nucleotides or purine.pyrimidine bases. Replication involves building up of cytosine, guanines, adenine, and thymine bases while in transcription, the thymine base is replaced by uracil base.

Hence, the correct answer is that <u>Thymine is used in replication while uracil is used in transcription.</u>
