Summary Introduction

To review:

The evidence that suggests that RNA (ribonucleic acid)molecules may have functioned as molecular replicators in early protocells.

Introduction:

Protocells are the first formed cells. RNA is a nucleic acid and is a major constituent of biological components essential for all forms of life. It contains information for protein coding. Many viruses have RNA as their genetic material.

In 40 words or fewer, explain why we think that RNA, and not DNA, was the hereditary material in the first protocell.
What is the purpose of a molecular clock?
select the correct options: A) For organisms that diverged  >74 mya, ignore 3rd base positions within codons because they will offer little phylogenetic information for organisms. B) use different parts ofthe genome to estimate different parts of a phylogeny C) Use only 1st base positions within codons because they increase rapidly at first, then level off as result of single subsitituions at the same sites D) Use slowly evolvong sites in the squecne, such as 2nd base positions within codonsfor analyzing the oldest relationships among organisms.
