Explanation:
Answer:
B. Humans and chimpanzees share a relatively recent common ancestor.
Explanation:
Both the humans and Chimpanzees are the primates that are they belong to the same group called hominids and genus called Homo.
When the DNA sequences of the Chimpanzees and the Humans are sequenced and compared than they showed that 98% of the genome is similar.
In the given question, the single strands of the humans and the chimpanzees base-paired which showed that 98% of the nucleotide sequence is the same. The most possible reason for this similarity is that they both were evolved from the common ancestors and they diverged recently in the past.
Thus, Option-B is correct.
Answer:
The correct option is a (True).

Carl Woese<span>, </span>Francis Crick<span>, and </span>Leslie Orgel<span> were the first to suggest that RNA could act as a catalyst in 1967. This idea was based upon the discovery that RNA can form complex </span><span>secondary structures. </span>Nick et al. (2000) have reported that ribozyme play a key role in catalyzing tRNA amino-acylation.
