Answer:
Watson and Crick were able to develop a more accurate molecular structure because they had access to x-ray crystallography! Pauling didn't actually failed, he just did't have the same means!
Explanation:
By the way, is now known that the real discovery of DNA molecule was made by Rosalind Franklin. Any doubts you can send me a message!
Answer:
In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).
Explanation:
Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.
From the sequence:
AUGGUGCAUGUC
Four codons are obtained, each of which encodes a different amino acid:
<em>Codons: AUG-GUG-CAU-GUC</em>
<em>Amino acids: Met - Val - His - Val</em>
<em>Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.</em>

one of the most important rain forest predators, attacking a wide range of different primates, is the monkey-eating eagle. we know this because all forest primates have an identical alarm call that means, essentially, "Eagle!"
<h3>What are primates?</h3>
Primates are those forest animals that has highly developed brain and backbone.
Some of them are predators while others are source of food for predators known as preys.
Example of such predators are the monkey eating eagles which are capable of hunting monkeys as their preys.

Answer:
The history of the human evolution can be studied by the fossil and DNA evidence. The similarities and advancement in certain characters has revealed the human evolution.
Different evidences like change in the diet, locomotion, brain size, walking ability as compared with the present species and species appeared 6 million years ago. The human genetics evidence and different paintings explain the culture of earlier homo species.The H. sapiens species has highly advance character that help them to survive than any other hominid species. The neanderthals extinction might occur due to their aggressive behavior, low social ability and their large cranial size.
