C. Is incorrect because some cells don’t survive for more than half a century
Answer:
false
Explanation:
These different faces are called phases and they are the result of the way the Sun lights the Moon's surface as the Moon orbits Earth. The Moon can only be seen as a result of the Sun's light reflecting off it. It does not produce any light of its own.
Answer:
1. Mutation
2. Gene flow
Explanation:
New traits can be made when there is an error in gene replication, called a mutation. The mutation will give the offspring different genes that might be harmful or beneficial to the organism.
Gene flow happens when any organisms from other places immigrate into the population. If these organisms can reproduce with the local organisms, it will introduce new traits that was not originally come from the population.
Answer:
d) binding of the anticodon to the codon and the attachment of amino acids to tRNAs.
Explanation:
A transfer RNA (tRNA) is one of the three types of RNA molecules whose job is to match an mRNA codon( a sequence of three DNA or RNA nucleotides that corresponds to a specific amino acid) with the amino acid it codes for.
Each tRNA contains a set of three nucleotides called an anticodon which corresponds to the amino acid encoded by a codon of an mRNA. The amino acid encoded by the codon is also attached to the tRNA molecule. This ensures specificity and accuracy during translation.
Therefore, during the translation of mRNA into the primary structure of a polypeptide, accuracy depends on specificity in the binding of anticodon and attachment of amino acids to tRNA.
