There was no life on Earth for the first billion years because the atmosphere was not suitable for life. Earth's first atmosphere had lots of water vapor but had almost no oxygen. Later, frequent volcanic eruptions put several different gases into the air.
Answer:
A single nucleotide changes in CCG which will result in missense mutation can be many possibilities.
Explanation:
Missense mutations
CCG codes for Proline amino acid
• Mutation in first nucleotide codes for
UCG specifically encodes Serine
ACG specifically encodes Threonine
GCG specifically encodes Alanine
Missense mutation
• Mutation in second nucleotide specify for coding
CUG specifically encodes Leucine
CAG specifically encodes Glutamine
CGG specifically encodes Arginine
• Mutation in Third Nucleotide will not result in missense mutation because any point mutation in third nucleotide of codon will encode same amino acid i.e Proline.
Answer:
In the waste process
Explanation:
When plants photosynthesize, they take in carbon dioxide, and the waste is oxygen!
