Answer:
Deletion mutation usually takes place due to the errors in the process of DNA replication . DNA polymerase slips off on the template strand due to which that part of the DNA is not coded in the daughter strand.
It can skip from one nucleotide (point mutation) to an entire gene. Point deletion can result in frame-shift mutation if it takes place in the beginning or middle of the gene. However, if it takes place at the end of the gene then it may cause no harm.
For example, let us assume the original sequence of DNA as ATG-AGT-CGT-ATA-TAA. It will result in the formation of methionine, serine, arginine, isoleucine, and STOP codon.
Point deletion at the end of the gene results in ATG-AGC-GTA-TAT-AA sequence. Now it will code for methionine, serine, valine, and tyrosine as AA will not code for anything. Hence, the sequence of the protein remains the same.
Hence, if deletion mutation takes place at the last or stop codon of the gene then it will cause no harm or change in the protein sequence. However, if it takes place before that then it may result in frame-shift mutation and thus a mutated protein.
Evidence would the fossils they left in the grounds they found.
Answer:
Yes...
Explanation:
Hypothesis is a proposed explanation made by reasoning without assuming what the truth is..
From the question;
Formal hypothesis: Eating chocolate may cause pimples because chocolate will result to an increment in the amount of oil in the skin and this will result in pimples.
2. Salt in water can affect plants growth.
Formal hypothesis: plants grow beside the ocean will grow slower because the salt present in the soil will destroy the root of plants.
