Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in a tRNA
chubhunter [2.5K]

Answer:

Substitution

Explanation:

There are 3 types of mutations: deletions, insertions, and substitutions.

A deletion deletes one of the bases (AGTC), which can completely mess up the sequence and create a completely different protein.

An insertion inserts a new base into the strand, which can also completely mess up the sequence and create a completely different protein.

A substitution just changes one of the bases to a different base. This doesn't usually affect what protein is made, but when it does, it only changes one of the amino acids in the sequence, whereas the others change all of the amino acids in the sequence.

If the same protein is still created, then this person only experienced a substitution because it didn't affect the end result of the protein.

Answer:

Needs optimum environmental conditions.

Explanation:

Seedling, a flower and a vegetable needs suitable conditions for growth and development. All of the three stages of plant life cycle requires optimum water, fertilizers and light intensity in order to grow and develop at full speed. Seeds need a specific temperature in order to germinate. Most seeds germinate when the soil temperature is between 68 and 86 Fahrenheit. In the same way the plant also needs specific temperature for bearing flowers. All the stages requires optimum water in the soil for absorption.
