2. Many people believe that a mutation will always result in the formation of a deadly tumor, or the development of a major body defect.

Explain why this is incorrect.

. There are multiple types of mutations in DNA. mutations occur when a single base is changed to a different base pair. mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation. mutations are also considered frameshift mutations, and occur when one or more extra bases are added to a segment of DNA.

Explanation:

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
