Amistake in dna replication, in which the wrong base is placed in the growing dna strand, can have profound effects on the descendents of any cells that carry the mistake. in the following strand, the a has been changed to a g. draw the dna molecules that result from replication of the altered strands.

DNA replication is the process in which the DNA is copied and it occurs during synthesis phase of the eukaryotic cell cycle. It begins with an enzyme breaking the bonds between complementary bases in DNA which exposes the bases inside  the molecules so they can be read by another enzyme and used to build two new DNA strands with complementary bases.

Explanation:

The original strand is: TAGCGTT

                                      ATCGCAA

The Mutated strand is: TGGCGTT

                                       ATCGCAA

The replicated strand is: GAATCAC

                                          CTTAGTG

the real answer is b. scintillation counter

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
