Which of the following processes generates new genetic variation in a population?

Which of the following processes occurs in meiosis but NOT in mitosis?

A mutation in a single gene in mice leads to a wide range of effects, including changes in fur color, bone structure, and immune function. This phenomenon, where one gene influences multiple traits, is known as:

You have identified the mutation in a p53 gene responsible for an aggressive type of lung cancer. The mutation is highlighted in red and underlined in the DNA sequence data below.  What type of mutation is it? [answer1] What change does the mutation cause? [answer2] Normal p53 Sequence: 3′ – AATGCAAAACCATTGCCA – 5’Mutant p53 Sequence: 3′ – AATGCAAATCCATTGCCA – 5′

Red-green color blindness in humans is inherited as a recessive X-linked trait. The allele for normal vision is B, and the allele for colorblindness is b. A husband and wife have 2 sons and 2 daughters. One son and one daughter are color blind. What are the genotypes of the parents?

Each messenger RNA (mRNA) codon corresponds to…

Genetic engineers use Cas9 and restriction enzymes to cut DNA in specific locations. Cas9 and restriction enzymes are naturally found in ________ which use them to fight off viral infections.

During DNA replication, our cells use the enzyme helicase to “unzip” the two strands that comprise the DNA molecule. To make copies of specific DNA sequences in the lab, scientists use polymerase chain reaction (PCR).  PCR mimics DNA replication in some ways, but not in how the two strands are pulled apart. How are the two strands of DNA unzipped during PCR? 

The building blocks of DNA are nucleotides. There are four unique nucleotides found in DNA, adenine (A), cytosine (C), guanine (G), and thymine (T). What component of a nucleotide gives its unique characteristics and corresponds to its shortened name?

A tumor that has spread to many organs has entered the stage of _______.
