Q: Answer the following question given this paragraph: Similar to chromosomal alteration mutations, deletion or insertion mutations add or remove genetic information. Small deletions or insertions in the DNA will alter the reading frame. Deletions remove one or more nucleotides from the DNA, whereas insertions add one or more nucleotides into the DNA. These mutations in the coding region of a gene may also alter the splicing of the mRNA, known as a splice site mutation . Mutations which alter the reading frame are known as frameshift mutations . Splice site mutations and frameshift mutations both can dramatically change the mRNA, altering the final protein product. Q: Deletions remove one or more what from the dna? Choices: - codons - exons - genes - nucleotides A:
A: nucleotides

Q: Answer the following question given this paragraph: Meiosis involves two cell divisions and produces four haploid cells. Q: What process involves two cell divisions and produces four haploid cells? Choices: - mutations - Mitosis - Klerokinesis - meiosis A:
A: meiosis

Q: Answer the following question given this paragraph: Clouds form when water vapor condenses around particles in the air. The particles are specks of matter, such as dust or smoke. Billions of these tiny water droplets come together to make up a cloud. If the air is very cold, ice crystals form instead of liquid water. Q: What forms when water vapor condenses around particles in the air? Choices: - wind - storms - humididty - clouds A:
A: clouds
