genetic mutations refer to alterations in the sequence of ____ that make up an organism’s dna.
silent mutations occur when the altered codon still codes for the same ____ due to the redundancy of the genetic code.
point mutations involve changes in a single ____ within the dna sequence.
frameshift mutations occur when the insertion or deletion of nucleotides alters the ____ of the genetic code.
____ changes due to mutations can range from physical characteristics to susceptibility to diseases.
ultraviolet (uv) radiation from the sun is known to cause mutations in ____ when exposed excessively.
____ syndrome is caused by a deletion in a small segment of chromosome 22.

Question

Accepted Answer

### 1. First blank (Genetic mutations refer to alterations in the sequence of ____ that make up an organism’s DNA)
# Brief Explanations:
DNA is made up of nucleotides (which consist of a sugar, phosphate, and nitrogenous base). Genetic mutations are changes in the DNA sequence, so the missing term is nucleotides.
# Answer:
nucleotides

### 2. Second blank (Silent mutations occur when the altered codon still codes for the same ____ due to the redundancy of the genetic code)
# Brief Explanations:
The genetic code is redundant, meaning multiple codons can code for the same amino acid. In silent mutations, the change in codon does not change the amino acid it codes for. So the term is amino acid.
# Answer:
amino acid

### 3. Third blank (Point mutations involve changes in a single ____ within the DNA sequence)
# Brief Explanations:
Point mutations are mutations that affect a single nucleotide (base) in the DNA sequence, like a substitution, insertion, or deletion of one nucleotide. So the term is nucleotide (or base).
# Answer:
nucleotide (or base)

### 4. Fourth blank (Frameshift mutations occur when the insertion or deletion of nucleotides alters the ____ of the genetic code)
# Brief Explanations:
Frameshift mutations happen when nucleotides are inserted or deleted (not in multiples of three), which shifts the reading frame of the genetic code. The reading frame determines how codons are read during translation. So the term is reading frame.
# Answer:
reading frame

### 5. Fifth blank (____ changes due to mutations can range from physical characteristics to susceptibility to diseases)
# Brief Explanations:
Mutations can lead to changes in an organism's phenotype, which includes physical characteristics (like eye color) and physiological traits (like disease susceptibility). Phenotype is the observable set of traits of an organism. So the term is Phenotypic (or Phenotype).
# Answer:
Phenotypic (or Phenotype)

### 6. Sixth blank (Ultraviolet (UV) radiation from the sun is known to cause mutations in ____ when exposed excessively)
# Brief Explanations:
UV radiation from the sun is a mutagen that can cause mutations in the DNA of skin cells (since skin is exposed to the sun). So the term is DNA (specifically in skin cells, but the general term is DNA).
# Answer:
DNA (or skin cells' DNA)

### 7. Seventh blank (____ syndrome is caused by a deletion in a small segment of chromosome 22)
# Brief Explanations:
DiGeorge syndrome (or 22q11.2 deletion syndrome) is caused by a deletion in a small segment of chromosome 22. So the term is DiGeorge (or 22q11.2 deletion).
# Answer:
DiGeorge (or 22q11.2 deletion)
