How Traits Change Part 1

What is the purpose of the proteins made from the DNA code?

• To express inherited traits and tell cells what to do and function

• To store genetic information

• To provide energy to cells

• To protect the cell from damage

What does DNA stand for?

• Deoxyribonucleic acid

• Ribonucleic acid

• Amino acid

• Nucleic acid

Which nitrogenous base pairs with Guanine in DNA?

• Cytosine

• Adenine

• Thymine

• Uracil

What are the three important parts of DNA?

• Double stranded, has deoxyribose sugar, and has thymine

• Single stranded, has ribose sugar, and has uracil

• Double stranded, has ribose sugar, and has uracil

• Single stranded, has deoxyribose sugar, and has thymine

What is the first step in protein synthesis?

• DNA unzips the specific gene section

• mRNA is created during transcription

• mRNA leaves the nucleus

• tRNA enters the ribosome

What is the main function of a gene?

• To store energy

• To synthesize proteins

• To transport oxygen

• To provide structural support

Where is the genetic material (DNA) found in a cell?

• Cytoplasm

• Ribosome

• Nucleus

• Cell membrane

What is a nucleotide composed of?

• Phosphate, sugar, and a nitrogen base

• Lipids, proteins, and carbohydrates

• Water, salt, and glucose

• Amino acids, enzymes, and vitamins

What structure does DNA form?

• Single strand

• Double helix

• Triple helix

• Quadruple strand

What is the role of tRNA in protein synthesis?

• It stores genetic information

• It brings amino acids to ribosomes based on codons

• It breaks down proteins

• It transports lipids
