Nucleic Acids and Protein synthesis

What is represented by the structure labeled 2?

• ribosome

• amino acid

• mRNA

• tRNA

How does tRNA help in the differentiation of

structures as an organism develops?

• tRNA creates the amino acid chain that will eventually code for

  the specific protein that makes up a specific organ.

• tRNA takes the DNA code to the ribosome so that the specific

  protein can be made that makes up a specific organ

• tRNA is stored in the nucleus and carries the genetic code to

  make all of the specific structures of the body

• tRNA packages the proteins and takes them out of the cell

The diagram represents the process of gene expression,

which demonstrates how a section of a chromosome becomes

an observable trait, such as the color of a flower. Which of the

following are true statements related to the process of gene

expression?

• Genes code for intricately folded proteins called

  polypeptides.

• Protein molecules carry the code for creating traits

  such as flower color.

• Chromosomes are made of larger units called genes

  which create observable characteristics.

• Genotypes represent an observable trait such as color

  and scent.

• DNA is divided up into smaller, functional units called

  "genes" which provide the instructions for creating a

  product.

Which mutation would change the greatest number of amino

acids in a protein?

• the substitution of a thymine nucleotide with a cytosine

  nucleotide near the beginning of a gene

• the addition of the nucleotides that make up an additional

  stop codon to the end of a gene

• the insertion of a thymine, a guanine, and an adenine

  nucleotide in that order at the start of a gene

• the deletion of a single adenine nucleotide in the middle

  of a gene

Select TWO correct answers.

• phosphate, a 5-carbon sugar, and a nitrogen base.

• Nucleic acids are made from repeating subunits

  called amino acids.

• Nucleic acids play a major role in the storage and

  expression of genetic information.

• Nucleic acids only include DNA.
