QuestionAnswer
The transfer of genes from parents to their offspring is known as heredity
Hereditary traits are transmitted from generation to generation by means of specific sequences of bases in DNA in reproductive cells
In all organisms,the coded instructions for specifying the characteristics of the organism are directly determined by the arrangement of the four types of molecular bases in the genes
A certain protein is found in mitochondria, chloroplasts, and bacteria. This provides evidence that plants and bacteria have some similar DNA base sequences
Genes involved in the production of abnormal red blood cells have an abnormal sequence of bases
Which statement best describes the relationship between cells, DNA and proteins? Cells contain DNA that controls the production of proteins
Three structures are represented in the diagram below...(PHOTO OF PROTEIN cell DNA) What is the relationship between these three structures? DNA controls the production of protein in the cell.
The diagram below represents a protion of an organic molecule (PHOTO TCGA) This molecule controls cellular activity by directing the synthesis of Proteins
The diagram below represents an incomplete section of a DNA molecule. The boxes represent unidentified bases. What will be the total number of bases represented by the letter A (both inside and outside the boxes) when the boxes are completely filled in? 3
One disadvantage of a genetic mutation in a human skin cell is that it may result in the production of a defective protein
A characteristic of a DNA molecule that is NOT characteristic of a protein molecule is that the DNA molecule can replicate itself
Which nuclear process is represented below? DNA molecule untwists-2 strands of DNA separate-Molecular bases pair up-2 identical DNA molecules are produced replication
The diagram below shows some of the steps in protein synthesis. (PHOTO) The section of DNA being used to make the strand of mRNA is known as a gene
