​Semi-conservative

• ​Semi- conservative replication-

• ​Each DNA molecule is "half old" and "half new"

Multiple Choice

Whats the process by which DNA copies itself, making new cells?

• Transcription

• Replication

• Duplication

• Translation

Multiple Choice

IS THIS DNA OR RNA?

• DNA- DOUBLE HELIX

• RNA- SINGLE STRANDED

• BOTH, IN THE NUCLEUS OF THE CELL

• RNA- DOUBLE STANDED

Multiple Choice

WHAT IS TRUE ABOUT RNA?

• Single stranded, contains Uracil, never found in nucleus

• Contains Cytosine, Guanine, Adenine and Uracil.

• Contains Cytosine, Guanine, Adenine and Thymine

• Replication takes place in RNA.

Multiple Choice

What is RNA's function?

• To make more RNA

• To create a mutation, to duplicate genes

• To make chromosomes

• To use information from DNA for protein synthesis

Yay! R-T-T

​1) Replication- DNA copies itself into new cells

​

2)Transcription-(copy) DNA is transcribed into mRNA

​

​3)Translation- mRNA leaves and travels to the ribosome where it is read in groups of 3, called codons.

​

-Each codon codes for one amino acid.

​

​mRNA- carry the DNA's genetic code outside of the cell. The complimentary copy of DNA

​tRNA- Transfers the correct amino acid to the ribosome based on the codon sequence of the mRNA.

rRNA- Makes up the ribosome
