What is DNA? |
Each side of the DNA ladder is made up of sugar-phosphate molecules, and the rungs of the ladder are made up of nitrogenous bases. |
|
|
What is DNA? |
When DNA is copied, the new DNA has bases that are identical to those of the original DNA. |
|
|
DNA Synthesis |
Two sides unwind and separate; a complementary strand is formed for each, and the resulting double-stranded DNA has one original strand and one new strand. |
|
|
Nitrogenous base pairs are specific |
adenine-thymine and guanine-cytosine |
|
|
Where is DNA? |
DNA is identical in every cell. The only difference is how it directs the cell to do a specific job. |
|
|
DNA |
is double stranded, contains deoxyribose,letter bases are A,C,T,G, and DNA is found in the nucleus. |
|
|
RNA |
is single stranded, contains ribose, made upof base pairs A,C,U,G, and can be found in nucleus or in cytoplasm |
|
|
Genes |
o The instructions for making a specific proteinare found in _____ in the cell nucleus. Proteins are made on ribosomes in the cytoplasm.o There are three main kinds of RNA—mRNA, rRNA,and tRNA.r |
|
|
· Mutations |
Messenger RNA (mRNA) caries codes from DNA outof the nucleus and into the cytoplasm to the ribosomeo Ribosomal RNA (rRNA) makes up part of theribosomeso Transfer RNA (tRNA) pulls amino acids to theribosome for the creation of proteins. Groups of three amino acids at a time are thebuilding blocks of proteins. If DNA is not copied exactly, the resulting_______ may cause proteins to be made incorrectly. |
