B.5.B
Examine specialized cells, including roots, stems, and leaves of plant; and Animal
cells such as blood, muscle, and epithelium.
Cell Specialization Cell Specialization- It All “Stems”
From A Stem Cell. During The Growth of Individual It Will
Differentiate Into Various Types of Cells Due To Their Specializations.
At The Beginning Of The Development Of An Embryo, It Decides On What Cell Its Going To Be because of the instructions in DNA.
Red Blood Cells They Lose Their
Nuclei They Fill Up A Special
Oxygen-Carrying Molecule, Hemoglobin.
Red Blood Cells Begin Their Journey In The Lungs, Where They Pick up Oxygen From The Air you Breathe.
Epithelial Cells Epithelia Are
Formed Of Cells That Line The Cavities In The Body And Cover Flat Serves LIKE YOUR SKIN.
Neurons A Neuron Is a Nerve
Cell. Neurons Have
Specialized Projections Called Dendrites And Axons.
Dendrites Bring Information To The Cell Body And Axons Take Information Away From The Cell Body.
Muscle Cells Muscle Is A Very Specialized Tissue
That Has Both The Ability To Contract And The Ability To Conduct Electrical Impulses.
3 Types Are; Smooth Involuntary Muscle Voluntary Skeletal Muscle Involuntary Cardiac Muscle

B.6.A
Identify components of DNA, and describe how
information for specifying the traits of an organism is
carried in the DNA
• It is the nitrogen base pairs that code for our genetic traits.
• DNA contains codes for proteins, which are necessary for the growth and functioning of an organism.
• Your DNA forms Chromosome- and within each chromosome are thousands of genes that code for your traits.
Types of Cells• Somatic cells, which are
anything but sex cells have 46 chromosomes.
• Gametes which are sperm and egg cells, contain half the number of chromosomes of somatic cells. They have 23 chromosomes.
B.6.B
• Recognize that components that make up the genetic code are common to all organisms.
• In all living organisms, the instructions for reproducing and operating the individual is encoded in a chemical language with four letters– A, C, T, and G, the initials of four chemicals. Combinations of three of these letters specify each of the amino acids that the cell uses in building proteins.
• every species on Earth carries a genetic code that is, for all intents and purposes, identical and universal. This is used to claim that we all share a common ancestor

53 How does DNA in cells determine an organism’s complex traits?A DNA contains codes for proteins, which are necessary for the growth and functioning of an organism.B DNA separates into long single strands that make up each part of an organism.C DNA produces the energy an organism needs in order to grow.D DNA folds into the nucleus of each of the cells of an organism.

Transcription and Translation
Step 1: Transcription DNARNA
1.Inside the nucleus an enzyme unzips DNA
2. RNA bases A, U, C, and G pair up writing a single stranded messenger that will leave the nucleus and travel to the ribosome
Step 2: Translation RNA Protein
3. where it is read 3 letters at a time called a codon.
4. tRNA brings a specific amino acid to match up with the mRNA and links together with other amino acids using peptide bonds to form the protein, this is called translation.
DNA Sequence! Write mRNA and code for amino acids

Using the CODON CHART
is like the process of
translation. You take a sequence of RNA and turn
it into a set of AMINO ACIDS.
