front 1 why is the nucleus called the control center of the cell | back 1 Because it controls all of the activities of the cell |
front 2 What is a gene | back 2 a gene is a segment of dna that codes for a particular protein which in turn codes for a trait. |
front 3 where in the cell are chromosomes located | back 3 they are located in the nucleus of the cell |
front 4 dna can be found in what organelles | back 4 it can be found in the nucleus, the chloroplasts and the mitochondria. |
front 5 which two scientists established the structure of dna | back 5 James Watson and Francis Crick |
front 6 Replication is called semi conservative because half of the original strand is | back 6 saved, conserved |
front 7 what are the sides of the dna ladder made of | back 7 They're made up of alternating sugar and phosphate |
front 8 what are the 4 bases that make up the rungs of the Dna ladder | back 8 A (adenine) T (thymine) C (cytosine) G (guanine) |
front 9 what sugar is found in Dna | back 9 Deoxyribose |
front 10 What sugar is found in Rna | back 10 ribose |
front 11 what base bonds with A (adenine) | back 11 T (thymine) |
front 12 What base binds with C (cytosine) | back 12 G (guanine) |
front 13 Why is Rna necessary to act as a messenger | back 13 Because the Dna is too big to go through the nuclear pores. |
front 14 Proteins are made where in the cell | back 14 The ribosomes |
front 15 How is Rna different from Dna | back 15 Rna has no thymine, Dna is a double strand while Rna is a single strand, and Rna has ribose sugar while Dna has deoxyribose |
front 16 The process of copying DNa is called | back 16 Replication |
front 17 What is the shape of Dna | back 17 A twisted ladder |
front 18 Proteins are made from what subunits | back 18 Amino acids |
front 19 what base is found in mRNA bud not DNA | back 19 Uracil |
front 20 How is is that some cells become brain cells and others become skin cell even though all the dna is exactly the same. The instructions are the same. | back 20 Because it has become apparent that a celll has the ability to turn off most genes and only work with the genes necessary to do the job. |
front 21 Why is Dna called the blueprint of life | back 21 It's called this because the Dna tells the cell how to build the organism. Every cell in our body has the same Dna |
front 22 what units make up Dna | back 22 Nucleotides |
front 23 What does Dna Look like | back 23 it looks like a twisted ladder |
front 24 how does dna copy itself | back 24 It copies itself by copying its genetic information |
front 25 What holds the sides of the dna ladders togerther | back 25 Hydrogen bonds |
front 26 What’s the full name of dna | back 26 Deoxyribonucleic acid |
front 27 What are A T C and G known as | back 27 Nitrogen bases |
