Question | Answer |
is DNA and deoxyribonucleic acid the same thing? | Yes |
what is DNA? | It contains information that helps an organism develop and function. |
what is deoxyribonucleic made of? | It is made up of nucleotides |
what is nucleotides made of? | it is made of a 5-carbon sugar (deoxyribose), a nitrogen-containing base (attached to the sugar), and a phosphate group. |
where are the segments of DNA located? | in the chromosomes |
When a gene is expressed what happens? | a protein is synthesized and produces a trait |
where do the segments of DNA do? | they carry information for certain traits witch are called genes |
DNA is composed of two polymers, where can they be found? | in a helix structure, giving DNA the nickname "the double helix". |
What is the backbone of DNA made of? | it's made of sugars and phosphate groups, which are bonded together. |
how are the polymers linked together? | by nitrogen bases, which attach to the sugars. |
what do the bases of DNA pair with? | They pair with complementary bases on the other polymer in order to link the polymers together. |
Name 4 nitrogen bases | 1. adenine (A) 2. cytosine (C) 3. guanine (G) 4. thymine (T) |
Three bases in a row make up a...? | Codon |
when all of the codons have been read what happens? | the amino acids group together to form proteins. |
How many steps are in DNA replication? | 3 |
Whats the first step in DNA replication? | The two original strands of DNA separate. |
What is the second step in DNA replication? | DNA polymerases add complementary nucleotides to each strand. (adenine bonds with thymine; cytosine bonds with guanine) |
What is the third step in DNA replication? | Two DNA molecules form, which are identical to the original DNA molecule. |
How does the process of DNA of replication begin? | The process of DNA replication begins with one double-stranded molecule of DNA. |
What happens in the DNA replication? | The two strands of this molecule separate during replication, and DNA polymerases add complementary nucleotides to each strand. |
At the end of DNA replications what are your results? | The end results of DNA replication are two identical DNA molecules. |
What happens during transcription? | initiation elongation termination |
what happens in initiation? | Enzymes bind to a DNA sequence and unzip the molecule. |
what happens in elongation? | As the molecule unzips, RNA nucleotides pair to complementary DNA nucleotides on one of the DNA strands. |
