- What are purines and pyrimidines?
- Briefly describe the difference between Meiosis 1 and Meiosis 2
- What is gradualism?
- What are the 3 types of RNA? Describe each.
- How is gene regulation in prokaryotes different from gene regulation in eukaryotes?
- a Prokaryotes are simpler and uses operons which are groups of genes with closely related functions that respond to environmental demands of the prokaryotic cell
Eukaryotic gene regulation is more complex and can happen before transcription, after transcription or after translation
- b Meiosis 1: 1st phase of meiosis includes crossing over and ends up dividing into 2 diploid cells
Meiosis 2: 2nd phase of meiosis divides the sister chromosomes into 4 genetically unique haploid cells.
- c The idea that large scale changes like formation of a new species require many small changes to build up over a long period of time
- d Purines are bases of DNA (Adenine and Guanine)
-composed of 2 rings of carbon and nitrogen per base
Pyrimidines are bases of DNA (Thymine and Cytosine)
-composed of one ring of carbon and nitrogen atoms per base
- e mRNA formed by transcription, complimentary strand to the DNA sequence of a gene, carries instructions for the making of a protein from the nucleus to the ribosomes
tRNA reads the mRNA by binding to the codon on the mRNA with the anticodon located on one end of the tRNA at the ribosome during translation, carries a specific amino acid for the codon on the other end of the tRNA, translates it into an amino acid sequence when subsequent amino acids are joined together
rRNA together these for the ribosome, is the site of protein synthesis
5 Multiple choice questions
- The making of more of the same species.
The two main types are sexual and asexual reproduction.
Sexual- genetic material is donated from two parents to make a genetically unique offspring.
Asexual- genetic material is donated from one parent to make a genetically identical offspring.
- They are easily accessible
- in DNA, a phosphate group, the sugar deoxyribose and 1 of 4 nitrogen containing bases Adenine, Thymine, Guanine, Cytosine
In RNA, a phosphate group, the sugar ribose, and 1 of 4 nitrogen containing bases Adenine, Uracil, Guanine, Cytosine
- The link between microevolution and macroevolution, and is the formation of new species
5 True/False questions
Describe the proof that evolution happens → Fossil record- shows a pattern of gradual change from past to present
Biogeography- shows that similar environmental conditions contribute to similar development
Developmental biology- shows similarity in embryonic development in organisms deriving from a common ancestor
Anatomy- shows similarity of structures n organisms that are related or descended from a common ancestor
Biochemistry- similarity in amino acid sequences of proteins or DNA give evidence of common ancestry
Briefly describe the diploid life cycle? → Several species of a animal evolving from a common ancestor and through the generations as they move to different environments they all evolve with their environment becoming new species
What are transcription facts? → They regulatory proteins and activate or repress transcription of specific genes
What is punctuated equilibrium? → The idea that large scale changes like formation of a new species require many small changes to build up over a long period of time
Health → The link between microevolution and macroevolution, and is the formation of new species
