Why is mRNA at the ribosome shorter than it was in the nucleus?

40 Transcription and RNA Processing

RNA splicing introns are removed and exons are pasted together.

10The genetic code consists ofTranslation and Genetic Code

Codons (3 nucleotide sequences on mRNA)10Translation and Genetic Code

20What is translation?Translation and Genetic Code

Conversion of nucleic acid language to amino acid language to build a protein20Translation and Genetic Code

30What does tRNA do in translation?Translation and Genetic Code

Joins to a specific amino acid and transfer it by matching its anticodon to the codon on mRNA at the ribosome30Translation and Genetic Code

40What happens during initiation of translation?Translation and Genetic Code

mRNA joins with the small ribosomal subunit, which is then joined by a tRNA, and then joined by the large ribosomal subunit. 40Translation and Genetic Code

50Why is it significant that there are 64 codons for 20 amino acids?Translation and Genetic Code

In terms of transcription and translation, how does genotype determine phenotype?More Translation and Mutations

50More Translation and Mutations

*the information from the gene on DNA that was inherited from parents is the genotype. It is transcribed onto mRNA, and eventually translated into a protein. The protein is the phenotype (expression of the genotype)

10Evolution 1What does the theory of evolution suggest about all living organisms?

10Evolution 1

All living organisms came from a common ancestor.

20Studying preserved organisms in sedimentary rock is used as what?Evolution 1

20Evolution 1Evidence of Evolution

30Evolution 1

When looking at structures that are very similar but different in function, what kind of evidence of evolution are you studying?

30Evolution 1Homologous structures

40Evolution 1A fire wipes out an entire population of organisms. A few survive, reproduce, and give rise to a new population. This is an example of

*Bottleneck effect (Genetic Drift)

50Evolution 1Variation in a population is only significant if what?

50Evolution 1*The variation allows for traits that increase the fitness of the population. *Beneficial traits are heritable and are passed on through reproduction.

10Evolution 2Dark colored moths outnumbered light colored moths in Manchester England during the Industrial Revolution.

How would Lamarck explain this phenomenon?

10Evolution 2

According to his Theory of Evolution by Acquired Characteristics, Lamarck would suggest that the light colored moths turned dark colored, reproduced, and passed on this acquired trait to the next generation.

10Genetics 2

20Evolution 2

Dark colored moths outnumbered light colored moths in Manchester England during the Industrial Revolution.

How would Darwin explain this phenomenon?

Darwin would have explained through his Theory of Evolution by Natural Selection. Light moths were easily seen by predators and therefore more likely to be eaten. Dark moths were naturally selected to survive in that their dark traits allowed them to blend into their environment. The dark moths survived, reproduced, and overtime there were more dark colored moths in the population. 20Evolution 2

30Evolution 2

Variation within a population comes from.

30Evolution 2

*new allele combinations that arise from mutations.

40Evolution 2Darwin observed selective breeding of dogs to help him better understand natural selection. What did he call this type of selective breeding?

50Evolution 2

Upon application of a pesticide in her garden, Sally initially found it to be an effective method to destroy the pests. Within a few months, the pesticide was completely ineffective and her garden was being destroyed by pests. Why did the pesticide become ineffective?What should she do?

50Evolution 2

The pesticide destroyed 99% of the pests, but 1% had a mutation that enabled them immunity to the pesticide. The pesticide-resistant pests then reproduce, and overtime their population increased in the garden.Sally will need to get a new pesticide
