Question

Dominant traits are features only expressed due to chromosomal damage True False They are both correct None is correct Were you to want to review your ancestral tree, you would probable want to construct a punnett square (Not reviewed) Very True Very false I was absent the day this was discussed I left class early the day this was discussed The sequence of protein translation is? Termination-initiation-elongation Initiation-Termination-elongation Initiation-elongation-termination Initiation-transcription-translation None of the above is true Which is correct if you crossbreed F2? l missed this class Chromosomal rearrangement occurs via meiosis I and meiosis II True False They are both correct None is correct The daughter cells from meiosis l and Il cell divisions are 2 and 4 respectively True False They are both correct None is correct

Explanation / Answer

5.Dominant trait are expressed only due to chromosomal damage

D. None is correct

6. Were you want to review your ancestral tree, you would probable want to construct a punnet square

a. Very true

7. The sequence of protein translation is

c. Initiation- elongation-termination

Translation proceede in three phases:

initiaton- the first tRNA is attached at the start codon.

elongation- the tRNA transfers an amino acid to the tRNA corresponding to next codon. The ribosome then moves to next mRNA codon to continue the proces of elocation and thus creates an amino acid chain.

termination - on reaching the stop codon, the polypeptide is released by ribosome.

8. Which one is correct if you crossbreed F2?

d. D

As F1 is heterozygous the resulting F2 geeration is 1:2:1.

9. Chromosomal rearrangement occurs via meiosis I and meiosis II

a. True

During the meiosis I, the chromosome in the cell line up and paired with their correspondind partner nad as the cell begins to divide the chromosome split apart, with one chromosome from each pair ending up in the resulting cells. These cells then enter meiosis II and divide again. At this time each chromosome splitting in half and the resulting cells with each containing half of each chromosome.

10. The daughter cells from meiosis I and II cell division are 2 and 4 respectively

d. None is correct

By meiosis, a diploid parental cell divides twice forming four haploid gametes or sex cells, each having half the DNA amount than that of the parental cell and one -fourth of DNA present in the cell.
