Question
Normal Text Box S 6 Again, considering the above protein, a missense mutation in base pair 34 causing a change in Amino acid from Leucine to Serine will cause a change in the structure of the protein A True B. False 7. In a double stranded molecule, the 3' end is characterized by the presence awhanging off the end A. A phosphate group B. A promoter sequence ?. Aprimer D. An OH (hydroxy) group 8. An mRNA strand being translated into a protein is 660 base pairs long. how many amino acids long will the protein be? A 660 B. 1980 C. 220 D. 330 9. ? . cell begins with 16 chromosomes in G1, after the S phase, how many Sater chromatids will the growing cell have going into G2? A 16 8. 32 D. 20 10 The cell has at least three checkpoints during cell division, one of which occurs after G, what is most ikely the resulk of skipping this checkpoint? Mutations in the DNA win bt replicated 8. The cell will tall to pull sister chromatids apart C The cell will fail to replicate the cytoplasm D. Mitosis will come to a stop 11 Which of the follawing are exact replicates of each other? A Hamplogous chromosomes B. Analogous chrom osomes C. RNA and DNA polymerase D Sister Chromatids ayout ViewSec1 Pages2 of 3Words:0 of 649LExplanation / Answer
7. d)an (OH) hydroxyl group
Explanation:- double stranded DNA will be composed of 2 single strands running in opposite direction(5'-3' and 3'-5').In a normal DNA 3' end will be composed of hydroxyl group where new NUCLEOTIDES will come and attach by forming phospho diester bond
8. C)220
Explanation: 1 Amino acid will be coded by 3 nucleotides(3 base pairs) so 660/3= 220 Amino acids
9.B) 32
explanation: S phase is also called as synthesis phase where DNA replication will occur ,so when 16 chromosomes enter into S Phase,it will be doubled and results in 32 chromosomes
10.a) mutations in the DNA will be replicated
In G1 check point any mutation in the DNA will be identified and rectified. If it passes G1 check point ,mutations will be replicated as such.
11.d) sister chromatids
Sister chromatids are formed by replication in synthesis phase( S phase) so that both will be exact replicas of each other.
