question 8
DNA is copied into mRNA during the process of <u>Transcription</u>
- <u> </u>Transcription is the process by which information in the strand of DNA is copied into new molecule of messenger mRNA.
- The mRNA formed is a complimentary to DNA strand whereby replace of C with G, and A with U and T with A.
Question 9
Translation occurs in the ribosome , the organelle responsible for building proteins.
- Ribosome are responsible for protein synthesis.
- They receive messenger RNA sent from the nucleus and build protein.
- translation has three steps that is
- initiation - ribosome assemble around the target mRNA.
- elongation- The tRNA transfer amino acid to tRNA corresponding to the next codon.
- Three phases of translation initiation polymerase bind to DNA strand and move along until the small ribosomal subunit binds to DNA.
Because men have one copy of the X chromosome
Answer:
75% would have the dominant traits for coat length, 25% would have recessive trait for coat length.
Explanation:
After completing a punnet square, we could find that our genotypes are 25% LL, 50% Ll, and 25% ll.
If these genotypes were to be physically expressed, LL and Ll would both be expressed as showing the dominant trait.
This means that 75% would have the dominant traits for coat length and 25% would have recessive trait for coat length.
I hope this was helpful! Let me know if you need any clarity.
Answer:
C) II and III only
Explanation:
Option 1 is not an example of phenotypic plasticity because each person is born with their own blood type and this doesn't change based on their environment and behavior.
Option 2 is an example of phenotypic plasticity because a person's red blood cell counts can increase based on their environment, i.e. moving to Denver, CO from Death Valley, CA. The higher elevation and decreased oxygen causes your body to produce more red blood cells.
Option 3 is an example of phenotypic plasticity because one twin can be taller than another because of differing behaviors, environments, etc.
