Answer:
Option A, B and D apply except C
Explanation:
All DNA contains the same four nitrogenous bases, A, T, C, G and these bases combine in threes to produce 20 amino acids which make proteins.
On the other hand, DNA is transcribed in the nucleus to mRNA transcript and then sent to the cytoplasm for translation. mRNA is then translated to proteins with the aid of the ribosomes. Thus making option C wrong.
Attached is the image concerning the HOXD13 gene along with the regulatory and promotor regions of the gene.
The answer will be "yes; when any of the segments of deleted, the expression level dropped to less than 100% of the control."
The experiment comprises of testing the expression of the HOXD13 mRNA from the gene by deleting segments of the regulatory regions. In the event of deletion of one segment (segment C), the mRNA expression dropped to around 60% of the control. When two segments are deleted (segments B and C), the mRNA expression dropped to less then 40% of the control. When all segments are deleted, the mRNA expression was almost to 0%.
Answer:
A somatic is a cell containing two complete sets of chromosomes, one from each parent.
YOUR ANSWER IS SOMATIC
Explanation:
Answer:
It's either positive feedback or neutral feedback (I can decide which one fits more)
Explanation:
With some fruits, it speeds up the ripening process depending on the rise in ethylene
Options are:
A. a fish
B. an aquatic bird
C. a mosquito
D. a dragonfly
Answer: Fishes
Explanation:
A metapopulation can be defined as a small population that cannot itself make a large population that is stable.Many sub populations are connected intermittently to combine and form a population.
Small population of fishes would have been separated for most of the years and are joined by when floods occur and these populations are connected by kettle ponds.
Rest of the three organism like bird, mosquito and dragon fly cannot be separated so as to form a metapopulation.
