Studying the expression of a transcription regulatory protein in two cell types, you have performed experiments showing that the
mRNA encoding the protein is present at comparable levels in the cytosol of both cell types. However, based on the expression of its target genes, you suspect that the protein activity might be significantly different in the two cell types. Which of the following steps in expression of the gene encoding this protein is more likely to be differentially controlled in these cell types? a.Translation
b.mRNA transport
c.mRNA degradation
d.Transcription
Since the mRNA levels are similar in both cell types, difference in protein activity can be attributed to differences in translation or in post-translational control
Translation is completed in four sequential steps: activation of amino acids (tRNA charging), initiation, elongation and termination
Eukaryotic translation is similar as prokaryotic translation but more complex due to: mRNA require preparation before translation, requirement of preparation of ribosomal small subunit require large number of initiation factors and require scanning of initiation codon
The scientists could determine what are the risks to contract specific diseases, and also what are the chances of transmitting genetic disorders in next generations.
Explanation:
In this case, the scientists may determine what are the mutations that Jennifer could have and how these mutations are associated with diseases and/or genetic disorders
The ocean absorbs carbon dioxide from the atmosphere wherever air meets water. Wind causes waves and turbulence, giving more opportunity for the water to absorb the carbon dioxide. Fish and other animals in the ocean breathe oxygen and give off carbon dioxide (CO2), just like land animals.
I think you forgot to give the options along with the question. i am answering the question based on my knowledge and research. "One group of bears was less highly evolved less than the two other groups and was destined to die out" is the one that explains why only one group of bears were extinct. I hope the answer has helped you.
Your answer is D. <span>There are almost no similarities between the genetic code of these four organisms, and are placed into four different kingdoms.</span>
Two replication forks are formed by the opening of the double-stranded DNA at the origin, and helicase separates the DNA strands, which are coated by single-stranded binding proteins to keep the strands separated. DNA replication occurs in both directions
