They both have a bilipid cell membrane. This means that their cell membrane is composed of phospholipids. Both cells also have ribosomes. This is a critical cell organelle that is involved in the translation of mRNA to proteins. Their genetic material is also made up of deoxyribose sugars (DNA).
Answer:
The transcription rate will slow down in the cells that carry mutant sigma factor.
Explanation:
Sigma factor play an important role during initiation of transcription.The sigma factor binds to the core RNA polymerase(that contains alpha,beta,beta dash and omega subunit) to form hollow enzyme.
The binding to sigma factor to core RNA polymerase initiates the formation closed promoter complex and the release of sigma factor result in the formation of open promoter complex that signals the ending of transcription initiation.
Now if the sigma factor binds tightly to the core RNA polymerase then it will be difficult for the sigma factor to get dissiciated from hollow enzyme,as a result transcription will remain in the initiation phase. So the process cannot enter the elongation phase.
Answer:
DNA replication
Explanation:
During this process DNA is replicated after its strands are separated by Helicase an enzyme. DNA polymerase then fixes okazaki fragments in the fork and ligase sticks them together to create copies of DNA
Answer:
they are usually associated with extreme weather such as heavy torrential downpours, hail storms, lightning and even tornadoes
Explanation:
hope this helped :)
In plants a cell plate is formed causing the division of the cells.In animal cells a cleavage furrow is formed in the cell membrane and separates the two new cells
