- Where are proteins synthesized?
- If the sequence of nitrogenous bases in a segment of a strand of DNA is
GATACG, what would the sequence of bases in the complementary strand of mRNA
- Describe in detail the process of transcription and translation.
- How does a cell make sure that all the genes in a cell of an organism are
- Why are there two different types of synthesis in DNA replication?
- Proteins are synthesized at the ribosomes.
- The sequence would be: CUAUGC.
- See answer here
- All the genes in a cell of an organism are the same because of DNA
replication. The genes copy themselves exactly, ensuring the same
genes in all cells.
- DNA is read 3' to 5', but it is built 5' to 3'. Since there are two
strands of DNA, one is 3' to 5' and the other is 5' to 3'. DNA works
only by reading DNA 3' to 5', therefore the two strands are replicated
differently. The 3' to 5' strand undergoes continuous synthesis.
It is the leading strand. In the 5' to 3' strand, the DNA polymerase
can't read in this order, therefore it jumps ahead about 1000-2000
nucleotides and replicates DNA in a direction away from the fork. This
is called discontinuous synthesis and this strand is called the lagging
