A Gram- negative bacteria has a thin cell wall of Peptidoglycan which is sandwiched between the cell membrane and outer membrane. Where as, the Gram positive bacteria has a thick layer of Peptidoglycan outside their cell membrane.
Hence Gram- negative bacteria is different from a Gram- negative bacteria in because it has an extra layer that is outside the Peptidoglycan layer.
Hence the right option is D
This feature of the Gram-negative bacteria does not let crystal violet solution to soak into its Peptidoglycan layer because it is covered by the extra layer where as an Gram- positive bacteria will easy soak into crystal violet solution due to the exposed Peptidoglycan layer.
I think the answer is 6 honey bees since 6/12 =1/2.
Answer:
MRNA is the same as the dna template but instead of T you replace it with U
So the mrna would be
GGG UAU GCU UUC
Explanation:
at the replication fork, you have 2 DNAP's. One is on the leading strand and the other is on the lagging strand. Now you into a problem of DNAP's not moving in sync with each other. The synthesis on the leading strand is much faster than the lagging strand because the lagging strand needs to make an RNA primer and then extend the primer (okazaki fragment synthesis/maturation). So DNA synthesis will not be complete on one of the strands.
There is a model that explains what happens during DNA replication. The model is called the Trombone model.
You have 2 DNAP's linked together by a tau protein (2 tau proteins) and both tau proteins are bounded to beta clamp loader. This makes the holoenzyme complex.
A B C OR D it would most likely be D all of the above :)
