Answer:
an error in dna replication would affect many generations of cells
Explanation:
because DNA replication contains essentially all the genetic materials that will be needed in transcription and translation processes. And DNA replication is first step to ensure correct protein synthesis and others as well. But translation and transcription are both important to be exact, actually as incorrect transcription or translation could lead to useless proteins or etc.
Answer: Chloroplasts
Explanation: Chloroplasts turn light energy from the sun to sugar.
Answer:
a. a portion of the population becomes isolated from the remainder of the population and experiences different selective pressures
Explanation:
This is an example of allopatric speciation Allopatric speciation is a form of speciation (formation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
New populations evolve as result of mutation, genetic drift and natural selection.
For example, Galapagos finches are isolated from others by the ocean (geographic isolation). Because of the isolation, the finches don’t breed with one another. So, they developed unique characteristics and became endemic.
Answer:
"GFP contained in synaptic vesicles moved into the synaptic cleft by exocytosis."
Explanation:
Synaptic vesicles are small membrane sacs that carry neurotransmitters from the cell body where they are produced, to the presynaptic membrane of the terminal button where they are released. The release zone of the presynaptic membrane contains voltage-dependent calcium channels. When an action potential depolarizes the presynaptic plasma membrane,
-channels open, and
flows into the nerve terminal to trigger the exocytosis of synaptic vesicles, thereby releasing their neurotransmitters into the synaptic cleft
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes
