Why are start and end amino acids encoded by only one codon?

Answers

Answer 1

Answer:

The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

What could be the effects of a population changing drastically over a short period of time?

Answers

Answer: Causes of population decline

The size and demographics of the population change when:

fewer children are born;

families with children move to larger towns and cities;

young and better-educated people move to larger towns and cities.

Effects of population decline

When young people move to bigger towns and cities, the average age of the population in the place they leave behind automatically goes up. A community with a higher proportion of older inhabitants may be less attractive to businesses, which may additionally have difficulty finding suitable staff locally. Other effects of population decline include:

fewer schools, due to there being fewer children;

a drop in house prices because more homes are unoccupied;

fewer new homes being built;

less demand for rented accommodation;

fewer care facilities;

less turnover for shopkeepers and businesses;

fewer sports facilities;

fewer people going to the theatre, cinema or concerts, so these facilities are eventually cut back;

fewer people travelling by public transport, which thus costlier to run;

local residents have to travel further to reach the facilities they want.

In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients. Just as humans mine mountains and cultivate soil, rock and soil provide resources for plants, and plants cycle the nutrients through so they (usually) end up back in the ground where they began.

The axon of a sending neuron is separated from the dendrite of a receiving neuron by a.

Answers

During neuronal communication, the axon of a sending neuron is separated from the dendrite of a receiving neuron by a synaptic gap, also known as synaptic cleft or space.

What is the synaptic gap?

During synapsis, a presynaptic neuron sends information to the postzynaptic cell.

The axon of the sending neuron releases neurotransmitters through exocytosis forward to the dendrite of the postsynaptic cell.

The synaptic gap, or synaptic space, is the space left between the axon of the sending neuron and the postynaptic membranes.

The neurotransmitter travels through the synaptic gap forward to the other neuron.

Once it reaches the target, it binds to its receptors in the postsynaptic membrane.

This binding produces a depolarization of the cell called an excitatory postsynaptic potential.

So, the axon of a sending neuron is separated from the dendrite of a receiving neuron by a synaptic gap, also known as synaptic space.
