PLS HELP URGENT!!!!!!! The nucleus of a neuron is located in the _____. synapse cell body axon dendrite

1 answer:

3 0

The Nucleus of a neuron is an oval shaped membrane-bound structure found in the soma or body of the neuron. It contains the nucleolus and chromosomes, necessary for the coded production of proteins within the cell. The nucleolus of the nucleus produces ribosomes. The genetic information of an organism is coded within the long strands of deoxyribonucleic acid (DNA) from which the chromosomes are made. DNA is composed of two long chains that are interconnected in a helical arrangement. The sub units of a chromosome (genes) when activated induce the production of messenger ribonucleic acid (mRNA). mRNA is a duplicate of the information contained in the gene. mRNA leaves the nucleus and attaches to a ribosome, where is serves as a template for the production of a protein molecule

Parts of a neuron

Neurons vary in size, shape, and structure depending on their role and location. However, nearly all neurons have three essential parts: a cell body, an axon, and dendrites.

1. Cell body

2. Axon

3. Dendrites

Myelinated neurons are typically found in the peripheral nerves (sensory and motor neurons), while non-myelinated neurons are found in the brain and spinal cord. Dendrites or nerve endings.

The round pea seed trait is dominant over the wrinkled pea seed trait. If the phenotype of a pea seed is wrinkled, which combina

vovikov84 [41]

The wrinkled pea will have two recessive alleles on the locus.

Explanation:

Two forms of same gene are called alleles of that gene.

The allele that expresses itself under heterozygous condition is called the Dominant allele.

The recessive allele can express itself only if they are under homozygous combination i.e. both the alleles on homologous chromosome are recessive.

Here wrinkled pea is a recessive trait and if it is expressed in the phenotype then the genotype of the plant must be homozygous for the recessive allele.

Answer:

The values that most closely represent the expected number of Janice blonde-haired offspring is 252 individuals, option C.

Explanation:

Available data:

Two diallelic genes acting in a recessive epistatic manner to express hair color
Allele A is dominant over the allele a
Allele B is dominant over the allele b
A_B_ Cookie monster blue
aaB_ Elmo red
__bb Janice blonde

When talking about epistasis, we are referring to an interruption. These are interactions between genes located in different loci in the same chromosome. An epistatic gene can alter, influence, or suppress the expression of a hypostatic gene. When the epistatic gene is recessive, the interaction is known as recessive epistasis.

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.

In recessive epistasis, the proportion is 9:3:4.

4/16 individuals are expected to be Janice blond, A-bb + aabb

16 ------------------------------------------- 1000 individuals

4 Janice blond individuals ---------- X = 250 individuals

So, 250 individuals are expected to be Janice blonde. The observed number might vary a little bit from this value. The values that most closely represent the expected number of Janice blonde-haired offspring is c = 252 individuals
