1) Brown fur colour is dominant, gray colour is recessive.
2) Alleles for brown colour is Bb and alleles for gray colour is bb.
3) The parents are heterozygous dominant that is each one of them has one allele for recessive trait gray colour.
Explanation:
Alleles for fur colour brown is dominant
Alleles for fur colour gray is recessive.
Genotype for brown is BB, Bb
genotype for gray colour is bb
Two brown mated producing gray offspring must be heterozygous. the punnet square shows:
B b
B BB Bb
b Bb bb
75% of offspring are brown
25% of offspring are gray 3:1 phenotypic ratio, genotypic ratio 1:2:1
From the punnet square
The brown colour is dominant.
The gray colour is recessive.
Alleles gray colour is bb
alleles for brown is BB, Bb
The parents are heterozygous that is why when two recessive alleles combine of either parents in a progeny gray colour is expressed.
Explanation:
DNA: 3'-5' - ATC GCC CGT
mRNA: 5'-3'- UAG CGG GCA
RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes; RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.
Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.
In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis. Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.

Answer:
A) Atoms share one or more pairs of electrons.
Explanation:
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability.
Nucleus – known as the brain of the
cell
Cell membrane – gives protection to
the cell and helps holding together the organelles
Cytoplasm – jelly-like substance that
holds together the organelles.
Endoplasmic Reticulum – consists of
smooth endoplasmic reticulum which lacks ribosomes, and rough endoplasmic reticulum
which has ribosomes.
Ribosomes – consists of RNA and
protein enzyme and helps in protein synthesis
Mitochondria – known as the powerhouse
of the cell and helps transport energy all throughout the cell
Golgi Apparatus – gather proteins and
lipids in the cell and distribute it.
Centrioles – releases spindle like
formations that is attached to the cell in one of the cell division stages
Lysosomes – helps breakdown larger
molecules to smaller molecules
<span>Vacuole – food and water is stored
here. It also store waste material
before it is transported outside of the cell.</span>
