The genetic code
The genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated intoproteins (amino acid sequences) by living cells
Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.
Each nucleotide sub-unit consists of a phosphate, deoxyribose sugar and one of the 4 nitrogenous nucleotide bases.
code of different functions =)
genes
same traitsthe same traits as each other. Different chromosome pairs code for different traits than other chromosome pairs do though. Only homologous chromosomes (chromosome pairs) code for the same trait as each other.
It is a polygenic character
Genes that are located on the same chromosome are called linked genes. These genes tend to be inherited together during cell division because they are physically close to each other on the same chromosome.

No, DNA and genes are not the same thing. DNA is the molecule that carries genetic information, while genes are specific segments of DNA that code for specific traits or characteristics.
Homologous chromosomes carry genes for the same traits at corresponding loci. They are similar in size and shape and are inherited from each parent.
Homozygous.
The question should be "If two alleles for a gene are the same, what phenotype will the organism have?" Answer: If the two alleles are for the dominant phenotype, the organism will exhibit the dominant phenotype. If the two alleles are for the recessive phenotype, the organism will have the recessive phenotype.
Genes code for proteins
Animals don't share the same genetic code, we share the same chemical building blocks - aminoacids that make genes.
Yes, proteins do not code for genes in the process of genetic expression. Genes code for proteins through the process of transcription and translation.
Yes, linked genes are genes located on the same chromosome.

No, not all genes code for proteins. Some genes code for other types of molecules, such as RNA, which play important roles in regulating gene expression and other cellular processes.
