Which characteristics descibe the genetic code of humans? Select three options contains over three billion base pairs, can only understand human genetics, can help explain genetic diseases, composed of about 19000 genes, come post of 23 chromosomes

The options of genetic code characteristics are:

Three billion base pairs

19000 genes

can explain genetic diseases.

Explanation:

Genetic code is the set of 3 RNA base pairs on the mRNA transcript which codes for the amino acid to be added on growing polypeptide chain.

The options are:

Three billion base pairs

19000 genes

can explain genetic diseases.

Genes are the sequence on DNA of the organism which are responsible for the production of protein, phenotype or genotype expression of the gene.

The nucleotides get converted into ribonucleotides in mRNA during the process of transcription.

The mRNA formed has coding (exon) or non coding (introns) sequences. The mRNA transcript after splicing will have only exons. These exons are read by tRNA as they have anticodon for the triplet sequence on mRNA. It brings the correct amino acid for translation to occur.

The gene sequence tells the causative of diseases as what changes in the DNA is the reason for disease like cancer. The gene therapy could be used to replace the defective gene hence genetic level of diseases could be studied.
