The instructions for the genetic traits of an organism are directly determined by the a-numbers of a, t,c and g units in a sugar molecule b-sequence of the bases in dna molecules c-length of a dna molecules d-way the bases are paired in the two strands of a dna molecule
The answer would be:
B. Sequence of the bases in DNA molecules.
Here is more about your questions:
DNA contain the instructions of the traits of an organism. Most of the organism have the same DNA but what makes each different is the sequence of the DNA. The sequence gives the instructions for the production of amino acid that will produce, which in turn determines what traits will be passed on or manifested by that individual.
The correct answer is D. way the bases are paired in the two strands of a DNA molecule.
The genes determines the traits of an organism and the gene is the segment of DNA which makes polypeptide. DNA is made of polynucleotide and each nucleotide consists of a phosphate, a deoxyribose sugar and a nitrogenous base. The pattern of base pairs in the DNA gives instructions for the synthesis of protein. The type of proteins determines the trait of an organisms.
Explanation: choice a and choice c are very similar, but the phrasing of the words is different. Genes are made up of DNA.

Each eukaryotic chromosome usually has repeated telomere sequences ranging from 2 to as many as 2000.
There is normally just one specialized DNA sequence called the centromere per eukaryotic chromosomal DNA molecule.
The origin of replication is the site where DNA duplication starts in S phase.
The centromere attaches the chromosome to the mitotic spindle via the kinetochore structure.
Teleomere contains repeateted sequences at the ends of the chromosomes.
There are four nitrogenous bases in a DNA including guanine (G), adenine (A), cytosine (C) and Thymine (T) and together they form the nitrogenous base sequence arranged in a specific order of three letters such as GAC and TAG to form a genetic code.
These nitrogenous base sequences forming genetic code are amino acid specific and determine the amino acid sequence in DNA. for example: CTT determines leucine and GTT determines valine.
Hence, the correct option is "3".
A specific sequence of bases in a DNA molecule codes for the lipase enzyme.
The base sequence that codes for the lipase enzyme is duplicated during DNA replication.
In a DNA molecule only a specific sequence known as "gene" codes for functional proteins like enzymes while rest of the part of DNA is regarded as spacer/junk DNA. During cell division, the entire genome i.e. all the chromosomes are duplicated/replicated so that one of the copies is retained in the mother cell while another copy is donated to the daughter cell.
Other two options are wrong because production of RNA molecule is known as transcription not translation and production of lipase enzyme which is a protein is known as translation not transcription.
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.
The sequence of amino acids determines the protein
