Choose all that apply below to dna:

double helix

takes the original code out of the nucleus and translate it into proteins

contains the original code to make proteins

contains thymine

contains uracil

contains guanine

single strand helix

contains adenine

contains cytosine

The DNA: is a double helix, contains the original code to make proteins, contains thymine, contains guanine, contains adenine, contains cytosine

Explanation:

The DNA is a double helix linked to both chains by hydrogen bridge bonds; It is formed by the nitrogen bases Adenina that is paired with Thymine and Cytosine with Guanine, sugar: deoxyribose and phosphate groups. The genome of a certain organism is found in the DNA, that portion of the genome that codes for an RNA or protein is called a gene.

Those genes that code for proteins are composed of "codons" (units of 3 nucleotides), being that each of them codes for an amino acid.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)
