Rosalind Franklin is famous for which contribution to the study of DNA? creation of an accurate model of DNA structure creation of an X-ray diffraction image of DNA structure identification of a pattern in ratios of DNA bases identification of DNA in bandages that contained pus

creation of an X-ray diffraction image of DNA structure

What was Marshall Nirenberg and Heinrich Matthaei's contribution to our current understanding of the genetic code? discovery of codons discovery and extraction of DNA creation of a model of DNA creation of Photo 51

discovery of codons

What basic unit of heredity is found on segments of DNA and are passed on from parent to offspring? nucleotide gene phosphate molecule deoxyribose sugar

gene

Organisms inherit specific traits and characteristics from their parents. Albinism is an inherited disorder that occurs when an organism is unable to produce or distribute melanin. Melanin is a substance in the body that helps determine skin color, hair color, and eye color.Which is the basic unit of heredity that carries the trait of albinism from parent to offspring? base pairs genes proteins codons

genes

As DNA is replicated, which DNA base pair will bond to cytosine? adenine thymine cytosine guanine

guanine

Which is a goal of the Human Genome Project? to identify the 3 billion genes that comprise the human genome to sequence the genome of every living individual to address the ethical consequences of genomic research to measure the length of human DNA

to identify the 3 billion genes that comprise the human genome
