what do the ATCG ratios have to add up to?

enzyme that unwinds DNA (breaking hydrogen)

builds a new DNA strand by adding complementary bases

the strand that is copied in a continous way

how many hydrogen bonds are C and G next to?

sections of copied DNA created on the lagging strand

What chromosomes are for biological males vs biological females?

What was the first nucleotide discovered?

What molecule brings this information outside of the nucleus?

What structure allows the information held in DNA to get outside of the nucleus to make protein?

What enzyme is involved in keeping the ends from getting shortened (more or less)

What is the mistake rate (before proofreading) in DNA replication by DNA Pol III?

Diploid cells have two sets of chromosomes, one set inherited from each parent, that form ______________ __________.

What is an allele?A. the recessive form of a geneB. the dominant form of a geneC. an alternative version of a geneD. a type of chromosomeE. a variety of pea plant used by Mendel

Variations in inherited characteristics is due to the presence of _______, which are alternative versions of ________.

Which of the following is true about a plant with the genotype AABbcc?A. it has recessive alleles at three lociB. it will not express the recessive c alleleC. it is homozygous at two lociD. it is triploidE. it is heterozygous at two loci

In pea plants, the purple allele is sufficient for making purple flowers, even if one of the homologous chromosomes carries the white allele. Which of the following statements are true in this case?A. Purple flowers will be produced, unless the enzyme that prevents the synthesis of purple pigment is present.B. The white allele is the recessive allele.C. One purple allele results in enough purple pigment for the flowers to be purple.D. The purple allele is the dominant allele.E. White flowers are the dominant trait, unless the enzyme that leads to the synthesis of white pigment is absent.

In his breeding experiments, Mendel first crossed true-breeding plants to produce a second generation, which were then allowed to self-pollinate to generate the offspring. How do we name these three generations?A. F1, F2, and F3B. F, P1, and P2C. P, F1, and F2D. P1, P2, and FE. P1, P2, and P3

The homologs of a chromosome pair contain the same genetic loci. Therefore, each genetic locus is represented _______ in a diploid cell.
