Genetics

The two strands of DNA are said to be ___ to each other since adenine is always across the molecule from thymine and cytosine is always across the molecule from guanine. Pick the best answer. Complementary The nucleotides along each strand of DNA are joined by ____ bonds. ___ bonds join one nucleotide to the next along a strand of RNA. Phosphodiester Is the helical coiling shown in this picture a right-handed or left-handed coil? Right-Handed Coil X-ray diffraction experiments conducted...

Chromosomes How many nitrogenous bases are found in DNA? Four What two nitrogenous bases are purines? Adenine and Guanine What two nitrogenous bases are pyrimidines? Cytosine and Thymine Adenine always pairs with... Thymine Cytosine always pairs with... Guanine What chemical bond holds the nitrogenous base ...

The roads are information stored inside the Nucleus which is chromosomes that contain many genes The largest amount of DNA in a plant cell is contained in A nucleus Genes involved in the production of abnormal red blood cells have an abnormal sequence of Bases The diagram below represents an incomplete section of DNA molecule. The boxes represent unified basis. What will be the total number of bases represented by the letter A( both inside and outside the boxes) when the boxes are complete...

Which would NOT be an effective way to diagnose sickle cell anemia? A Enzymatic assay for hemoglobin activity. B PCR exon 1 of the b-globin gene, followed by ASO hybridization with oligonucleotides specific for normal and betaS alleles. C Restriction digest of genomic DNA with MstII, followed by Southern blot, using a b-globin gene product. D PCR exon 1 of the b-globin gene, followed by restriction digest with MstII. E Hemoglobin electrophoresis. A All of the following provide supporting ...

A pea plant heterozygous for height and seed color (TtYy) is crossed with a pea plant heterozygous for height but homozygous for seed color (Ttyy). If 80 offspring are produced, how many are expected to be tall and have yellow seeds? 30 offspring How many sets of chromosomes are in a diploid cell? Two sets The gene map of a fruit fly's chromosomes shows the relative locations of the star eye, dumpy wing, and black body genes to be 1.3, 13.0, and 48.5. Between which two genes does crossing...

genetics The scientific study of heredity, or delivery of characteristics from parent to offspring, known as _____ is the key to understanding what makes each organism unique. Gregor Mendel Concluded that traits are inherited through the passing of factors from parents to offspring. fertilization During sexual reproduction, male and female reproductive cells join in a process known as ________ to produce a new cell. True breeding "____________," meaning that they were self- polli...

Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is true breeding for yellow seeds? The offspring will inherit one allele from each parent. What is a gene? A section of DNA Some people have freckles, and some people do not have freckles. If a child has freckles, at least one parent has freckles. However, the child may have a sibling that does not have freckles. Which statement best describes the...

Genetics The study of heredity Gregor Mendel The father of modern genetics Chromosomes found in the nucleus and carry genes 1822 Year Gregor Mendel was born pea plants plant studied by Gregor Mendel Genotype The genetic makeup of an organism Alleles varients or differences in a gene Phenotype An organism's physical appearance, or visible traits. Dominant

Mendel was able to study seven traits in all the pea plants in each generation. Which of his hypotheses allowed him to analyze each trait separately? Wrong. For each inherited trait, there is only one copy of the gene that codes for that trait. If a scientist wanted to follow Mendel's experiment with a different kind of plant, which type of plant would she examine? A plant that has only two alleles for a trait.
