How did evidence from the study of metabolic defects contribute to the fundamental relationship between genes and proteins? - ANSWER -Garrod suggested that genes dictate phenotypes through enzymes that catalyze specific chemical reactions -Symptoms of an inherited disease reflected inability to synthesize a certain enzyme. -Linking genes to enzymes required understanding that cells synthesize and degrade molecules in a series of steps called the metabolic pathway. Describe the experiment by...

Biology – Genetics (2023/2024) 100% Pass allele Form of a gene. Each characteristic has two alleles. recessive trait that will only appear in the phenotype if organism inherits two of them; covered up by the dominant gene gamete sex cell; sperm or egg adenine A base thats found in DNA. It will only bond with Thymine. amino acid Building blocks of protein asexual reproduction Reproduction of identical offspring from a single parent. No gametes involved autosomes Any chromosome other than ...

Gene Expression - Process by which DNA directs protein synthesis; transcription and translation Transcription - Synthesis of RNA under DNA direction; Produces mRNA; use same language Translation - Synthesis of polypeptide under RNA direction; Nucleic acids and amino acids use different language, Ribosomes are site of translation Triplet code - Series of three-nucleotides (make amino acids) Template strand - Provides template for RNA transcription mRNA base triplets - Codons Direction codo...

The structure of a strand of DNA. - it is a double helix, like a twisted ladder. the ladder rings are nucleotide subunits and they have a covalent bond to the sugar phosphate backbone (made of deoxyribose and a phosphate group) What are the nucleotide subunits? - adenine, guanine, cytosine, and thymine How are the subunits held together? - through a hydrogen bond What are the nucleotide subunits compliments? - Adenine and thymine cytosine and guanine How does DNA replicate? - the parent s...

cystic fibrosis - The nurse is caring for a patient with a genetic disease that is transmitted through autosomal recessive inheritance. Which is the most likely diagnoses for this patient? protect cells from injury - Adaptive cellular mechanisms function to: brain - If a patient has liquefactive necrosis, which organ should the nurse asses first? Huntington's disease - The nurse in the genetics clinic is describing a genetic disease that leads to progressive dementia in the middle to later...

DNA (deoxyribonucleic acid) An organisms genetic material found in the nucleus of a cell Double stranded helical nucleic acid molecule consisting of nucleotide monomers with deoxyribose sugar and nitrogenous bases (A, C, G, T) capable of replicating Which nucleotides/bases are used in DNA? A - Adenine C - Cystine G - Guanine T - Thymine RNA (ribonucleic acid) A nucleic acid consisting of nucleotide monomers with a ribose sugar and nitrogenous bases (A, C, G, U) Usually ...

BAP Final Exam Test Questions With Correct Answers Graded A+ A researcher is investigating that relationship between the existing species diversity in a community and the ability of an introduced non-native species to destabilize the community. Which of the following graphs is most consistent with the claim that communities with high diversity are more resistant to change than are communities with low diversity?as species diversity increases, survival of invaders decreases because mor...

Which is the most likely diagnosis? correct answers Cystic Fibrosis Adaptive cellular mechanisms function to: correct answers protect cells from injury If a patient liquefactive necrosis, which organ should the nurse asses first? correct answers Brain The nurse in the genetics clinic is describing a genetic disease that leads to progressive dementia in middle to late adu...

a synthetic mRNA is created by random polymerization of an equal mixture of C bearing and G bearing ribonucleotides. according to the codon table, what is the expected amino acid composition of the resulting polypeptide product? - equal amounts of Ala, Arg, Gly and Pro a synthetic RNA sequence 5'UUUUUU....UUUUUCN 3', where the N stands for any nucleotide, codes for polyphenylalanine (Phe) that terminates with a single serine. what does this result? - the codons 5' UCN 3' all code for se...
