Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and...

Males and Females are equally affected Autosomal The process of copying DNA in the lab. Polymerase Chain Reaction (PCR) Template DNA, Nucleotides (dNTPS), DNA Polymerase, and DNA Primers. What is needed for Polymerase Chain Reaction? Denaturing, Annealing, Elongating What ar...

RNA polymerase Enzyme that facilitates transcription Transcription synthesis of an RNA molecule from a DNA template Ribosome Large macromolecular complex where proteins are synthesized tRNA (transfer RNA) Form of RNA that is complementary to mRNA. Has a neucleotide anticodo...

Hemophilia Pedigree - Father has hemophilia, mother does not. What is the outcome for their kids? His daughters would be carriers. This is x-link recessive. Autosomal: Dominant: Autosomal: males and females equally affected. Dominant: non-carrier parents polymerase chain reaction (...

Bohr Effect chart (low pH) C- High CO2 H- High H+ A- Acidic R-Release of O2(rt. Shift) T- tense state (in tissues) Primary structure Sequence of amino acids that make up a protein Secondary Structure Sequence of amino acids fold. Tertiary Structure -more folding in a 3D ...

What is the complementary sequence for the following DNA sequence? 5’ – GCC ATC TCG AAT – 3’ 5’ – ATT CGA GAT GGC – 3’ Assuming 100% reaction efficiency, how many DNA copies are created after the completion of four complete PCR cycles? 16 What is the function of...

DNA replication is semiconservative, meaning that each new duplex has one original (parent) strand and one new strand. Because the two parent strands are separated during replication and the base pairing is predictable, each parent strand can serve as a template for the new strand synthesis. DNA re...

[[] PCR- know the steps 1) denaturation: heated to 95C to separate it** 2) annealing (cool to 50*C for sticking) 3) elongation (reaction heated to 70*C to build new DNA) ***ligase is NOT involved Ingredients for PCR: Template DNA Nucleotides (dNTPs) DNA Polymerase DNA primers...

DNA replication is ___________, meaning that each new duplex has one original (parent) strand and one new strand. semi conservative Because the two parent strands are separated during replication and the base pairing is predictable, each parent strand can serve as a ____________for the new s...

Which mRNA sequence results in a polypeptide that contains three amino acids? 5' - CUU GAU ACU UAG - 3' Which template strand DNA sequence would result in the amino acid (Ser)? 5' - CGA - 3' Pay attention. The TEMPLATE STRAND DNA is a 3'-5' so it's flipped. What is the comp...

hemoglobin has how many subunits that can bind heme to iron to oxygen? 4 myoglobin has how many subunits? 1 myoglobin vs hemoglobin: has higher affinity for oxygen? myoglobin _______________ is more saturated with O2 in smaller amounts of O2 myoglobin vs hemoglobin myoglob...

DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the new strands true Recall that the DNA polymerase must bind a double-stranded polymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in...
