Chapter 10 and 11– Homework 1. Describe the stages of transcription. Initiation- Initiator tRNA binds to small ribosomal subunit. Small subunit/tRNA complex attaches to mRNA and moves along it to an AUG “start” codon. Large ribosomal subunit joins complex. Initiation must occur in the order listed above. Elongation- mRNA passes through ribosomal subunits. tRNAs deliver amino acids to the ribosomal binding site in the order specified by the mRNA. Peptide bonds form between the amino acids and

A single _______________ cell (male) penetrates the outer coating of the ____________ (female) and fuses to form one fertilized cell. A _________________ is a fertilized egg with 100 cells that become increasingly diverse. At about 14 days the zygote turns into an _______________ (a and b). At _____ weeks‚ an embryo turns into a _______________ (c and d). ___________________ are chemicals or viruses that can enter the placenta and harm the developing fetus. Fetal Alcohol Syndrome

It is estimated that about 8 million children per year (6%) are born with serious genetic disorders. Imagine going to the doctor’s office on a sunny day with your partner‚ just to find out that you are carriers of a genetic disease which will most likely result in your baby’s death. All your dreams and hopes would be crashed and your hearts broken. What if you were then told that there’s a way science could solve this global issue? The term “Designer Babies” has been thought of as science fiction

"We Do Abortions Here: A Nurse’s Story" by Sallie Tisdale‚ Published in The Norton Reader (Shorter 14th edition) pages 114-120. Nurse Tisdale article depicts personal accounts of her involvement during routine clinical abortions. Tisdale feels the need to justify society’s lack of compassion and inability to comprehend the sheer magnitude of pain‚ suffering‚ and unnecessary death associated with legalized abortion. The U.S Supreme court ruled in favor of legalized second trimester abortion following

mother ’s egg cell and the developing child gets half of its genetic information‚ in the form of DNA‚ from the mother‚ which resides inside in the egg‚ and half from the father‚ which is found in the sperm. The resulting single cell is called a zygote. The zygote spends the next few days traveling down the Fallopian tube and divides to form many attached cells. A ball of cells is produced‚ each cell including a copy of the genes that will

creation of an organism that is the exact genetic copy of another. There are multiple ways that cloning can be achieved through biotechnology. Artificial embryo twinning is the more basic version of cloning. It mimics the natural occurrence of twins as a zygote divides into a two celled embryo but this process takes place in a Petri-dish instead of the mother’s body. The resulting embryos are then placed in a surrogate mother where they are developed. The process that ‘cloning’ generally refers to is scientifically

search Identical twins start out as genetically identical: they have the same alleles. They are formed by a fertilised egg dividing into two separate individuals‚ and are always of the same sex. They may be calledmonozygotic or MZ twins (mono = one; zygote = fertilised egg). They contrast with fraternal twins‚ who are formed by two separate eggs fertilised by two separate sperms‚ and who are not always the same sex (DZ = dizygotic). Both types of twin are carried in the same uterus at the same time

The Circadian clock generates physiological and behavioral rhythms with a period roughly 24 hours. It is thought that Circadian dysfunctions underlie the pathogenesis of many psychiatric disorders such as mania-like behavior and bipolar disorder (McClung‚ 2013). Attention Deficit Hyperactivity Disorder (ADHD) is one of the most widespread psychiatric disorders in humans. Somewhere between 3 and 5% of the population is affected by ADHD (Geissler and Lesch‚ 2011). The ADHD phenotype is characterized
