CHAPTER 1 -- Part 2: 0
When the remaining exons are attached to the small ribosomal subunit, translation begins.
The first codon is always August.
This attracts something.
The AUG codon is helped by the 5' end being given a guanine cap, which is a molecule carrying methionine.
The large sub attach to the ribosome when this happens.
The ribosome's 3' end contains the A site and the poly-A tail, which may help the P site bind to the complexample.
It does not happen during the construction of post tran.
The answers A, C, D, and E are all incorrect.
TRNA has a long lifespan.
It is similar to a taxi picking up passengers.
They prevent new passengers from delivering from place to place.
The lac operon is a DNA frag genes.
The smaller you are, the more involved you are in gene regulation.
The farther you go, the Barr bodies discussed.
This must be the smallest of the five levels of methylated DNA because C went the farthest in Chapter 10.
The groups have picked out the pieces.
The piece A that was associated with inactive DNA moved the least of the five labeled pieces.
Person 4 should talk to a lawyer.
The nucleus rately match DNA found at crime scenes with and lead the translation of proteins in the ribo potential suspects must be modified before it can be used in forensics.
There are three types of ribosomes.
The double strand is unzipped by helicase and the DNA polymerase adds on the nucleotides.
Errors of process are minimized by proofreading.
When needed, it allows for production of genes.
Lactose is the inducer when present and off when not.
The parasitic infectious agent is unable to survive outside of the host.
There is a Viruses that carries with it reverse transcriptase.
There is an extra circle of DNA present inbacteria.
The four major modes of evolution are discussed in this chapter.
Natural, directional, stabilizing, disruptive, sexual, and artificial are some of the forms of selection it introduces you to.
It touches on the theory behind how life on this planet emerged many years ago and discusses the two main forms of speciation.
There are four major modes of evolution.
Variations, heritability, and differential reproductive success are some of the conditions that determine natural selection.
There are four basic patterns of evolution.
There are sources of variation within populations.
p + q is 1 and p2 + 2pq is 1.
An introduction to the concept of evolution and the four major modes in which it occurs begins the chapter.
Natural selection and the work of Lamarck and Darwin are more important than ever.
We look at the various types of selection, including directional, stabilizing, disruptive, sexual, and artificial selection.
A quick look at the sources of variation within populations is followed by a look at the two main types of speciation.
The yucky math portion of the chapter is the Hardy-Weinberg equation and the conditions necessary for its existence.
The chapter ends with a look at the evidence in support of the theory of evolution and a discussion of how life on this planet came to be.
Evolution describes the change in frequencies in populations over time.
When one generation of organisms reproduces and creates the next, the frequencies of all the genes in the population may be different from what they were in the parent generation.
All individuals have the same allele for that character, even if certain alleles are lost or become fixed.
Random factors or natural selection can change the frequencies.
Big Idea 4.C.4 should consider chance events first.
The diversity of alleles is isolated from other populations of the same species.
Fifty percent of the fish population is killed by a tornado.
Most of the fish killed possess the long-fin allele, and few of these individuals are left with a stable population.
There are fewer fish with long fins in the next generation.
Imagine that the same pond is connected to another pond by a small stream.
All the long-finned fish migrate to the other pond when the two populations mix.
There will be a change in the frequencies in the next generation because the individuals who migrated were random.
