Bio Lecture 3 exam

During transcriptionRNA polymerase binds to the

intron of the DNA strand.

RNA is synthesized in the 5' to 3' direction, using a DNA template strand that is read in the

opposite driection so 3’5

Mrna carries- Messager RNA

to carry genetic code from the nucleus to the ribosomes.

What is the role of ribosomes during protein synthesis?

To facilitate the translation of mRNA into proteins

Promoter sequence

Sequence where RNA polymerase binds to initiate transcription

Introns are the coding regions that remain in the mature mRNA.

False

tRNA

Transfer RNA that brings amino acids to the ribosome

mRNA

Messagner RNA carries genetic information from dna

Histone proteins

help in condensing DNA into a compact form in the nucleus.

DNA contains uracil as one of its nitrogenous bases.

No its RNA

Introns

The excised parts of gene sequences that do not code for proteins are called

Exons

The __________ are the coding regions of eukaryotic genes that remain in the mature mRNA after processing.

In DNA, the two strands are held together by which type of bonds?

Hydrogen

During which phase does RNA synthesis occur?

Transcription

A - Adenine pairs with

T- Thymine

G-Guanine pairs with

C-Cytosine

Watson and Crick Discovered

How nuceltoides interact with eachother

Dr rosalind Franklin

Undserstood the double helix structure of dna and got a photo

Chromosones carry genes- genetic material intoooo

Protein and stores it as DNA

Base Pairs have

A Sugar Phospate Backboneas

Base pairs are

Nitrogenous Bases

Double Bonds are

Adenine and Thymine

Triple Bonds are

Guanine and Cytosine

Nuceltides/DNA have

One phoshate and Nucletide base and hydrogen bonds

Complimentary strands have

How dna strands match

Dna Replication

Proccess of Dulication of dna

Dna Proofreading

Dna Polymerase corrects eroor during replication

Dna dogma

DNA to RNA to PROTEIN

Locus

Location of bases

During Elongation

RNA polymerase tracks the dna template

Proteins

code for ribomsome for amino acids which are aug-met

AUG- MET

Star condons for each proteins

Mutations

Chnage in nucleotide sequence

Mutations can be

harmfuk but also beenfical in nature or lavatory

CAT GUA bonding are

condons with short tangent repeats

Nucletides can have

base insertations or deletions

Mutagin

Smoking or Tobacco which is the worst one

Homologyy

the similarity of structures, traits, or genes in different species that is inherited from a shared evolutionary ancestor

What is a Phylogenetic Tree

A phylogenetic tree is a family tree for lines of descent among different species, organisms,

What did Carolus Linnaeus do

Propose a two part name for species and Hierachical Classification

Hierarichal Classification - King Philp Came Over For Good Soup

Kingdom, Phylum, Class- Mammalia, Order -Carnivora, Family-Canidae, Genius- Canis, Species- Canis Lupus

Galapagos were young volcanic islands with unique plants and animals and

The common place of orgin of animals

Orgin of Species

Groups of Population with Potenial to interbreed in nature to produce fertile offspring

Mules and Ligers

Arent fertile because they have odd number of chromosomes

Homologus struture example

Cat and human hand

Most Living Cells have

DNA, Ribsome (in Nucleus), Cell Membrane, and Cytoplasm

Prokaryotes have a coat of Protein anddd

thrives in all habitats and cause most human diseases

Two Branches of Prokaryotic Cells

Bacteria and Archaea

ProKaryotes are unicelluar
