Label the following nucleotide
Which of the following are pyrimidines?
Thymine
Adenine
Guanine
Cytosine
DNA is a double helix made of two parallel strands of tides linked by -bonding between mentary pair.
Complete the following statement with the correct number. (Do not spell the number)
There are chromosomes in "regular cells".
How many histone molecules combine to make a single bead?
5
8
13
24
Only a purine will fit with a pyrimidine between the sugar-phosphate backbones, when base pairing occurs.
The lagging strand goes in a 3 prime to 5 prime direction.
The decoding of mRNA into a protein is called translation transcription initiation elongation termination( translation, transcription, initiation, elongation, termination ).
❌ is too large to leave the nucleus, but ❌ can. Therefore ❌ and is used as a template to assemble ❌ nucleotides into ❌.
Which of the following unzips DNA?
RNA polymerase
DNA polymerase
RNA primer
DNA primer
Who was responsible for creating the endosymbiotic theory?
Pasteur
Rosalin Franklin
Watson and Crick
Miller and Urey
In eukaryotic chromosomes, replication can be initiated at several different points whilst in prokaryotes the entire genome is replicated at once.
At the leading strand, DNA splits the into its two anti- strands, creating a replication .
Genetic information is copied from ❌ because ❌ is too large to leave the nucleus, but ❌ can. Therefore ❌ is temporarily unzipped by ❌ and is used as a ❌ to assemble complementary nucleotides into ❌. The ❌ then goes through the pores of the ❌ into the cytoplasm to attach to a ❌. This process is called transcription.
A codon is a series of adjacent bases in a NA molecule that codes for a specific .
Label the following diagram of translation
The mRNA that is released at the end of transcription is called pre-mRNA tRNA( mRNA, tRNA ). pre-mRNA pre-tRNA( pre-mRNA, pre-tRNA ) needs to undergo changes before it is exported out of imported into( exported out of, imported into ) the nucleus cytoplasm membrane( nucleus, cytoplasm, membrane ) to protect it from the cytoplasmic environment.
The anticodon goes in a ' -> ' direction.
Ribosomes are the site of which of the following processes?
protein synthesis
meiosis
mitosis
A ribosome alone cannot synthesize a polypeptide chain.
The intitial pre-MRNA contains ons that are removed from the pre-mRNA by somes, while the ons are spliced together.
The following enzymes are involved in DNA replication. Match the enzymes with their functions.
Helicase - ❌ DNA Polymerase III - ❌ Ligase - ❌ DNA Polymerase - ❌
Label the diagram about mitosis.
Label the following ribosome during translation.
