What is DNA

背面 (解答)

Deoxyribonucleic acid is the hereditary material in humans and almost all other organisms.

#2
正面 (问题)

DNA profile

背面 (解答)

A bar code pattern from DNA unique to each organism

#3
正面 (问题)

Hydrogen bond

背面 (解答)

Weak bond between nitrogenous bases in DNA molecule

#4
正面 (问题)

Nuclear pores

背面 (解答)

Openings in nuclear membrane that allow mRNA to leave nucleas.

#5
正面 (问题)

Peptide bond

背面 (解答)

Name of bond that forms between amino acids in protein molecule

#6
正面 (问题)

Replication

背面 (解答)

Process by which DNA molecule makes identical copies of itself

#7
正面 (问题)

Ribose

背面 (解答)

Type of sugar found in an RNA molecule

#8
正面 (问题)

Transcription

背面 (解答)

Stage of protein synthesis during which mRNA forms from DNA

#9
正面 (问题)

Translation

背面 (解答)

Stage of protein synthesis during which tRNA interprets the message on the mRNA to form a specific protein

#10
正面 (问题)

tRNA/transfer RNA

背面 (解答)

Type of nucleic acid that carries a specific amino acid

#11
正面 (问题)

Uracil

背面 (解答)

Nitrogenous base found only in RNA molecules

#12
正面 (问题)

Deoxyribose

背面 (解答)

A sugar molecule found in a nucleotide of DNA

#13
正面 (问题)

Function of DNA

背面 (解答)

Stores an organisms genetic info Controls the production of proteins.

#14
正面 (问题)

Where DNA is located

背面 (解答)

Cell nucleas (nuclear DNA) Mitochondrion (mitochondrial DNA /mtDNA) Chloroplast (Chloroplastic DNA)

#15
正面 (问题)

DNA structure (nucleotide)

背面 (解答)

Deoxyribose sugar, nitrogenous base, phosphate

#16
正面 (问题)

Nitrogenous bases & types

背面 (解答)

Divided into 2 groups which are pyramidines (thymine & cytosine) & purines (adenine & guanine)

#17
正面 (问题)

Why does a purine not bond with purine & pyramidine not bond with a pyramidine

背面 (解答)

Only a pyramidine & purine pairing has width consistent with DNA Purine+purine is too wide Pyramidine+pyramidine is too narrow

#18
正面 (问题)

Shape of dna

背面 (解答)

Double helix

#19
正面 (问题)

DNA supercoiling

背面 (解答)

Refers to the over & under winding of strands. Important for DNA packaging within all cells & reduces the space & allows for much more DNA to be packaged.

#20
正面 (问题)

Complementary base pairing

背面 (解答)

When a specific pyramidine base bonds with a specific purine base

#21
正面 (问题)

Why DNA is called a polymer

背面 (解答)

It is made up of many nucleotides bonded together

#22
正面 (问题)

Nucleotide

背面 (解答)

Building blocks/monomers of nucleic acids

#23
正面 (问题)

DNA & RNA difference

背面 (解答)

RNA has : uracil DNA has: thymine instead RNA has: ribose sugar DNA has: deoxyribose RNA has a single stranded molecule DNA has a double stranded molecule

#24
正面 (问题)

Polynucleotide

背面 (解答)

A very long molecule made up of a string of repeating nucleotides
