SA:V Ratio

1 cm cube Smallest one was most effective because it has less volume so has to suck up less. Surface area, temperature, are factor that determine how materials diffuse into cells. When they grow volume also grows so diffusion is less effective. 5:2 would have maximum diffusion Bacteria is just one cell they can divide […]

Protein Synthesis Model

Describe the process of translation: initiation, elongation, and termination. Initiation: The ribosome holds the mRNA and reads the start codon, thats when the process first “initiates” Elongation: The ribosome moves along the mRNA, reads each codon and brings the complimentary tRNA. The amino acid chain grows. Termination: The ribosome reads a stop codon, and since there […]

RNA Transcription Model

How is mRNA different than DNA? DNA is made up of deoxyribose sugar while mRNA is made up of ribose sugar. DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base.  DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double-stranded while mRNA is single-stranded. Describe the process of transcription.  Transcription is the process by which […]

DNA and Protein Synthesis-1

Explain the structure of DNA- use the terms nucleotide, anti parallel strands, and complimentary base pairing DNA is made up of molecules called nucleotide. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine, thymine, guanine and cytosine. The order of these bases is […]
