Question

rna• rna differs from dna in three ways:a) rna has a _______________________.b) rna is _____________________.c) rna has _____________________ instead of thymine. (when creating dna,a pairs with t. when creating rna, _____________________.• rna occurs in three forms:a) mrna - _____________________ rna carries the dna \message\ from thenucleus into the cytoplasm on its _____________________.b) trna - _____________________ rna brings _____________________ to the _____________________with its _____________________. trna must recognize both the mrna templatewith the codon and a specific amino acid. trna has a cloverleaf \t\ shape.c) rrna - _____________________ rna is a subunit of the ribosome, the site of proteinsynthesis.step 1. transcription• process in which _____________________ is used as a template to make _____________________.1) rna _____________________ enzyme binds to the _____________________ strand and creates a new_____________________ strand. g=c, t=a, but a pairs with _____________________.2) after a strand of mrna is built, it leaves the nucleus and goes to a_____________________.dna act acg tatmrna _______________________

Explanation:

Step1: Fill RNA-DNA differences

a) single strand
b) ribose (sugar)
c) uracil; A pairs with U

Step2: Fill RNA forms

a) messenger; transfer RNA (tRNA)
b) transfer; amino acids; ribosome; anticodon
c) ribosomal

Step3: Fill transcription basics

DNA; mRNA

Step4: Fill transcription steps

1. polymerase; DNA; RNA; uracil (U)
2. ribosome

Step5: Transcribe DNA to mRNA

For DNA sequence ACT ACG TAT:

• A→U, C→G, T→A
• ACT → UGA; ACG → UGC; TAT → AUA

Answer:

RNA vs DNA Differences

a) single strand
b) ribose (sugar)
c) uracil; A pairs with U

RNA Forms

a) messenger RNA; transfer RNA (tRNA)
b) transfer RNA; amino acids; ribosome; anticodon
c) ribosomal RNA

Transcription

• Process in which DNA is used as a template to make mRNA.

1. RNA polymerase enzyme binds to the DNA strand and creates a new RNA strand. G=C, T=A, but A pairs with uracil (U).
2. After a strand of mRNA is built, it leaves the nucleus and goes to a ribosome.
