Which 2 organelles are most directly involved in transporting materials out of the cell?
The cell structures that are most directly involved in the production and transport of proteins out of the cell are the nucleus and ribosomes. Protein synthesis involves two phases, which are transcription and translation.
What major enzyme is involved in transcription?

What is directly produced by the process of transcription?
RNA Molecules
How many strains of DNA are used for transcription?
During transcription, only one of the two DNA strands is used as a template. This strand, known as the template strand, is read by RNA polymerase to synthesize a complementary RNA molecule. The other strand, called the coding strand, has the same sequence as the RNA (except for the substitution of uracil for thymine) but is not directly involved in the transcription process.
What Transcription factors bind directly to DNA and affect whether and how fast a gene is transcribed?
Transcription factors that bind directly to DNA are classified as either activators or repressors. Activators enhance gene transcription by binding to specific enhancer regions, facilitating the recruitment of RNA polymerase, while repressors inhibit transcription by binding to silencer regions or blocking the assembly of the transcriptional machinery. Examples of key transcription factors include the TATA-binding protein (TBP), which is part of the transcription factor complex that initiates transcription, and various specific transcription factors like NF-kB and MyoD that regulate genes in response to specific signals. Their interactions with promoter and enhancer regions ultimately determine the rate of transcription for target genes.
Is helicase involved in the process of transcription?
No, helicase is not directly involved in the process of transcription. Transcription is the process of making an RNA copy of a gene's DNA sequence, while helicase is primarily involved in unwinding the DNA double helix during processes like DNA replication.
Is tRNA involved in transcription?
tRNA is not directly involved in transcription. tRNA is responsible for transferring amino acids to the ribosome during translation, where it helps in the assembly of the polypeptide chain based on the mRNA sequence. Transcription is the process of synthesizing mRNA from DNA.
Which of these pairs identifies two step directly involved in making a protein?
Transcription and translation are the two steps directly involved in making a protein. Transcription is the process of converting DNA into mRNA, while translation is the process of decoding mRNA to build a protein using amino acids.
Which 2 organelles are most directly involved in transporting materials out of the cell?
The cell structures that are most directly involved in the production and transport of proteins out of the cell are the nucleus and ribosomes. Protein synthesis involves two phases, which are transcription and translation.
The movements indicated by all the arrows are directly involved in?
The movements indicated by all the arrows are directly involved in protein synthesis. This process includes transcription, translation, and post-translational modifications necessary for creating functional proteins within cells.
What two nucleic acids are involved in transcription?
Transcription involves the synthesis of RNA from a DNA template. The two nucleic acids involved are DNA, which serves as the template for RNA synthesis, and RNA, which is the product of transcription.

How is DNA replication affected by a lack of mRNA?
Not at all. mRNA is not involved in DNA replication as it is involved in transcription and translation.
